Abstract

In the present study, a total of 615 fecal samples from veterinary clinics were screened by microscopy for the presence of Cryptosporidium and Giardia oocysts. Molecular genotyping of Cryptosporidium and Giardia were carried out using PCR and sequence analysis. Overall, Cryptosporidium and Giardia oocysts were detected in the 0.6% (2/315) and 1.9% (6/315) of dogs and in the 0.7% (2/300) and 1.3% (4/300) of cats, respectively. Sequencing revealed the presence of C. canis (n = 2) in dogs and C. felis (n = 2) in cats. Moreover, G. intestinalisassemblage D (n = 2), C (n = 3) and A, sub-assemblage AII (n = 1) were identified in dogs; G. intestinalis assemblage F (n = 3) and assemblage A, sub-assemblage AI (n = 1) were identified in cats. The highest prevalence of Giardia was observed in dogs younger than one year (6/315), and in those with diarrhea (p < 0.05). Data of the study suggest that dogs and cats play a minor role in the zoonotic transmission of cryptosporidiosis and giardiasis in Southwestern Iran.
