Abstract:
To characterize the prevalence and species/genotypes of Cryptosporidium spp. in farmed pigs in the north of the Yangtze River in Anhui Province.A total of 500 samples of pig feces were obtained from seven largescale pig farms in the north of the Yangtze River in Anhui Province. PCR and sequences analysis of the small subunit rDNA gene were used to detect and identify the Cryptosporidium species/genotypes.The overall prevalence of Cryptosporidium was 4.8% (24/500). Additionally, Cryptosporidium prevalence was 40.0% in Qianshan and 6.3% in Chuzhou, respectively. No Cryptosporidium infection was found in other sampling areas. The DNA sequence analysis of the SSUrDNA gene revealed that all of the isolates represented C. scrofarum. The Cryptosporidium infection rate (9.1%) of pigs (> 60 days) was significantly higher than the rates of both pigs (< 30 days) and pigs (30–60 days) (both P < 0.01).C. scrofarum in the farmed pigs in the north of the Yangtze River in Anhui Province may be a source of Cryptosporidium infection and pose a potential public health threat to humans and other animals, and therefore, the status should be paid more attention to.
