First report of Giardia duodenalis genotypes in Zangxiang pigs from China

Giardia duodenalis is an important zoonotic intestinal protozoan of animals and humans. We collected 450 faecal specimens from four age groups (pre-weaned piglets, weaned piglets, juveniles, adults) of Zangxiang pigs from Shaanxi and Qinghai provinces, to investigate the prevalence and genetic diver...

description Giardia duodenalis is an important zoonotic intestinal protozoan of animals and humans. We collected 450 faecal specimens from four age groups (pre-weaned piglets, weaned piglets, juveniles, adults) of Zangxiang pigs from Shaanxi and Qinghai provinces, to investigate the prevalence and genetic diversity of G. duodenalis at the β-giardin ( bg ), triosephosphate isomerase ( tpi ) and glutamate dehydrogenase ( gdh ) loci using nested PCRs in the present study. A total of 28 faecal samples were positive for presence of G. duodenalis , with an overall prevalence of 6.2%. Giardia duodenalis was detected in pigs from all age groups and in both investigated provinces. Significant differences ( P
