Abstract

Echinococcosis, caused by larval stage of the genus Echinococcus, is one of the most important zoonotic diseases worldwide. The purpose of this study was to determine the presence and prevalence of Echinococcus species in stray dogs of Erzurum, a highly endemic region for cystic echinococcosis (CE) and alveolar echinococcosis (AE) in Turkey. The study samples consisted of 446 stray dog faecal specimens collected from an animal shelter in Erzurum, Turkey, between October 2015 and February 2016. The faecal samples were collected from individual dogs for the isolation of taeniid eggs using the sequential sieving and flotation method (SSFM). Molecular analyses and sequencing revealed the prevalence of Echinococcus spp. as 14.13% (63/446) in faecal samples. The stray dogs harboured five different Echinococcus spp.: E. granulosus s.s. (G1/G3) (n = 41), E. equinus (G4) (n = 3), E. ortleppi (G5) (n = 1), E. canadensis (G6/G7) (n = 3) and E. multilocularis (n = 16). E. granulosus s.s. was the most abundant species. Surprisingly, the occurrence of E. multilocularis in dogs was revealed for the first time in Turkey. E. ortleppi was also reported for the first time in Turkey. These findings highlight a significant public health risk for human AE and CE, presenting useful baseline data on Echinococcus spp. infection in dogs for designing control strategies.
