Because the adult worm may not be detected directly, tests are designed to find microfilaria in the blood stream.

For some species, the developmental fates of individual cells have been followed from the microfilaria stage to the adult worm.

The microfilaria is a miniature adult and retains the egg membrane as a sheath, and is often considered an advanced embryo.
14.
It should be distinguished from " Microfilaria semiclarum " ( a parasite of animals which sometimes causes accidental infections in humans ).

In patients with high microfilaria load, however, treatment with DEC may be contraindicated, as the rapid microfilaricidal actions of the drug can provoke encephalopathy.
16.
While a vaccine does not exist, the use of a periodic medication can prevent the development of microfilaria, thereby preventing the development of an adult worm.
17.
The theory is that the killing of massive numbers of microfilaria, some of which may be near the ocular and brain region, can lead to encephalopathy.

"It takes two things to get this disease _ mosquitoes that are the only carriers of it and dogs that are going to pick up the microfilaria, " she said.

An epidemiological survey was carried out by the then Malaria Institute, now IEDCR, in the greater districts of Dinajpur and Rangpur for both microfilaria in blood and clinical filariasis in 1969-73.

He said there is no simple diagnosis tool till now in our country to diagnose Filariasis at its early stage except microscopic examination of blood for microfilaria collected at night which is very cumbersome, difficult and gives false negative results.
