Background: Few reports of Echinococcus granulosus have been described in the Unites States; however, the geographical distribution of Echinococcus spp. in wild hosts is increasing consequent to human activities.
Methods:We investigated the prevalence of Echinococcus spp. in re-established elk ( Cervus canadensis ) populations in the North Cumberland Wildlife Management Area and the Great Smoky Mountains National Park via a retrospective analysis of banked elk tissues and an examination of intestinal contents from 11 coyotes ( Canis latrans ) from the North Cumberland Wildlife Management Area.
Results: Four elk were PCR and sequence positive for E. canadensis . Each sequence had 98% or greater coverage and identity to multiple E. canadensis genotypes in Genbank. Adult Echinococcus spp. were not detected in any of the coyotes examined in this study.
Conclusions: Continued surveillance of this disease in susceptible species in these areas is warranted, and these data further underscore the risk of zoonotic pathogen introduction secondary to wildlife translocation.
