Human Itch Mite Scabies

human itch mite

What is Scabies

Scabies is an itchy contagious skin disease that affects the skin and is caused by a microscopic itch mite known as the human itch mite Sarcoptes scabiei. The itch mite burrows and lives in the upper layer of the skin of its mammal host and lays its eggs there which results in the infection known as scabies. Animals can get scabies too but the human itch mite is different and can only infect humans or vice versa. This infectious disease occurs all around the world in crowded places.

Scabies Symptoms and Spread

Scabies can spread easily through direct contact with someone who already has the disease. If someone with scabies lives in a house all the family members must be examined for the disease. Since the itch mite is so tiny and very difficult to see it can live on its host’s genital area and thrive in other places where the itch mite lives in the fold of fingers, thighs, knees under bracelets, rings or jewelry, etc. Common symptoms of scabies are:

  • severe itching
  • red itchy patches
  • pimple like scabies rash
  • blisters on the skin

 If left untreated for a long time, scabies can lead to other serious health problems such as chronic kidney disease, septicaemia, and heart disease. Refer to the pictures of scabies body lice bites and infection for better understanding.

How to Prevent Scabies Sarcoptes scabiei

There are many ways to avoid getting scabies. The first and most important way is to keep your skin clean and dry. You should also avoid sharing towels, bedding, clothes, or other personal items with others who may have the infection. If you have been in contact with someone who has scabies, wash your hands thoroughly after you touch them or anything they touched before you touch yourself or anything else.

Healing Scabies How to Treat Scabies

Scabies can be treated with sulfur soap. It is thought to be an old-fashioned remedy for scabies, but it has proven to be effective and inexpensive. Studies have shown that there are minimal side effects, and when used in conjunction with other treatments it does not interfere.

Other means of scabies treatment may vary such as applying creams on your whole body or the use of ivermectin for scabies as per the prescription of your healthcare provider after a brief checkup. Mostly the itch mites die easily and you won’t need to repeat the treatment until the infection returns.

Toxoplasmosis Symptoms and Prevention


What is Toxoplasmosis?

Toxoplasmosis is a parasitic infection caused by a one celled parasite known as Toxoplasma gondii which is found worldwide. This parasite can be transferred to humans via a cat. Toxoplasma gondii, the parasite that causes toxoplasmosis, is transmitted by contact with cat feces and infected raw meat. The most common way people get infected is by eating raw or undercooked meat containing the parasite. More than one third of Americans have been exposed to toxoplasmosis

Human Infection and Symptoms of Toxoplasmosis

Humans can become infected in the following ways: Accidental ingestion of oocysts after cleaning the litter box, if Toxoplasma is present in the cat’s faeces. Accidental ingestion of oocysts after touching or ingesting objects that have come into contact with cat feces containing Toxoplasma gondii.

The most common symptoms of the infection are almost identical to flu such as:

  • Body pain
  • Tiredness or Fatigue
  • Swollen lymph nodes
  • Headache
  • Body Temperature (Fever)

If left untreated, this illness can cause loss of vision. However, when the immune system is weakened, toxoplasmosis can lead to seizures, complicated life-threatening illness, or serious brain infections. Untreated encephalitis caused by toxoplasmosis can be fatal in AIDS patients.

Tips on How to Prevent the Infection

It can be transmitted to humans when they come in contact with the feces of infected cats.

So the best way to prevent the sickness is to avoid contact with cat feces and wash hands thoroughly after gardening or any other outdoor activity that might bring you in contact with soil or sand where a cat may have defecated.


Once the diagnosis of toxoplasmosis is confirmed, you can discuss with your doctor whether you need treatment. In otherwise healthy people who are not pregnant, no treatment is usually required. If symptoms develop, they usually disappear within weeks to months.

What is Tularemia Rabbit Fever

A rabbit fever also known as tularemia, rabbit fever is a bacterial infection that is most often transmitted to humans through the bite of an infected animal, most commonly a rabbit or deer fly. This infection can also be contracted by inhaling bacteria-laden dust from infected animal carcasses or through contact with contaminated soil or water.

What is Tularemia

Symptoms of Rabbit Fever

Rabbit fever symptoms can range from mild to life-threatening and include fever, chills, headaches, muscle aches, joint pain, diarrhea, poor appetite, vomiting poor appetite, and vomiting if the bacteria enter the bloodstream. If you think you may have been exposed to the bacteria that causes tularemia, see your healthcare provider immediately or go to the emergency room.

