Abstract

Background: We aimed to determine the prevalence of Giardia intestinalis and Cryptosporidium spp. in patients who admitted hospital with diarrhea and to gain information about the transmission of these parasites in Ağrı, Türkiye. Methods: This study included 184 patients who applied to Ağrı-Diyadin State Hospital, Türkiye in 2022. The immunochromatographic card test was used for detection of the G. intestinalis and Cryptosporidium spp. Nested PCR-RFLP analysis of the COWP gene and sequence analysis of the gp60 gene were used to genotype and subtype Cryptosporidium spp., whereas Nested PCR and sequence analyses of β-giardin gene were used genotype G. intestinalis. Results: Of the 184 stool specimens examined, 12 (14.29%) and 7 (3.80%) were positive for G. intestinalis and Cryptosporidium spp., respectively. The Cryptosporidium species were identified as C. parvum belonging to the IId sub-type family. The G. intestinalis were identified assemblages A. Conclusion: Assemblage A, which is associated with diarrhea, is responsible for giardiasis and C. parvum IId subtype, often found in sheep, goats and cattle, is responsible for cryptosporidiosis in Ağrı, Türkiye.
