Prevalence and Molecular Characterization of Giardia duodenalis Assemblage D of Dogs in Egypt, and Its Zoonotic Implication

Background, Methods: To elucidate the prevalence and molecular characterization of Giardia infection in dogs, a cross-sectional study was performed on stray housed dogs from different localities Egypt. Results: A total 986 fecal specimens were collected dogs. The overall rate 8.5%. diarrheic revealed higher 14.43% than asymptomatic animals. more prevalent younger ( < 6 months) (9.5%) compared to older Higher observed during cold winter months (11.24%). community owned (stray street) showed (11.75%) pet household environment (5.59%). Moreover, it found that fed undercooked meat, offal's showing giardiasis canned meat. On other hand, subjected regular grooming good hygienic practices had lesser unclean neglected Conclusions: sequencing phylogenetic analysis amplicons 18SrRNA gene G. duodenalis that; they closer assemblage D necessitating urgent attention due their zoonotic importance.