Rabbit Fever Treatment

There is no specific vaccine available, but it is possible to prevent the virus from spreading by thoroughly cleaning any surface that may have come into contact with a rabbit, and by avoiding contact with wild rabbits. While there is no cure for rabbit fever, most people recover without any permanent damage.  If you think that you have the virus, see a doctor.

Tularemia is a serious disease and if left untreated can be fatal. Early diagnosis and treatment are critical. If you think you may have been exposed to the bacteria that causes tularemia, see your healthcare provider immediately or go to the emergency room.

Rabbit Fever Sources

Rabbits are the main source of tularemia in the United States, but the disease can be transmitted by many different animals, including deer, rodents, and birds. In most cases, tularemia is not passed from person to person. The incubation period for tularemia is usually three to five days but can range from one to 14 days. Symptoms of tularemia can include fever, chills, headaches, muscle aches, joint pain, diarrhea, poor appetite, and vomiting.

Pubic Lice | Phthirus Pubis Infestation

Pubic lice (Pediculosis pubis), also known as crabs, are small, parasitic insects that feed on the blood of human beings. They are most commonly found on the pubic area, but can also be found on the arms and legs. Pubic lice are easily identified by their small size and the fact that they have two pairs of legs. They can also be distinguished from genital crabs by the lack of a penis.

pubic lice

Pubic lice can be found on both men and women, but are more common on men due to their close physical proximity to the groin area. They are small, brown or gray parasites that live on the skin, and can cause discomfort and itching. Although pubic lice are not known to cause any serious diseases, they can spread skin diseases such as scabies.  pubic lice are common in schools and homeless shelters, where they can spread infections more easily.

Pubic Louse Life Cycle

The public lice lifecycle is outlined below:      

 1) Infection: Lice are transferred from person-to-person through close contact, such as sharing clothes, combs, or brushes.  

2) Development: Lice hatch from eggs and begin to feed. 

3) Reproduction: Lice lay eggs and the cycle continues.

Adult lice live about two to four weeks and nymphs about one to two weeks.  They are active during the daytime and feed on the blood of their host. Pubic lice can spend anywhere from two to twelve weeks crawling on the human body. During this time, they can lay up to 2,500 eggs.

These tiny, blood-sucking insects can cause serious problems if they’re not treated.

Symptoms of Crab Lice Infestation

Symptoms of Crab Lice Infestation Include:  

1) Intense itching in the genital area. 

 2) Tiny eggs (nits) attached to the base of hair shafts. 

 3) Visible lice crawling on the skin. 

 4) Irritated, red skin.

crab lice

Some other symptoms of pubic lice include itching and the presence of lice or their eggs in the pubic hair. The itching is caused by an allergic reaction to the louse’s saliva.  If you have pubic lice, you may also have them in other areas of your body that are covered with hair, such as your eyebrows, eyelashes, armpits, beard, mustache, chest, and back.

Can you see crabs STD? If you look closely, you might but some people might need a magnifying tool in order to see the crabs.

Crabs STD Treatment

There are many ways to get rid of pubic lice. Some people prefer to use over-the-counter medications. Others prefer to use home remedies. Some people use both.

Once you’ve determined you have pubic lice, you need to get rid of them. You can treat pubic lice at home or go to a doctor. If you’re pregnant or have a weakened immune system, talk to your doctor first before using any treatments. The most common treatments are over-the-counter lotions or shampoos.

Crabs can be treated with a pesticide or a larvicide. The pesticide is more effective but is also more toxic. The larvicide is less toxic but less effective. Both types of treatment should be repeated every three weeks for at least six months, depending on the severity of the infestation.

The most important part of treating crabs is to remember that they live in the cracks and crevices of the body, so any treatment should be directed to those areas. The easiest way to treat crabs is to use a medicated cream or lotion that is available without a prescription. The cream or lotion is applied to the pubic hair and skin around the groin area. It is important to apply the cream or lotion to all of the cracks and crevices in the skin, not just to the pubic hair.

In order to get rid of crab lice, you must treat the infestation with an effective pesticide.

Ways to Prevent Pubic Lice

Preventing pubic lice is important. There are a few things that can be done to help avoid them. First, keep your hair clean. Second, avoid sharing clothes and bedding. One of the most effective ways to prevent them is to use a good personal hygiene routine.

