Abstract
- Objective: Molecular identification of small cestodes, morphologically consistent with Echinococcus multilocularis , recovered at necropsy from the gastrointestinal tract contents of a red fox, was accomplished by PCR using published species-specific n ad1 primers and methods.<br />Animal: Red fox (Vulpes vulpes) .<br />Procedure: Small cestodes recovered from intestinal contents of a red fox trapped on Prince Edward Island in December 2020 (frozen at -20°C before being processed for parasite recovery in June 2021) were morphologically identified. Species identity confirmation and haplotyping of the cestodes were done via PCR and DNA sequencing of the n ad1, nad2 , and cob genes.<br />Results: Small cestodes morphologically consistent with E. multilocularis were detected in the gastrointestinal tract contents of a red fox trapped near Montague, PEI. The species identity was confirmed via PCR. Haplotyping revealed that they were of the European E1 haplotype.<br />Conclusion: In Canada, E. multilocularis has been reported as far east as Québec, with most reports being in central and western provinces and territories. This is the first report of E. multilocularis infection in a canid host east of Ontario, Canada and illustrates the need for regular wildlife disease surveillance to enhance our understanding of emerging pathogens of veterinary and medical importance.<br />Clinical Relevance: Echinococcus multilocularis is a highly pathogenic zoonotic cestode from the family Taeniidae that can cause alveolar echinococcosis (AE) when rodents, dogs, horses, pigs, non-human primates, or humans ingest its eggs. Alveolar echinococcosis is challenging to treat, and survival rates for untreated individuals are low.<br /> (Copyright and/or publishing rights held by the Canadian Veterinary Medical Association.)
