Image Comments:

Infection with the Wucheria bancrofti is endemic in the Eye Clinic patient-population. The microfilariae are transmitted from the heavy mosquito population to the heavy easily bitten human population of the area. When a mosquito sucks blood from an already infected person, it withdraws with the blood a number of filaria embryo. These then undergo stages of development in the body of the mosquito. Finally, these larvae ( microfilariae ) reach the proboscis of the mosquito and are injected into the next victim of that mosquito's unfriendly bite.