Don’t Let The Liver Fluke Kill You

Mystery parasitic worms that hide in your gut meet your newest friends, the liver fluke (Dicrocoelium dendriticum).

liver flukes

What is a Liver Fluke

Liver flukes are a type of parasite that resides in the human liver. Liver flukes are also known as fascioliasis or fasciolosis. The two most common species are called Fasciola hepatica and Fasciola gigantica. These parasites feed on the bile ducts of their host’s liver, causing inflammation and scarring to it. If left untreated, this can lead to cirrhosis or cancer in the liver.

It is a worm that has an elongated body and it has two suckers at its anterior end. It also has a crescent-shaped mouth at the posterior end of its body. The human liver fluke is found around the world and it can infect any species of mammal, but humans are usually infected by eating undercooked fish.

The adult worm resides in the bile ducts of the liver and it can grow to about 2 inches long. The eggs that are released from this parasite are passed out in feces or urine and then they are consumed by other animals or humans, who become infected when they eat raw or undercooked fish containing these eggs.

They are also present in cattle and other mammals. Liver flukes have a life cycle that consists of three different stages: eggs, miracidia, and the adult form.

They have a complicated life cycle with at least three different hosts. There is a definitive host which is usually an animal such as cattle, sheep, or deer and there’s an intermediate host which is usually a snail or fish. The final host is the human body where the eggs hatch and grow into adults in the liver.

Liver flukes are mostly transmitted through fecal contamination. This can happen when people come into contact with water or food that has been contaminated with feces from an infected person or animal.

Liver fluke symptoms

Liver fluke symptoms include abdominal pain, diarrhea, weight loss, fever, nausea, vomiting, and jaundice. Common symptoms are stomach pain and diarrhea.

liver fluke life cycle

Liver flukes in stool

The eggs of these parasites can be found in stool samples of infected people. The eggs will pass through the intestines and end up in the stool sample. They need to be identified under a microscope by a trained professional to diagnose them correctly.

Treating liver flukes

It’s a difficult process, but it can be achieved. The best way to treat them is to use the following:

– Anthelminthics (praziquantel, niclosamide)

– Mebendazole

– Pyrantel pamoate

– Albendazole

– Ivermectin

– Levamisole

Never taking any medication without consulting your healthcare provider

Mind Control Fungus | Zombie Fungus

Have you ever heard of a disease that can turn you into a zombie? Well! you are about to now! Let’s talk about a fungus which has mastered the art of mind control. Zombie fungus also known as the MIND CONTROL FUNGUS.

mind control fungus

The fungus ophiocordyceps unilateralis is found in the tropical forests, ophiocordyceps unilateralis fungus is a zombie bug fungus and related species can infect more than 400 types of insects mostly caterpillar ants therefore it’s also referred as zombie ant fungus.

Mind Controlling Fungus Infection

Ants infected with fungus (ophiocordyceps unilateralis) is doomed and will slowly die as it’s a fungus that takes over ant’s body and mind, the parasitic fungus will eat its host from the inside consuming its body fluids and controlling its mind hence it’s called the mind control fungus. Once the fungus is done feeding on the ant’s nutrients it will force its host to act abnormal and make it leave its nest and head to a close by stem of a plant the infected will also develop atrophy in the parasitic fungus ant’s / host insect and will stop the insect to reach a height of 25 cm as it’s the perfect humid environment foe the fungus to grow until its ready to burst out of its hosts body.

mind controlling fungus
Read Eye Worm in Human

The cordyceps mind controlling fungus ants will grab the stem/leaf tightly locking its jaw (death grip) and will eventually die there. Then the pathogenic fungus will burst out of zombie ants head and spread spores below causing more infections to occur as other ants will be walking over the spores.

Ophiocordyceps unilateralis in humans is not possible as it can’t infect humans! yes you’ve heard that right ophiocordyceps unilateralis in humans is NOT POSSIBLE! Happy now? gladly we humans are safe from this horrendous fungus and zombie fungus humans is not going to happen hence there won’t be any zombie apocalypse in the near future due to this the fungus any time soon.

Wolbachia Bacterial Parasite | The Sex Changer

Wolbachia Bacterial Parasite

Wolbachia Bacterial Parasite

What is the wolbachia bacteria? Wolbachia bacterial parasite is an intracellular bacteria, mainly affecting species of arthropods, some nematodes and a significant number of insects. Wolbachia bacterial parasite may be a highly common microbial parasite as well as being most commonly known reproductive parasite.

