Elephantiasis is caused by a couple of different things such as the bite of a mosquito, or that of a biting fly infected either of which is infected with a worm parasite what this worm parasite does is it works its way into the body and causes a blockage that interrupts the regular lymphatic system flow. Lymphatic filariasis, also known as elephantiasis, is a human disease caused by parasitic worms known as filarial worms   most cases of the disease have no symptoms  some people, however, develop a syndrome called elephantiasis , which is marked by severe swelling in the arms, legs, breasts , or genitals. The mature worm is mostly located in the lymphatic system and may cause impairment of lymph nodes, which lead to the blocking of lymph flow throughout the body lymph flow is essential for the host immunity, so impairment in the flow causes chronic lymphedeme mostly in the lower part of the body. Video explaining the parasitic life cycle of lymphatic filariasis in humans. These worms lodge in the lymphatic system, the network of nodes and vessels that maintain the delicate fluid balance between the tissues and blood and are an essential component for the body’s immune defense system.
Lymphatic filariasis, considered globally as a neglected tropical disease (ntd), is a parasitic disease caused by microscopic, thread-like wormsthe adult worms only live in the human lymph system the lymph system maintains the body’s fluid balance and fights infections. The term lymphedema, which is synonymous with lymphatic edema, means a swelling of some part of the body due to a fault in the local lymphatic system (kinmonth 1982) chronic lymphedema–elephantiasis is one of the most common chronic manifestation of lymphatic filariasis. The adults of the lymphatic filariae inhabit lymph vessels, where blockage and host reaction can result in lymphatic inflammation and dysfunction, and eventually in lymphedema and fibrosis repeated, prolonged infection with these worms can lead to elephantiasis, a buildup of excess tissue in the affected area. Worm larvae deposited by the bite of an infected mosquito enter the body and migrate to the lymphatic system, where they mature into adult worms the thread-like parasitic worms can live and.
In mammals filarial worms cause a group of infectious disorder including heartworm , elephantiasis , and river blindness these disorder are known collectively as filariasis. Home » parasitic diseases » elephantiasis: definition, causes, process of regenerating, symptoms, and prevention elephantiasis: definition, causes, process of regenerating, symptoms, and prevention it is a common disease in africa it is a significant disease that shows how much damage can be caused by mosquito or worms. Elephantiasis is caused by 3 different types of parasitic worms, including wuchereria bancrofti, brugia malayi, and brugia timori this is also known as lymphatic filariasis non-filarial elephantiasis is caused by repeated contact with volcanic ash in the area. Elephantiasis, is a parasitic infection due to filaria worms--a type of nematodemosquitoes are the vector that carries the parasite they must bite a person and inject the worm and bacteria in the worm which causes an immune response in the host it is a tropical disease.
Lymphatic filariasis is a complex interaction between several factors the worm, symbiotic wolbachia bacteria within the worm, the host’s immune response and any number of other opportunistic infections that arise to take advantage of the impaired immune defenses of an obstructed lymphatic system as the parasites accumulate in lymph.

Lymphatic filariasis page 1 akre m adja,sina helbig, alia tayea, neil arya • adult worms reside in the lymphatic system of the human host • mature infective larvae then migrate to the mouthparts of the mosquito from where they enter. These larvae are transported to the lymphatic system, where they mature into reproductive adult worms and reside for a number of years female worms generate microfilariae, which eventually are ingested by mosquitoes and become the highly infective filariform worms.
Worm larvae that make their way into lymph vessels can mature into adult worms male worms are long and slender, about 4 to 5 cm long, and 01 mm in diameter female worms are much larger, 6 to 10 cm long, and about three times wider than the males. The larvae enter the skin via the wound made by the mosquito, migrate through the tissues and into the peripheral lymphatic system the worms typically mature in the larger lymph vessels, usually in the lower limbs and the genital region. Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease infection occurs when filarial parasites are transmitted to humans through mosquitoes infection is usually acquired in childhood causing hidden damage to the lymphatic system the painful and profoundly. After about a year, the larvae moult through two more stages, mature into the adult worms the disease is spread from person to person by mosquito bites when mosquito bites a person who has lymphatic filariasis, microscopic worms circulating in the person's blood enter and infect the mosquito.
Finally, the worm larvae migrate to the lymphatics via the bloodstream and mature in the lymph system risk factors elephantiasis can affect anyone who is exposed to the parasites that cause the. 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. Lymphatic filariasis, commonly known as elephantiasis, is a painful and profoundly disfiguring diseasewhile the infection is usually acquired in childhood, its visible manifestations occur later in life, causing temporary or permanent disability. Elephantiasis (facts and history) overview elephantiasis is a common term for either lymphatic filariasis or podoconiosis these are two different diseases but they both cause enlargement of lower extremities that would appear like an elephant’s limb and thus accountable for the term.
These worms affect the lymphatic system especially the lymph nodes chronic cases of lymphatic filariasis lead to the disease elephantiasis subcutaneous filariasis: it is caused by the loa loa worm which burrows themselves in the subcutaneous fat layer right under the skin. The slide toward elephantiasis begins when the lymph vessels become enlarged and blocked as a result of the presence of adult worms lymph accumulates in the tissues instead of flowing through the vessels back to the bloodstream, and permanent swelling occurs with thickening and folding of the skin. Elephantiasis, also known as lymphatic filariasis, is a very rare condition that’s spread by mosquitoes the common name is often used because if you have it, your arms and legs can swell and.
