Occurrence of gastrointestinal helminths and the first molecular detection of Ancylostoma ceylanicum, Trichuris trichiura, and Trichuris vulpis in dogs in Myanmar.

Abstract

Dogs may serve as hosts for a variety of zoonotic or potentially zoonotic helminths, including Ancylostoma ceylanicum and Trichuris species. Cross-sectional study design was used to collect 210 faecal samples of dogs from Nay Pyi Taw area, Myanmar. According to microscopic examination, 180 samples (85.7%) were positive for eight species of gastrointestinal helminths. Among them, positive rates of Ancylostoma species and Trichuris species eggs were observed as 79.0% (166/210) and 11.9% (15/210), respectively. Molecular identification of A. ceylanicum and Trichuris species was confirmed by COX1 gene- and SSU rRNA gene-targeted PCR. Partial sequences of COX1 and SSU rRNA showed 100% identity with A. ceylanicum, Trichuris trichiura, and Trichuris vulpis deposited in GenBank.