Complex Relationship with the Host

Being a parasite the relationship with the host is often complicated or complex. There are some mentioned cases where the relationship has a symbiotic pattern along with being parasitic. As there are some species of the hosts of the wolbachia bacterial parasite that without the presence of the colony of the parasite may not be able to even survive let alone multiply.

Organs Affected by Wolbachia

A number of different organs are affected by the bacteria known as what is wolbachia bacteria. Although the main organs that are infected with this bacteria are the reproductive organs for example the ovaries and the testes of the hosts. The females of the infected hosts can transfer the infection to their progeny. As with any species of organism, the wolbachia bacterial parasite maximizes its spread by changing the capabilities of reproduction in their hosts.

What is a Babesosis / Babesia Infection

The Mosquito Connection

There are some species of mosquitoes that spread different viruses like chikungunya, Zika and dengue. These include the Aedes species of the mosquitoes, which are quite common especially in the United States. This wolbachia bacterial parasite is not found naturally in this mosquito. These are introduced by scientists into the mosquito eggs, and these become wolbachia mosquito. Now when these male wolbachia mosquitoes mate with wild female mosquitoes (without Wolbachia) their eggs do not hatch.

Wolbachia Treatment

The so called wolbachia treatment is that these male wolbachia mosquitoes when released in the area prevent the population from spreading which is attributed to the non-hatching of the eggs when wild female (without wolbachia bacterial parasite) breed with the wolbachia male. Hence the prevalence of the diseases spread through these mosquitoes species is reduced.

Production of Wolbachia Mosquito

The production of the wolbachia species of the mosquito is through the introduction of the wolbachia bacterial parasite into the eggs of the aegypti mosquitoes. The new mosquitoes that are now bred in these eggs will have wolbachia bacterial parasite.

These parasites affect the reproductive pattern and only males of this breed is released after the sorting of the genders. Although females are used for breeding purposes in the laboratory. This is how these are mass produced after the wolbachia treatment. This is called the metodo wolbachia or wolbachia method.

Cytoplasmic Incompatibility

Cytoplasmic incompatibility is the reason why these eggs do not become viable. Cytomplasmic incompatibility is the name given to the phenomenon where the male sperm cells and the female egg cells are not compatible enough to form viability of egg cells.  This happens in a wide range of insects which are infected by this type of wolbachia bacterial parasite.

Horsehair Worm Nematomorpha in Human Diagnosis

Since affect does not pass from the male to the next generation due to the cytoplasmic incompatibility, so the females are kept for the horizontal transmission of the parasite to the next generation. And since the wolbachia mosquito has the parasite transferred maternally, the host and parasite relationship becomes quite intimate. Although it does not affect the health of the host significantly, the overall impact is only on the reproductive organs.

World Mosquito Program Wolbachia

The World Mosquito Program wolbachia is a program that aims to prevent the illnesses like yellow fever, chikugunya, Zika and dengue. Through the World Mosquito Program wolbachia the transmission is prevented of such mosquito borne diseases. This has been proven and monitoring shows that where the wolbachia mosquito population at a higher level and it appears to be self-sustaining. The viral transmission reduces significantly.

The first batch of the wolbachia mosquito was released in 2011 and since then different studies are showing that risk of transmission of different viruses can be greatly decreased by the use of the wolbachia mosquito. Other than that there are different trials conducted at multiple locations that acknowledge that the World Mosquito Program Wolbachia is not only effective but also safe as well, that prevents the disease spread in cities and entire regions. And they claim that the metodo wolbachia or the wolbachia method is a safe and effective way to reduce the burden of the mosquito borne diseases in the population.

Around the World

The project is active around the world in more than 10 countries and their wolbachia mosquito (the wolbachia carrying mosquitoes) had reached around 6 million people and this is the number reported by December 2020. The program is running through regional hubs and currently has 02 (two) hubs, one in Australia and the other in Vietnam. In Melbourne and Ho Chi Minh City respectively.  They have not stopped there, they are looking to establish another center or hub in the Americas probably in Panama. The global operations are carried out through the regional centers or hubs which then implement the core operations locally.

