Male is more or less similar.
Female is indistinguishable from that of W. bancrofti.
Microfilariae are about 230µm long and 6 µm in diameter.
Sheathed and with kinks in surface unlike W. bancrofti has a smooth surface.
The cephalic space is longer. Double styles are present at the anterior end. The nuclei are blurred, hence counting is difficult. Tail end is not free from nuclei. There are two discrete nuclei—one at the extreme tip of the tail and the other is found midway between the tip and the posterior column of nuclei.
Adult worm is found in the lymphatic system like W. bancrofti.
Similar micofilariae found in man, monkeys, the civet cat and the cat in India and Malaysia. Presbytes monkeys may be the reservoir. The periodic form occurs in India, Sri Lanka, Thailand, Malaysia, Korea and Japan but the sub-periodic form occurs in the east coast of Malaysia, Thailand and the Philippines.
Larval development in mosquito is completed within 6-8 days.
Details of development are same as that of W. bancrofti, except that the caudal papillae of the third stage in the mosquito are two in number.
3rd stage larva enters into the proboscis of mosquito by 6-8 days. This is the infective stage.
Anopheles barbirostris, Mansonia annulifera, M. indi- ana, M. uniformis.
In man the life stages are similar as that of W. bancrofti.
Microfilariae appear in peripheral blood at night time in the case of Anopheles barbirostris.
whereas Adult worms are creamy white, filiform and have cylindrical body with tapering ends. Posterior end of male is sharply curved ventrally bearing two unequal copulatory spicules.
The female has narrow and abruptly pointed tail end.
Microfilariae are 225 to 300 µm long and 10 µm in diameter.
A hyaline sheath projects slightly beyond the extremities of the embryo and this sheath represents the chorionic envelope.
Cuticula is lined by subcuticular cells.
The anterior end is blunt bearing a distinct cephalic space which is devoid of nuclei. A nerve ring is seen near the anterior end, behind which at some distance is excretory pore. Near the posterior end is the anal spot. These areas are also devoid of nuclei. But the rest of the body contains nuclei of cells which are used as definite land marks for the identification of this species.
