What is wuchereria bancrofti ?

Ilariasis (philariasis) is a parasitic disease (usually an infectious tropical disease) that is caused by thread-like nematodes (roundworms) belonging to the superfamily Filarioidea, [1] also known as "filariae". [2] These are transmitted from host to host by blood-feeding arthropods, mainly black flies and mosquitoes.

Eight known filarial nematodes use humans as their definitive hosts. These are divided into three groups according to the niche within the body they occupy: 'lymphatic filariasis', 'subcutaneous filariasis', and 'serous cavity filariasis'.

Lymphatic filariasis is caused by the worms Wuchereria bancrofti, Brugia malayi, and Brugia timori. These worms occupy the lymphatic system, including the lymph nodes, and in chronic cases these worms lead to the disease elephantiasis.

Subcutaneous filariasis is caused by Loa loa (the eye worm) , Mansonella streptocerca, and Onchocerca volvulus. These worms occupy the subcutaneous layer of the skin, in the fat layer. L. Loa causes Loa loa filariasis while O. Volvulus causes river blindness.

Serous cavity filariasis is caused by the worms Mansonella perstans and Mansonella ozzardi, which occupy the serous cavity of the abdomen.

The adult worms, which usually stay in one tissue, release early larvae forms known as microfilariae into the host's bloodstream. These circulating microfilariae can be taken up with a blood meal by the arthropod vector; in the vector they develop into infective larvae that can be transmitted to a new host.

Individuals infected by filarial worms may be described as either "microfilaraemic" or "amicrofilaraemic", depending on whether or not microfilaria can be found in their peripheral blood. Filariasis is diagnosed in microfilaraemic cases primarily through direct observation of microfilaria in the peripheral blood. Occult filariasis is diagnosed in amicrofilaraemic cases based on clinical observations and, in some cases, by finding a circulating antigen in the blood.

Actually it is caused by wuchereria. It is transmitted by culex mosquito.

It is caused by roundworms and get transmitted from one infected person to another by mosquitoes.

Filariasis/Filaria is caused by the worms Wuchereria bancrofti, Brugia malayi, and Brugia timori, which fall under PROTOZOA category and Culex Mosquitoes are transporter of the worm from one human to another just like the Malaria. Hence Protozoa is the correct answer in this question.

Filaria is a parasitic disease [ usually an infectious tropical disease ] that is caused by thread - like nematodes [roundworms] belonging to the super family FILARIOIDEA also known as filarae.

Can anyone tell me that who cause the filaria how it is transmitted?

What is the right answer?

See sundar. If a man kills the dog with a knife. Then the man was the one to kill. The knife was just an instrument. If mosquitoes are transmitting it, the worms are the culprit. The are the one who give birth to this disease. This is the answer to your question. Have a good day!

Please correct this answer. It is caused by helminth-worm. Mosquito is only carrier.