Heartworms Infection and Prevention

And this all started from the discovery of bacterium wolbachia in 1924, when researchers discovered this bacterium. And this is where the journey of the world mosquito program wolbachia actually started.

 In the US (United States)

Not only the world mosquito program wolbachia, but in 2017, even an affliated company to google came forward with their plan for a 20 million wolbachia mosquito release. This release was to occur in California as they tried to combact and decrease the disease burden of the Zika virus in the region.

Also in 2017 a company was registered known as the mosquito mate; which was registered with the EPA (US Environment Protection Agency). The aim was to release the Wolbachia mosquitoes in around 20 US States as well as the District of Columbia.

Other than the US, the Agency for the Environment of Singapore has also teamed with the Google affiliate. This would be a research into the development and later on deployment of a more efficient and a more advanced way to release the wolbachia mosquitoes. They also plan to study and suppress the Aegypti Mosquito population in the urban areas so as to fight dengue.

Guinea worm disease eradication | Dracunculus

Guinea worm disease eradication

Guinea worm disease eradication is an important issue for most of the tropical African and Asian regions even in the tropical South America and West Indies, as this is where Dragon worm is found. Due to the parasite’s invasion of a variety of mammals it is important for the people to be worried about the guinea worm disease eradication. There are many different forms of worm sicknesses or worm disease, and dracunculiasis guinea worm disease is one of them.

Belonging to the phylum Nematoda; dracunculus parasite (Dracunculus Medinensis) also known as the Dragon Worm is a parasite that affects humans and mammals as well. The disease caused by the dracunculus parasite is called dracunculiasis guinea worm disease or dracunculiasis simply.

Dracunculus Parasite

Also called the guinea disease, the dragon worm is a roundworm, and it penetrates the gut and travel to the connective tissue. The guinea worm larvae or the new guinea worm larvae as they are known have a four stage development cycle and this is all before the formation of adult dracunculus worm. The dracunculus worm can grow to a length of 80cm, and are among the largest nematodes known species.

These new guinea worm have a dual host cycle, which involves an intermediate host. These hosts are  where the infective guinea worm larvae develop. Then these vertebrates or aquatic crustaceans are ingested by the definitive host (humans or mammals) through drinking unfiltered water, containing these copepods.

Guinea worm larvae

The guinea worm larvae do not come from eggs but the dragon worm female give birth to live larvae. This is the reason that guinea disease causing dracunculus parasite is called ovoviviparous, as it does not lay eggs.

In humans, the guinea worm infestation cause blisters with are painful. Guinea worm larvae are released through these blisters. It may come as a surprise to you, but this guinea disease is quite well known. The staff with serpent logo that has been adopted as the official symbol of medicine reflects the same dracunculus worm along with a stick winding it, this depicts the traditional removal techniques at the time.

Historical instances

Guinea worm infestation in humans also have a history of being recorded earlier in history books. Described to the likes of little snakes by scholars both Roman and Greek, they even have been described as fiery serpents in some texts.


Guinea worm disease or Guinea disease occur in desert and the semi – desert areas of the Middle-East, India, Brazil and the sub – Sahara of the Africa. But mainly in areas which are not urban i.e. rural areas. In these areas, due to the scarcity of water resources the water that is available is from ponds of the rainy seasons or from wells drawn from the soil. Due to World Health Organization’s preventive campaigns the estimated prevalence of guinea worm disease has been markedly reduced.

Affected Species

This worm disease (Guinea disease) has been reported occasionally in mammals like horses, dogs, cattle and cats. Even species of crocodiles, some water birds, turtles and snakes have also been described as affected by this worm sickness. Other species of this disease have also been known to affect raccoons, carnivores, possums or muskrats in the Americas as well.

The Tongue-eating parasite | Cymothoa Exigua

Site of Infestation

The larvae that are ingested arrive at the connective tissue by penetrating the gut. They migrate to the inguinal and/ or axillary regions after invading the subcutaneous connective tissues. The female dracunculus parasite then migrate to the locations in the peripheral subsurface from the deep connective tissues. Especially in the legs or arms (extremities), this does not mean that they cannot occur anywhere else, but the extremities are the places where they occur most commonly.

