A field examination on the microfilarial prevalence of Dirofilaria immitis among house dogs was carried out in Omura City, Nagasaki Prefecture, in April and October of 1973. Of 908 dogs examined, which were about 39% of the total dogs living in the City, 392 dogs, 43.2%, were found to have microfilariae in their peripheral blood. In the dogs under one-year-old, the microfilarial prevalence was already over 10%; the prevalence reached 41% in the two-year-old dogs and ranged from 42% to 79% in the older ones. The mean number of microfilariae per about 20mm^3 blood of positive dogs was more numerous in males than in females. The spatial distribution of the infected dogs within Omura City suggested that the mosquito vectors transmit D. immitis more intensively in the suburban districts than in the urban or rural districts in the City.
