The overall infection rate by <jats:italic>Cryptosporidium<\/jats:italic> spp. was 11.5% (71\/617), and ten of the 18 farms were positive. The infection rate by <jats:italic>Cryptosporidium<\/jats:italic> spp. was 14.5% (48\/331) in the 30\u201360 d group, higher than chickens in the &lt;30\u00a0d (12.0%, 15\/125), 60\u201390 d (6.9%, 5\/72), and &gt;90 d (3.4%, 3\/89) groups. <jats:italic>Cryptosporidium meleagridis<\/jats:italic> (<jats:italic>n<\/jats:italic>\u00a0=\u00a038) and <jats:italic>C. baileyi<\/jats:italic> (<jats:italic>n<\/jats:italic>\u00a0=\u00a033) were confirmed by sequencing analysis. A total of 25 of the 38 <jats:italic>C. meleagridis-<\/jats:italic>positive specimens were subtyped successfully at the <jats:italic>gp60<\/jats:italic> gene, including one known subtype (IIIbA23G1R1, <jats:italic>n<\/jats:italic>\u00a0=\u00a01) and two novel subtypes, named IIIbA25G1R1 (<jats:italic>n<\/jats:italic>\u00a0=\u00a020) and IIIbA31G1R1 (<jats:italic>n<\/jats:italic>\u00a0=\u00a04). The results showed that infection by <jats:italic>Cryptosporidium<\/jats:italic> spp. in Hotan Black Chickens was common in this area and the distribution of <jats:italic>C. meleagridis<\/jats:italic>