Signs and Symptoms

Until the mature female dragon worms travel to the skin and form a papule or a blister, these usually are symptomless or asymptomatic, even though they can grow to very large sizes. When traveling these may produce some localized swelling, or some allergic reactions like diarrhea, dizziness, nausea and rashes. There are generally two types of infectious lesions; one that occur subcutaneously or some that are around dead worms (deep abscesses) this involves many inflammatory cells that become blister after calcification (papules), this is how they directly release larvae, as there are no eggs. Sometimes these skin lesions may also involve redness, intense pain (burning sensation) as well as ulceration.

Eye Worm in Human | Loa Loa Filariasis

Guinea Worm Removal

The guinea worm removal is a process where cool water immersion is used to relieve the symptoms of this worm sickness. Due to the hypersensitivity reaction, which is induced from the larval deposition in the tissues, blisters are formed. These blister then burst and parts of the adult worms emerge out, this is the way these tissue dwelling parasites get expelled from the host. In some cases of uncomplicated infections the lesion only lasts until the worm is completely removed from the body.

Secondary infection

But some cases do get involved with secondary infection, which is usually bacterial. These secondary infections cause a number of different sequelae of events which may make this infection and guinea worm disease treatment complicated. These may involve fibrous ankylosis, different disseminated infections, chronic ulceration and contractures of tendons.


There are some very old and traditional methods of guinea worm removal. This involves the slow winding of the dragon worm on a stick several centimeters a day for some weeks. It is important to avoid force as excess of force might break the worm and complicate the infections and guinea disease.

There is a surgical procedure involving the removal of the dracunculus worm when present in the superficial sites of the body. If the involvement of deeper tissues and fascia is present, surgical treatment may be difficult to perform. Guinea worm disease treatment through some anthelminthics have not been proven efficacious, but some molecules like mebendazole, albendazole or even metronidazole have shown some encouragement, and plays and important role in Guinea worm disease eradication process.

Please consult your treating physician before taking any medication.


There are some preventive measures that can break the transmission cycle, like the elimination of copepod by reduction of the contamination. Educating the public through different programs, and purification of water by boiling or filteration. Even the treatment of local water supplies can reduce the prevalence dramatically.

Eye Worm in Human | Loa Loa Filariasis

eye worm

A parasitic eye worm, also known as African eye worm, is known as Loa loa. The infection is called loa loa filariasis. This eye worm parasite is transferred to humans by the bite of deerflies or mango flies, of the genus Chrysops. These flies get infected by biting and sucking the blood of an infected person first. These are most commonly found in the rain forests of Central and West Africa. People traveling from these areas, when bitten with these flies are usually affected. This is a relatively very rare disease. But before we get on the description of the Eye worm or Eye Parasite let’s first look at what are parasites?


Parasites are organism that derives food and nutrition and also lives on the host and thus depends completely on the host. At the expense of the host the parasite derives nutrition and actually survives on the host’s food and shelter. The parasite effectively deprives the host of the nutrition that it needs.

These parasites typically live in or on the bodies of the host organism. Some parasites are also harmful, since they can cause infections. If they are inside the body, such organisms then reach their destination organ, eyes are just such organs i.e. Eye parasites. There can be different types of parasites; Protozoa, helminthes or Ectoparasites.

Symptoms of Eye Parasites

General symptoms of eye parasites are not always very apparent. And they may also be difficult to understand and recognize. These may include inflammation of the eyes, or redness, blurry vision, sensitivity to light, excessive tear production, pain in the eyes, crusting eyelids, retinal scarring, and also blindness or loss of vision

The signs and symptoms of eye parasites are not very apparent in most people, and usually do not even present themselves for days or even months after inoculation. Although with loiasis or African eye worm infection, the most commonly presented are swellings which are non-painful, these may be accompanied with itchiness, around the swelling. These are not persistent, but usually transient meaning that these swellings come and go. The Loa Loa filariasis symptoms may be swellings, itchiness and irritation.

There may be worm in eye symptoms; that is development of an eye worm crawling inside the surface of the eye. There may also be other symptoms like worm crawling under the skin, or swelling in and around the joints, or itching in different parts of the body. These symptoms may present along with high levels of eosinophils in the blood, which can be seen in blood reports. There are different eye parasites in humans, some of which are given below:

Eye Parasites in Humans

Other than loa loa filariasis there are other organisms that can be eye parasites in humans. Acanthamoeba may be such an organism. This organism can effect vision and can be dangerous. Transmission usually is through direct contact in the marine and fresh water environments in which it is present. Another Eye parasite may be toxoplasmosis, present in mostly animal waste especially among pets for example cats. Its transmission is through ingestion, although a thing of concern is that the parasite can be passed in pregnancy from mother to the fetus. As is typical of eye parasites normally do not present with signs or symptoms. Immuno- compromised individuals especially children develop eye worm infections. But if left untreated, they can cause severe scarring or even vision loss.


