Of the 340 dogs, 100(29.4%) were found to be positive for microfilaremia and the density of microfilaria range from 1 to 1800 in the 20 μl of examined. In Keelung a total of 230 dogs was examined for both microfilaria and the adult worms. The number of male, female and inmature worms were also noted. Of the 230 dogs, 50(21.7%) and 101(47.2%) were found to be positive for microfilaremia and adult worms, respectively. A total of 335 female, 331 male and 15 immature was collected. From the statistic analysis of the host data, no significant difference in the prevalence of the infection was observed between male and female dogs, between pure breed and mongrel dogs, between dogs with darker and lighter haircoat color, and between dogs with healthy and diseased skin conditions. Only the age of the host was found to be statistically significan with respect to the pravelence, that is, the older the host, the higher the infection rate.
