Abstract

Giardia duodenalis is a zoonotic protozoan parasite that causes diarrhea through waterborne transmission or fecal-oral infection. The cysts are chlorine-resistant and, therefore, can pollute drinking water and induce a pandemic disease. In this study, we aimed to detect G. duodenalis infection in stray dogs in Hualien, Taiwan. We collected faecal samples from 118 dogs and amplified DNA sequences of the β-giardin gene by nested polymerase chain reactions (nested PCR). Eleven of the 118 faecal samples tested positive for the parasite. The genotype analysis of the 11 samples indicated that 7 samples belonged to assemblage C and four samples belonged to assemblage D. Our study provided a better understanding of the infection rate and genotypes of G. duodenalis in dogs from Hualien City, and human infection could not be induced by this zoonotic infection pathway in Hualien City.