Seeing worms in eyes would be a terrifying experience, but that’s what happens with Loiasis. This is caused by a helminth parasite, as discussed before mostly found in Africa. T Endemic to the West and Central Africa Loiasis infection is from the filarial nematode called Loa loa. The infection is acquired from the infected fly bite, this parasite is then transferred to the body where it develops and then migrates to different areas and tissues. The produced larvae are called microfilariae. Not only the adult worm, but the larvae as well can cause issues in the eye or vision for example impaired movement of the eyes, sensitivity to the light, vision problems and eye pain.


Another eye parasite or human eye worm can be Gnathostomiasis, this particular helminth or human eye worm is found mostly some parts of South America or Central America, and Africa, Southeast Asia, Japan and Thailand. The transmission of infection of this eye infesting worm is through the mouth that is by ingesting uncooked food or raw food like fish or meat. The eye infesting worm or eye parasite then goes to different parts of your body, eyes included from the gastrointestinal tract. This parasite in eye symptoms can affect the eyes vision partially or even in some cases fully.

River blindness (onchocerciasis)

Onchocerciasis is also an eye worm which is a helminth. These parasites are found in the South and Central Americas, the Middle East and some parts of Africa. This is often also known as river blindness. The larvae enter the body through the bite of a blackfly which is already infected or exposed to the parasite. This eye parasite will burrow into the skin and then develop to adults, where they will reproduce so that they can enter into different organs and tissues. If they reach the eyes, the parasite in eye symptoms maybe that it may cause blindness.

Treating Eye Infections

As is the case with any disease the treatment depends upon the type of infection. Or in this case upon the type of parasite, whether eye parasite removal may be necessary or some eye drops to kill parasites would be a better approach. Although different types of medications including topical and oral are available depending again upon the type of infection and parasite. Diethylcarbamazine, ivermectin, or pyrimethamine usually the medicines used for such eye parasites. While some eye worms can be treated through such medicines. But in some extreme cases eye parasite removal may be the recommended approach. Such is the treatment of eye parasites including loa loa filariasis, river blindness,and or gnathostomiasis.

Worst Parasites in Humans

worst parasites in humans

Let talk about some worst parasites in humans? Parasites are organisms that are the ultimate opportunists. They survive on the nutrition of the host, and they do not contribute anything to it. In humans, they live off the food and nutrition of the human feeds on and they thrive on it. Worst parasites in the world are those parasites can’t even survive without a host, rather a human host. Meaning if the host for some reason dies; the parasite will also die, since they will not be able to derive nutrition anymore from the host, so eventually it will die.

There are many parasites that can be considered worst parasites in the world or worst human parasites, let’s see if the following list can be considered the same


tick parasite

Ticks are the one of the most well- known external worst parasites for humans. Since they live outside the body that is on the surface of the body and do not enter the body; they are known as ‘ectoparasite’. The problem with the tick is the bite of the tick, through which a number of harmful diseases can be caused, e.g. rickettsia and Lyme disease.

Although the tick bites can be considered harmless, they can cause trouble if they transmit some sort of infection. Mostly they won’t even be noticeable, if no symptoms are visible. But there is almost always a chance of some sort of allergic reactions to occur. Some people might be allergic to the ticks’ bite, which may become quite dangerous for the human host. In some instances they can also become deadly if not treated immediately. Can ticks qualify for being the worst parasites in humans, you decide.


Plasmodium parasite

There are a lot of people who contract malaria the world over, millions of cases every year. However the world over everyone believes mistakenly that malaria is an infection caused by a bacteria or a virus. Although caused by a single celled organism; plasmodium, this is not a bacteria or a virus. Plasmodium is a protozoa species which is also a parasite. It is transferred to humans through an infected mosquitoes bite. Plasmodium may not appear to be worst parasites but the harm generated from the disease that they cause can certainly be considered to be one of the worst. The disease malaria although treatable is not preventable from vaccination, but you can take measures to prevent it through various means like spraying, using mosquito repellants, nettings etc.
