ABSTRACT
A preliminary survey for Bancroftian filariasis in villagers of Ban Prabat Heuy Tom, Tambol Na-Sai, Amphoe Li, Lamphun Province was performed between July 12, 1986 and March 19, 1987. A total of 1,435 villagers comprising 668 females and 767 males were examined for microfilaraemia in peripheral blood. Microfilariae were found in five males of which two cases were found to have developed hydrocele at a lesser degree and all of them had formerly resided in an endemic area of Tak Province. Microfilarial periodicity was studied in two cases, and it was shown to be nocturnally subperiodic.

The microfilariae found in carriers at Tak Province, Northwestern Thailand were morphologically and morphometrically studied. It was found that the parasites conformed to that of W. bancrofti microfilaria. The microfilarial periodicity as determined from four carriers was found to be nocturnally (early evening) subperiodic type showing a distinct peak at 1800 hours.
