 note = {The microfilarial prevalence of Dirofilaria immitis in house dogs in Nagasaki City was examined in spring and autumn in 1968. Of 3370 examined dogs, which were about 18% of the total dogs living in Nagasaki City, 690 dogs, 29.1% were found to have microfilariae. In the dogs under one year no microfilariae were found, but in the one year old dogs microfilarial prevalence was already over 10%, and in the three years or older dogs it ranged mainly between 30 and 40. The mean number of microfilariae per about 20mm^3 blood of positive dogs was 52.3 in spring and 57.9 in autumn. The distribution pattern of the infected dogs in Nagasaki City suggested that more intensive transmission by vector mosquitoes occurred in the suburban districts especially in residential quarters than the urban districts of the City., 熱帯医学 Tropical medicine 12(4). p169-178, 1971},
