The ocurrence of trichinellosis in wild carnivores and their role in the epizootology and epiodemiology of the disease was studied. In the period 1995-2000, 78 foxes, 45 jackals, 18 wolves, 21 martens, 16 wild cats, 6 badgers and 2 otters, shot in different regions of the mountains East Stara Planina and Sredna Gora, were necropsized. Twenty-four pieces from crura diaphragmatica obtained from each animal, were studied through trichinelloscopy. The highest extensity of invasion (EI) was found out in martens. From all 21 martens, 13 (61.9%) were invaded by trichinellae. The positive results for the other wild animal species were as followed: 42.3% for foxes; 33.3% for jackals; 22.2% for wolves, 31.3% for wild cats and 33.3% for badgers. No trichinellae were present in the muscle samples taken from otters.
