Dirofilaria immitis wild raccoon dog microfilaremia Japan
A surveyof heartworms was made by necropsy examination of sixty-three wild raccoon dogs, which were trapped during 1978-80 in the central area of Japan. Two of them (3.2%) had the heartworms in the right ventricle and the pulmonary arteries. One raccoon dog had 6 worms, 3 females, and another one had 3 worms, 1 male and 2 females. From their morphological findings and measurements, they were identified as Dirofilaria immitis. Body length in total 6 worms was 15.0-17.5 cm in males and 24.2-30.5 cm in females. All of these females had the microfilariae in their uteri. These data indicate that the present worms were well mature, because these measurements are closely similar to those of the adult worms recovered from the dogs. The microfilaremia was observed in both raccoon dogs. In comparison of the microfilariae collected from the raccoon dog with those from the dog and the cat by commonly using the acetone concentration method, the body length of the microfilariae in the raccoon dog is similar to that in the cat rather than that in the dogs.
