Abstract (opening): <i>Cryptosporidium</i> spp. are common protist pathogens, and the growing popularity of pet rodents raises concerns about their potential role in zoonotic parasites transmission. However, epidemiological data on <i>Cryptosporidium</i> spp. in pet rodents in Yunnan Province is scarce. To examine the occurrence of <i>Cryptosporidium</i> spp. in pet rodents in Yunnan, we collected 762 fecal samples from four rodent species across four cities. Nested PCR and DNA sequencing were used to characterize the species and subtypes of <i>Cryptosporidium</i>. The occurrence of <i>Cryptosporidium</i> spp. in guinea pigs (<i>Cavia porcellus</i>), Siberian dwarf hamsters (<i>Phodopus sungorus</i>), Syrian hamsters (<i>Mesocricetus auratus</i>) and fancy rats (<i>Rattus norvegicus domestica</i>) was 18.7% (80/426), 17.3% (36/207), 12.5% (15/120), 0% (0/9), respectively, with an overall rate of 17.2% (131/762). According to regions, the positivity rate of <i>Cryptosporidium</i> spp. in Zhaotong city, Kunming city, Yuxi city and Qujing city was 21.0%, 17.9%, 16.8% and 10.5%, respectively. In terms of sampling location, the occurrence of <i>Cryptosporidium</i> spp. in pet markets, farms and shops was 19.5%, 18.6% and 0%, respectively. Sequence analysis of the small subunit ribosomal RNA (<i>SSU</i> rRNA) gene identified six <i>Cryptosporidium</i> species/genotypes: <i>Cryptosporidium homai</i> (<i>n</i> = 52), <i>Cryptosporidium wrairi</i> (<i>n</i> = 30), <i>Cryptosporidium</i> sp. hamster genotype (<i>n</i> = 25), <i>Cryptosporidium andersoni</i> (<i>n</i> = 20), <i>Cryptosporidium parvum</i> (<i>n</i> = 5), and <i>Cryptosporidium muris</i> (<i>n</i> = 1). Further subtyping of <i>C. andersoni</i> isolates using multilocus sequence typing (MLST) revealed a single subtype, with all isolates identified as A3A4A2A2. All five <i>C. parvum</i> isolates were identified as subtype IIdA15G1 based on the <i>gp60</i> gene. Our findings demonstrated the presence of the zoonotic <i>C. parvum</i> IIdA15G1 subtype in pet rodents, suggesting that these animals, particularly hamsters, may serve as reservoirs for human-pathogenic <i>Cryptosporidium</i> species. These results underscore the need for improved biosecurity and husbandry practices in the pet rodent trade to mitigate public health risks. *[CC BY — Open Access, verbatim with attribution.]*
