Pigs infected with the zoonotic parasite Trichinella spiralis were detected on a farm in Maryland during an animal welfare investigation. Sera and/or tissues were collected from 49 pigs and three pig carcasses (7 weeks of age to adult, mixed sex). The tissues were tested for the presence of T. spiralis muscle larvae (ML) by tissue digestion, and the sera were tested for the presence of anti-Trichinella antibodies by ELISA. Seventeen of 50 (34%) pigs were infected with T. spiralis based on tissue digestion. Of these 17 pigs, sera were collected from 16; nine were serologically positive, three sera had OD values that were very close to the positive cut-off (0.30), but were still negative, and four were negative (suggesting that they had become infected within a few weeks of testing). All pigs that tested negative by tissue digestion for ML were also ELISA negative. The farm was subsequently depopulated of pigs. Six months later, testing of trapped scavenging mammals in the farm environment demonstrated that 41% were infected with T. spiralis. After 12 months, 10% of trapped animals were T. spiralis positive, and after 18 months, T. spiralis could not be detected in the scavenging mammal population surrounding the farm. Results of the study suggest that T. spiralis, typically transmitted in the peridomestic rat-pig-human cycle in the US, was not maintained in scavenging mammals in the absence of infected pigs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
