Nonencapsulated larvae of Trichinella pseudospiralis were detected in meat and muscle biopsy specimens.
Until 1995, Trichinella pseudospiralis, a nonencapsulating species of the genus Trichinella and the only species that infects both mammals and birds, was not considered a potential pathogen of humans and domestic animals, since it had been detected only in sylvatic animals (raccoon dog, corsac fox, tiger cat, tawny eagle, and rook) in remote regions (Caucasus, Kazakhstan, Tasmania) (1).
