Abstract
During a survey for Sarcocystis infections in Pennsylvania in wild canids, muscles from the tongue and limb were examined microscopically for sarcocysts. Between 9 February 2024 and 11 February 2024, muscle samples were collected from 76 coyotes, 46 gray foxes, and 21 red foxes from Pennsylvania hunter harvested animals. Around 5 g of muscle was examined microscopically by compression between a glass slide and coverslip. Trichinella murrelli larvae were detected in 1 of 76 coyotes (Canis latrans), 1 of 46 gray foxes (Urocyon cinereoargenteus), and in 7 of 21 red foxes (Vulpes vulpes) muscles. Diet and individual host susceptibility probably contributed to the differences in prevalence of T. murrelli in these hosts. This is the first report of Trichinella infection in coyotes from Pennsylvania. The reasons for differences in Trichinella species could be due to inherent susceptibility or the area sampled.
期刊介绍：
The Journal of Parasitology is the official peer-reviewed journal of the American Society of Parasitologists (ASP). The journal publishes original research covering helminths, protozoa, and other parasitic organisms and serves scientific professionals in microbiology, immunology, veterinary science, pathology, and public health. Journal content includes original research articles, brief research notes, announcements of the Society, and book reviews. Articles are subdivided by topic for ease of reference and range from behavior and pathogenesis to systematics and epidemiology. The journal is published continuously online with one full volume printed at the end of each year.
