Molecular phylogenetic analysis of from horses raised in Canada or Japan, using mitochondrial cytochrome gene-targeted PCR.

Alveolar echinococcosis is a zoonotic disease caused by a larval-stage infection. Geographical haplotyping targeting the parasite's mitochondrial cytochrome () gene has been reported for isolates from definitive and intermediate hosts (wild canids and rodents); however, there are limited reports on strain typing for the dead-end host, the horse, which could act as a sentinel for E. Accordingly, we investigated the diversity of in isolates obtained from slaughtered Japanese and Canadian horses originating from the Iburi and Hidaka regions in Hokkaido and from Alberta, respectively, with PCR and haplogroup analyses targeting gene sequences obtained.

Rapid detection of alveolar echinococcosis in hepatic nodules of horses by recombinase polymerase amplification assay.

Alveolar echinococcosis in slaughtered horses remains a public health issue. This study aimed to develop a Recombinase polymerase amplification (RPA) assay targeting the mitochondrial NADH dehydrogenase subunit 5 () gene of for the rapid detection of equine alveolar echinococcosis. Thirty-six hepatic solid nodules obtained from each horse ( = 36) were evaluated based on histopathological examination and -targeted PCR and then submitted to the RPA assay.
