Which insect causes elephantiasis?
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 become much bigger than they should be. Your sex organs and breasts may also swell up.
What is filariasis caused by?
Filariasis is a rare infectious tropical disorder caused by the round worm parasites (nematode) Wuchereria bancrofti or Brugia malayi. Symptoms result primarily from inflammatory reactions to the adult worms.
What type of mosquito causes filariasis?
Most cases of filariasis are caused by the parasite known as Wuchereria bancrofti. Culex, Aedes and Anopheles mosquitoes serve as vector for W. bancrofti in transmission of the disease. Another parasite called Brugia malayi also causes filariasis is transmitted by the vector Mansonia and Anopheles mosquitoes.
How do filarial worms cause elephantiasis?
malayi is one of two filarial parasites that cause elephantiasis. It spreads from person to person via mosquito bites, which deposit worm larvae into the skin. The parasites wend their way to the body's lymph nodes and vessels, which normally drain fluid from the body's tissues and help to fight infection.
Which disease is caused by nematode?
Nematode infections in humans include ascariasis, trichuriasis, hookworm, enterobiasis, strongyloidiasis, filariasis, trichinosis, dirofilariasis, and angiostrongyliasis (rat lungworm disease), among others.
Which pathogen is responsible for causing malaria?
Malaria is caused by the Plasmodium parasite. The parasite can be spread to humans through the bites of infected mosquitoes. There are many different types of plasmodium parasite, but only 5 types cause malaria in humans.
How do you get strongyloides?
Strongyloidiasis is caused by the parasitic roundworm S. stercoralis. This worm infects mainly humans. Most humans get the infection by coming into contact with contaminated soil.
What does vector borne disease mean?
Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding anthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
What is vector of chikungunya?
Aedes mosquitoes transmit chikungunya virus to people. These types of mosquitoes are found throughout much of the world. Chikungunya virus is transmitted to people through mosquito bites.
What is the difference between Culex and Anopheles mosquito?
Anopheles can be distinguished from Culex by observing their resting posture and wings. Anopheles rests with its body and proboscis making an angle to the surface while Culex rests with its body parallel to the surface but proboscis making an angle to the surface. Rest with body at an angle to the surface.
How does a nematode lead to elephantiasis?
Elephantiasis is a syndrome caused by infection with a nematode parasite called the filarial worm. The parasite is transmitted form human to human via the female mosquito and grows into an adult worm that lives in the lymphatic system of a human.
Where does filariasis occur?
Lymphatic filariasis affects over 120 million people in 72 countries throughout the tropics and sub-tropics of Asia, Africa, the Western Pacific, and parts of the Caribbean and South America. You cannot get infected with the worms in the United States.
What is filarial nematode?
The filariae are thread-like parasitic nematodes (roundworms) that are transmitted by arthropod vectors. The adult worms inhabit specific tissues where they mate and produce microfilariae, the characteristic tiny, thread-like larvae. The microfilariae infect vector arthropods, in which they mature to infective larvae.
