a positive attraction, chemical or otherwise, exerted by the Malpighian tubes of the mosquito upon the microfilaria) of dogs. Yamada and Yamamoto (1916) considered that the condition could be ascribed to oxygen chemotaxis, and Suganuma (1921) that the most important cause of periodicity was the strong negative heliotropism of the embryo. The last author showed that microfilariae were positively...

Entomological and epidemiological data of Lymphatic Filariasis (LF) was collected from 120 villages of four districts of Andhra Pradesh, India. Self-Organising Maps (SOMs), data-mining techniques, was used to classify and prioritise the endemic zones of filariasis. The results show that, SOMs classified all the villages into three major clusters by considering the data of Microfilaria (MF) rate...

BACKGROUND There is very limited data available on the prevalence of Bancroftian filariasis in the Federated States of Micronesia (FSM). Considerable attempts to eliminate the disease had occurred in the Pacific region by the year 2003, and the prevalence in FSM was thought to be sufficiently low that the region was considered non-endemic. However, a survey conducted in 2003 on an isolated atol...
