Cryptosporidium parasites can infect a wide range of vertebrate hosts including reptiles, mammals, and birds. Due to the zoonotic nature of cryptosporidiosis and its close contact with exotic birds and humans, the present study aimed to determine the prevalence and genetic diversity of Cryptosporidium spp. in exotic birds of southwest of Iran, by the staining and molecular methods. In the present research, 369 stool specimens were randomly collected from exotic birds and stained by modified acid-fast stain using Ziehl-Neelsen method. The slides were examined using light microscopy at a magnification of 100X. Then, the extracted DNA was amplified using the PCR method. Finally, all genotypes and positive samples from PCR assay were sequenced by Bioneer Company (Daejeon, South Korea). Among 369 stool specimens, 25 and 27 cases were found to be positive for Cryptosporidium spp. by the modified Ziehl-Neelsen staining and the PCR methods, respectively. Based on the genotyping, C. avian genotype III and C. meleagridis were detected in 25 and 2 stool samples, respectively. The results revealed a relatively high prevalence of Cryptosporidium spp. in exotic birds in the southwest of Iran. Due to the zoonotic nature of C. meleagridis, these exotic birds can be a significant source of cryptosporidiosis. It is important that high-risk people, including immune-deficient patients, receive correct information about the risk of indirect and direct contact with infected exotic birds.
