Giardiasis is considered an important zoonotic disease caused by Giardia duodenalis. However, molecular characterization is necessary to determine the zoonotic potential of G. duodenalis. Assemblages A and B have been known to infect humans and animals, whereas the others are mostly host specific to animals. Giardiasis in dogs and calves is important because of its highly prevalent rate of infection, clinical symptoms, and potential zoonotic risk. The aim of the present research was to investigate the prevalence and molecular characterization of G. duodenalis among dogs and calves in Aegean Region of Turkey. For this purpose, faecal samples from 563 dogs and 211 Holstein calves were collected. After investigating all samples microscopically, Nested-PCR was performed on positive samples. As a result, prevalence of giardiasis in dogs and calves were determined 11.54% and 16.11% respectively. The positive dogs were found to be both B4 and A3 assemblages. on the other hand, calves were positive for A3. in conclusion, the relatively high prevalence of giardiasis and the presence of the potential zoonotic sub-genotypes in dogs and calves remark the importance of treatment and preventative measures.
