Abstract

Background: Trichinellosis is a zoonotic disease with a worldwide distribution. It is caused by several species of nematodes in the genus spp. are transmitted through predation or carrion consumption and occur in domestic and sylvatic cycles. In humans trichinellosis occurs due to the consumption of raw or undercooked, infected meat and is mainly associated with the household slaughter of pigs or the consumption of game animals without veterinary inspection, a cultural practice that is difficult to resolve. Therefore, knowledge of this parasite's reservoir is relevant for better implementing public health strategies. The aim of this study was to assess the presence of sp. in several carnivore and omnivore vertebrates in central-southern Chile.

Methods: We collected muscle tissue from a total of 53 animals from 15 species and were digested to detect larvae which were further identified to species level using molecular techniques.

Results: We detected larvae in (Felidae) and (Mustelidae). We identified the larvae collected from as , but we were unable to molecularly characterize the larvae from . This is the first record of in a native mustelid of South America and the first record of in . This study identified two novel hosts; however, further work is needed to identify the role that these and other hosts play in the cycle of in Chile.
