摘要

Giardia duodenalis is a common intestinal parasite in humans and other mammals, and it causes major public and veterinary health problems worldwide. China is a major pig-raising country, and studies on Giardia in pigs have important public health significance. The present study was conducted to investigate the prevalence of Giardia and assess its genetic characterization. A total of 93 samples were collected from two farms in Shanghai. The presence of Giardia was determined using PCR and sequence analysis of glutamate dehydrogenase, beta-giardin and triose phosphate isomerase genes. The average prevalence of G. duodenalis infection was 26.88% (25/93) in the pigs, with 28.13% (18/64) in farm 1 vs 24.14% (7/29) in farm 2. All the PCR-positive products were successfully sequenced, and assemblage E was more prevalent. Zoonotic assemblages A and B and canine-specific assemblage C were identified in farm 1, whereas, only assemblage E was detected in farm 2. Interestingly, two pig isolates showed 100% homology with human-derived isolates from Australia and China at the bg and tpi loci respectively. Pigs infected with Giardia infect humans by polluting the environment; whether pigs are a potential environmental source of the human pathogen in China requires more epidemiological data.

Duodenalis感染的平均患病率为26.88％（25/93），在农场1 vs 24.14％（7/29）中，28.13％（18/64）。所有PCR阳性产物都是成功测序，并且组合e更为普遍。在农场1中鉴定了Zoonotic AdderBlage A和B和犬特异性组合C，而在农场中只检测到组装E 2.有趣的是，有趣的是，两只猪分离物与来自澳大利亚和中国的人源性分离株显示了100％的同源性。 TPI基因座分别。通过污染环境感染贾迪亚感染了人类的猪;猪是否是中国人类病原体的潜在环境来源需要更多的流行病学数据。
