Large-scale survey of Cryptosporidium spp. in chickens and Pekin ducks (Anas platyrhynchos) in Henan, China: prevalence and molecular characterization

Few data are available on the molecular characterization of Cryptosporidium spp. in chickens and ducks in China. In this study, 2579 faecal samples from 46 chicken farms and eight Pekin duck farms in 21 prefectures in Henan Province were examined. The overall infection rate of Cryptosporidium was 10...

Description
Summary:Few data are available on the molecular characterization of Cryptosporidium spp. in chickens and ducks in China. In this study, 2579 faecal samples from 46 chicken farms and eight Pekin duck farms in 21 prefectures in Henan Province were examined. The overall infection rate of Cryptosporidium was 10.6% (163/1542) in layer chickens (10 out of 17 farms), 3.4% (16/473) in broilers (five out of 29 farms), and 16.3% (92/564) in Pekin ducks (four out of eight farms), respectively. The highest infection rates were observed in 31-day-old to 60-day-old layer chickens (24.6%) and 11-day-old to 30-day-old Pekin ducks (40.3%). The season of highest prevalence in chickens was spring (15.6%) and the lowest was winter (P
