Mikkonen T Oivanen L Năreaho A Helin H Sukura A Predilection muscles and physical condition of raccoon dogs Nyctereutes procyonoides experimentally infected with Trichinella spiralis and T. nativa. Acta vet. scand. 2001 42 441-452. -The predilection muscles of Trichinella spiralis and T. nativa were studied in 2 experimental groups of 6 raccoon dogs Nyctereutesprocyonoides the third group serving as a control for clinical signs. The infection dose for both parasites was 1 larva g body weight. After 12 weeks the animals were euthanized and 13 sampling sites were analysed by the digestion method. Larvae were found in all sampled skeleton muscles of the infected animals but not in the specimens from the heart or intestinal musculature. Both parasite species reproduced equally well in the raccoon dog. The median density of infection in positive tissues was 353 larvae per gram lpg with T. spiralis and 343 lpg with T. nativa. All the infected animals had the highest larvae numbers in the carpal flexors M. flexor carpi ulnaris . Also tongue and eye muscles had high infection levels. There were no significant differences in the predilection sites between these 2 parasite species. Trichinellosis increased the relative amount of fat but not the body weight in the captive raccoon dogs. Thus Trichinella as a muscle parasite might have catabolic effect on these animals. zoonosis trichinellosis nematode parasite larval distribution symptoms body weight canidae. Introduction The raccoon dog Nyctereutesprocyonoides is a medium sized carnivore about 5-8.5 kg of weight .
