چکیده

Background: parasites of the genus trichinella are zoonotic nematodes common in carnivores throughout the world. we determined the prevalence and species of trichinella infections in florida panthers (puma concolor coryi). methods: tongues from florida panthers were collected at necropsy and examined by pepsin-hcl artificial digestion for infection with trichinella spp. dna was extracted from larvae and multiplex pcr using trichinella species-specific primers was used to genotype the worms. results: trichinella spp. larvae were detected in 24 of 112 (21.4%; 14.6%-30.3%) panthers. sixteen of the panthers (14.3%) were infected with t. pseudospiralis,1 (0.9%) was infected with t. spiralis,and 2 (1.8%) had mixed infections of t. pseudospiralis and t. spiralis. trichinella spp. larvae from 5 panthers were not identified at the species level due to degraded dna. conclusions: this is the highest prevalence of t. pseudospiralis detected in north america up to now and suggests the florida panther is a key mammalian reservoir of this parasite in southern florida. trichinella pseudospiralis can infect both mammals and birds indicating the source of infection for florida panthers could be broader than believed; however,birds represent a small percentage (0.01%) of the cat's diet. since wild pigs (sus scrofa) can be parasitized by both t. pseudospiralis and t. spiralis and these swine can comprise a large portion (∼40%) of a panther's diet in florida,we believe that florida panthers acquired these zoonotic parasites from feeding on wild pigs. © 2015 reichard et al.; licensee biomed central.
