Cryptosporidium is a ubiquitous protozoan in human and animals. To investigate the genetic diversity of Cryptosporidium spp. in alpaca (Vicugna pacos) in China, 484 fecal samples from alpacas were collected at nine sites, and Cryptosporidium spp. were screened with PCR amplification of the small subunit ribosome RNA (SSU rRNA) locus. Cryptosporidium spp. infected 2.9% (14/484) of the alpacas. Of the nine collection sites, two were positive for Cryptosporidium, Wensu (3.0%, 3/100) and Qinghe (31.4%, 11/35). Three Cryptosporidium species were identified: C. parvum (n = 2), C. ubiquitum (n = 1), and C. occultus (n = 11). Cryptosporidium parvum and C. ubiquitum were further subtyped with the 60-kDa glycoprotein locus (gp60). The two C. parvum isolates were subtype IIdA15G1, but the one C. ubiquitum isolate was not subtyped successfully. A phylogenetic analysis indicated that the Cryptosporidium isolates clustered with previously identified species. To our knowledge, this is the first report of Cryptosporidium infections in alpacas in China and provides baseline data for the study of Cryptosporidium in alpacas in China.
