Giardia duodenalis is a protozoan parasite found in humans and several mammals. This parasite spreads worldwide and is generally recognized as a zoonotic agent being reported to be one of the most common causes of diarrhea in humans and animals. In this study, it was aimed to determine the prevalence and genotypes of G. duodenalis in shelter dogs in Diyarbakır province being located in the southeastern Anatolia region of Türkiye. Native-Lugol method and nested polymerase chain reaction analyses of 100 fecal samples showed a prevalence of 3.00 and 4.00%, respectively. The prevalence was higher in females and in those younger than 1 year. Sequence analysis revealed the presence of zoonotic assemblage B, assemblage D and assemblage E. The detection of zoonotic assemblage B in this study suggests that dogs may be a reservoir for human giardiasis. Further molecular research is needed to determine the genotype diversity of Giardia as well as its possible role in the transmission of this parasite to humans.

Giardia duodenalis is a zoonotic protozoan infecting various vertebrates such as humans and domestic animals. The aim of this study was to determine the frequency and genotypes of G. duodenalis using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in dogs of Urmia, Iran. Overall, 246 stool specimens were collected from 100 pet, 49 stray, and 97 shelter dogs in the Urmia, Iran. Totally, seven samples (2.48%) were microscopically positive in terms of Giardia cyst. The PCR-RFLP analysis revealed that three (1.21%) and two (0.83%) samples have the C and D genotypes, respectively. In addition, two samples (0.83%) were belonged to the AI sub-group. A significant association was determined between the frequency of Giardia infection and life style, age, and stool form of dogs. The findings of the study showed the high frequency of Giardia infection in stray dogs and the dogs under one-year-old. Furthermore, the C and D genotypes of G. duodenalis were predominant in dogs of Urmia, Iran.
