摘要： Enterocytozoon bieneusi is one of the most important causative agents of microsporidiosis, causing diarrhoea the symptoms of enteric disease in humans and animals. Although there is some information on the prevalence and genotypes of E. bieneusi in China, there is still a lack of data in pigs in southern China. In the present study, a total of 396 faecal specimens were collected from pigs in Zhejiang, Guangdong and Yunnan provinces in southern China, and were examined by nested PCR amplification of the ribosomal internal transcribed spacer (ITS) for the prevalence and genotypes of E. bieneusi. The overall prevalence of E. bieneusi in pigs was 31.57% (125/396), forming 15 genotypes, including 9 known genotypes (EbpC, EbpA, D, G, H, PigEBITS5, Henan-IV, KIN-1, CHS5) and 6 novel genotypes (GD1, ZJ1, ZJ2, YN1, YN2 and YN3), which were all clustered into Group 1. Moreover, multilocus sequence typing (MLST) showed that 6, 3, 4 and 5 types were identified in MS1, MS3, MS7 and MS4 loci, respectively, representing four multilocus genotypes (MLGs), designated as MLGs novel-1 to novel-4 in the present study. This is the first detailed study of E. bieneusi using MLST in pigs in southern China, which extended information about the distribution of E. bieneusi genotypes in China.
