Seasonal prevalence of onchocerca-like microfilaria in camels in Kuwait

Infection of the camel [Camelus dromedarius] with Onchocerca- like microfilaria is recorded for the first time in Kuwait. Throughout a period of 14 months, the blood of 284 camels were examined, from which 32 were found infected with the microfilaria. Infections were recorded in all months, except during summer [July to September] and February. The highest monthly incidence [27%] was detected in June at end of spring. It was suggested that harsh environmental conditions in Kuwait during summer either arrest development of microfilariae or influence their diurnal distribution in the tissues of the camel

Filariasis in Tak Province, northwest Thailand: the presence of subperiodic variant Wuchereria bancrofti.

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.
