- Filariasis (or philariasis) is a parasitic disease caused by an infection with roundworms of the Filarioidea type.These are spread by blood-feeding black flies and mosquitoes. This disease belongs to the group of diseases called helminthiasis.Eight known filarial nematodes use humans as their definitive hosts. Lymphatic filariasis is caused by the worms Wuchereria bancrofti, Brugia malayi, and Brugia timori. 2  These worms occupy the lymphatic system, including the lymph nodes; in chronic cases, these worms lead to the disease elephantiasis.

Frequently Asked Questions (FAQs) Lymphatic filariasis is a parasitic disease caused by microscopic, thread-like worms. The adult worms only live in the human lymph system. The lymph system maintains the body's fluid balance and fights infections.eople get lymphatic filariasis from the bite of an infected mosquito. The microscopic worms pass from the mosquito through the skin, and travel to the lymph vessels. In the lymph vessels they grow into adults. An adult worm lives for about 5–7 years.

Wuchereria bancrofti Wuchereria bancrofti is distributed throughout the tropical regions of Asia, Africa, China, the Pacific and isolated locations in the Americas. Current estimates (WHO, 1994) suggest that 100 million people are infected with lymphatic filariae of all types, and most of these cases are bancroftian filariasis.

- Lymphatic filariasis is caused primarily by adult worms (filariae) that live in the lymphatic vessels. The female worms release microfilariae that circulate in the peripheral blood and are ingested by mosquitoes; thus, infected mosquitoes transmit the infection from person to person.

Other areas commonly affected include the external genitals. Elephantiasis is caused by obstruction of the lymphatic system, which results in the accumulation of a fluid called lymph in the affected areas.

Mydriasis Mydriasis (/mɪˈdraɪ.əsɪs/) is the dilation of the pupil, usually having a non-physiological cause,[1] or sometimes a physiological pupillary response.[2] Non-physiological causes of mydriasis include disease, trauma, or the use of drugs.

- Elephantiasis refers to a parasitic infection that causes extreme swelling in the arms and legs. The disease is caused by the filarial worm, which is transmitted form human to human via the female mosquito when it takes a blood meal. The parasite grows into an adult worm that lives in the lymphatic system of humans.

elephantiasis There are a few different causes of elephantiasis, but the agents responsible for most of the elephantiasis in the world are filarial worms: white, slender round worms found in most tropical and subtropical places. They are transmitted by particular kinds (species) of mosquitoes, that is, bloodsucking insects.

Elephantiasis Photo by: Henrik Larsson. Elephantiasis (el-e-fan-TY-a-sis) is the result of a tropical worm infection called filariasis (fil-a-RY-a-sis). When infected mosquitoes transmit the parasitic worm Wuchereria bancrofti to people, the worm blocks the lymphatic system.The blockage causes swelling in the legs or other parts of the body, making these body parts appear large and puffy, or elephant-like.Elephantiasis is not elephant man disease, which is an inherited condition with completely different causes and symptoms.he blockage causes swelling in the legs or other parts of the body, making these body parts appear large and puffy, or elephant-like.

Mydriasis Mydriasis. Mydriasis /mɨˈdraɪ.əsɪs/ is the dilation of the pupil, usually defined as when having a non-physiological cause, but sometimes defined as potentially being a physiological pupillary response. Non-physiological causes of mydriasis include disease, trauma, or the use of drugs. Normally, as part of the pupillary light reflex, the pupil dilates in the dark and constricts in the light to respectively improve vividity at night and to protect the retina from sunlight damage during the day.

Practice Essentials In lymphatic filariasis, repeated episodes of inflammation and lymphedema lead to lymphatic damage, chronic swelling, and elephantiasis of the legs (see the image below), arms, scrotum, vulva, and breasts. Filariasis.

- Summary. Myiasis is a parasitic infestation of the skin that is caused by maggots, which are the developing larvae of the flies. Myiasis is mainly an infection of animals. But it may also affect humans, particularly those who live in rural, tropical and sub-tropical areas.yiasis is caused by the maggots of the flies. It is usually a condition of animals but occasionally humans may also get infected. There are numerous flies whose maggots can cause Myiasis.

Loa loa filariasis Loa loa filariasis. [edit on Wikidata] Loa loa filariasis is a skin and eye disease caused by the nematode worm Loa loa. Humans contract this disease through the bite of a deer fly or mango fly (Chrysops spp), the vectors for Loa loa. The adult Loa loa filarial worm migrates throughout the subcutaneous tissues of humans, occasionally crossing into subconjunctival tissues of the eye where it can be easily observed. Loa loa does not normally affect one's vision but can be painful when moving about the eyeball or across the bridge of the nose.

There are 3 known species of the filarial nematode that can cause lymphatic filariasis: Wuchereria bancrofti, Brugia malayi and Brugia timori.

elephantiasis True elephantiasis is the result of a parasitic infection caused by three specific kinds of round worms. The long, threadlike worms block the body's lymphatic system—a network of channels, lymph nodes, and organs that helps maintain proper fluid levels in the body by draining lymph from tissues into the bloodstream.lephantiasis. 1. a chronic filarial disease, usually seen in the tropics, due to infection with Brugia malayi or Wuchereria bancrofti, marked by inflammation and obstruction of the lymphatics and hypertrophy of the skin and subcutaneous tissues, chiefly affecting the legs and external genitals.

Elephantiasis (Elephantitis) Disease, Types, Pictures, Treatment What is elephantiasis? Elephantiasis is a condition where the skin thickens and hardens after excessive swelling associated with lymph accumulation (lymphedema). It is most marked in the lower limbs but also commonly affects the scrotum in males, and may also affect the breasts and arms.

- Treatment of chronic filariasis does not change the prognosis, as irreversible fibrosis usually destroys lymphatic tissue. However, asymptomatic patients, hoping to diminish progression of the disease, still typically undergo treatment, although the benefit of this is unclear.

Frequently Asked Questions (FAQs) Men can develop hydrocele or swelling of the scrotum due to infection with one of the parasites that causes LF, specifically W. bancrofti. Filarial infection can also cause tropical pulmonary eosinophilia syndrome. This syndrome is typically found in infected persons in Asia.he disease spreads from person to person by mosquito bites. When a mosquito bites a person who has lymphatic filariasis, microscopic worms circulating in the person's blood enter and infect the mosquito.
