How will you distinguish microfilaria of wuchereria Bancrofti from that of Brugia malayi?

How will you distinguish microfilaria of wuchereria Bancrofti from that of Brugia malayi?

malayi microfilaria can be found in the blood during the day, while microfilaria of W. bancrofti is found at high levels at night. The time variation in microfilarial levels is known as periodicity.

What is the definitive host of Brugia malayi?

malayi migrate to the proboscis of the mosquito. During the mosquito’s blood meal the larvae enter the wound of the definitive host, which consist of humans, monkeys, domestic cats, and forest carnivores. The larvae then migrate through the subcutaneous tissue to the lymphatic vessels of the definitive host.

What is the vector of brugia timori?

The typical vector for Brugia malayi filariasis are mosquito species from the genera Mansonia and Aedes. During a blood meal, an infected mosquito introduces third-stage filarial larvae onto the skin of the human host, where they penetrate into the bite wound .

What is the reservoir of wuchereria Bancrofti?

RESERVOIR: Humans are the only known reservoir for Wuchereria bancrofti(1). ZOONOSIS: Humans are infected by mosquitoes who act as vectors, as well as a developmental reservoir(1).

What is the meaning of microfilaria?

A microfilaria pertains to the embryonic or early larval stage of a filarial worm or of related genera of the family Onchocercidae. It includes parasitic worms of humans such as those causing filariasis, onchocerciasis, loiasis, etc. The microfilaria develops from the egg.

Which disease is caused by Brugia malayi?

malayi is one of the causative agents of lymphatic filariasis, a condition marked by infection and swelling of the lymphatic system. The disease is primarily caused by the presence of worms in the lymphatic vessels and the resulting inflammatory response of the host.

What causes Brugia malayi?

Lymphatic filariasis is caused by infection with parasites classified as nematodes (roundworms) of the family Filariodidea. There are 3 types of these thread-like filarial worms: Wuchereria bancrofti, which is responsible for 90% of the cases. Brugia malayi, which causes most of the remainder of the cases.

How long do microfilariae live?

The worms can live for approximately 6–8 years and, during their lifetime, produce millions of microfilariae (immature larvae) that circulate in the blood. Mosquitoes are infected with microfilariae by ingesting blood when biting an infected host. Microfilariae mature into infective larvae within the mosquito.
