N1 - Funding Information:
We thank the shopkeepers for providing the samples from poultry. We are also very grateful to the staff members of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh for collaborating with us. This study was funded by grants-in-aid for Scientific Research (B) and (C) and Scientific Research on Innovative Areas (3805) from the Ministry of Education, Culture, Science, Sports, and Technology (MEXT) of Japan; and by the Livestock Promotional Subsidy from the Japan Racing Association.

N2 - Cryptosporidium is an opportunistic parasite that has been reported in >30 avian hosts worldwide, however, there is no information regarding Cryptosporidium spp. in poultry in Bangladesh. Accordingly, we investigated the prevalence of Cryptosporidium spp. in poultry at open live bird markets in Bangladesh. A total of 197 samples were randomly collected from poultry at open live bird markets in Bangladesh and screened for the detection of Cryptosporidium. Initial microscopic examination revealed Cryptosporidium spp. was observed in 19.8% (39/197) of the poultry specimens. Subsequent nested PCR targeting the 18S rRNA gene revealed that 15.7% (31/197) of the samples were Cryptosporidium positive. Of these 31 samples, 17 were Cryptosporidium baileyi (8.7%), 12 were Cryptosporidium meleagridis (6.0%), and 2 were Cryptosporidium parvum (1.0%). Nucleotide sequence analysis of the GP60 gene of the C. meleagridis revealed that two subtypes (IIIbA21G1R1 and IIIbA23G1R1), which were found in broiler, native and sonali chickens and a pigeon, matched those previously reported in humans and poultry. We identified two novel subtypes (IIIbA21G2R1 and IIIbA20G2R1) in sonali chickens, a broiler chicken and a layer chicken. We also amplified the GP60 gene of C. parvum and found two subtypes (IIaA11G2R1 and IIaA13G2R1) in a sonali and a broiler chicken that were previously reported in calf. These findings suggest that poultry can be a source of cryptosporidial infections for humans and animals in Bangladesh. This is the first molecular investigation of Cryptosporidium genotypes and subtypes in poultry at open live bird markets in Bangladesh.
