To clarify Dirofilaria immitis infection among cats in Saitama Prefecture, Japan, 1,840 cats were examined postmortem for adult worms and microfilariae in the blood from 1989 to 1995. As a reference control, 500 dogs from the same area were examined in the same way and period. D. immitis worms were found in 15 cats, one of which had microfilariae in the blood. Prevalence rate of D. immitis infection was 0.8% (15/1,840) in cats and 46.8% (234/500) in dogs examined, whereas it was 4.1% and 64.6% in cats and dogs, respectively, aged 2 years and over. Worm burden per positive cat was 1.5 +/- 0.7 (mean +/- SD), the maximum number of worm was 3 in 2 cats, and 10 cats had a single worm each. All the worm-positive cats were tested for antibodies to feline immunodeficiency virus (FIV) and antigens of feline leukemia virus (FeLV) in sera. Positive rates of coinfection with D. immitis were 26.7% and 13.3% for FIV and FeLV, respectively.
为明确日本埼玉县猫体内的犬恶丝虫感染情况，1989年至1995年期间，对1840只猫进行了死后检查，以检测成虫和血液中的微丝蚴。作为参考对照，同期对同一地区的500只狗进行了同样的检查。在15只猫体内发现了犬恶丝虫，其中1只猫血液中有微丝蚴。在所检查的猫中，犬恶丝虫感染率为0.8%（15/1840），狗的感染率为46.8%（234/500），而2岁及以上猫和狗的感染率分别为4.1%和64.6%。每只阳性猫的虫负荷为1.5±0.7（平均值±标准差），2只猫体内的虫数量最多为3条，10只猫各有1条虫。对所有虫阳性猫的血清进行了猫免疫缺陷病毒（FIV）抗体和猫白血病病毒（FeLV）抗原检测。FIV和FeLV与犬恶丝虫合并感染的阳性率分别为26.7%和13.3%。
