Detection and genetic characterization of Giardia duodenalis in pigs from large-scale farms in Xinjiang, China

To study the presence of Giardia duodenalis in Xinjiang, northwest China, we collected 801 fecal specimens from seven large-scale pig farms and screened them using PCR targeting the SSU rRNA gene. Twenty-one (2.6%) of the specimens from five farms were G. duodenalis-positive, with a significant diff...

Twenty-one (2.6%) of the specimens from five farms were G. duodenalis-positive, with a significant difference in prevalence among different farms (0–8.7%) (p < 0.01). Giardia duodenalis prevalence was highest in fattening pigs (5.4%, 7/129), followed by sows (3.2%, 7/222), post-weaning piglets (1.8%, 5/281), and pre-weaning piglets (1.2%, 2/169), but there was no significant difference in prevalence among the age groups (p < 0.05). Sequence analysis of the SSU rRNA gene revealed that the 21 G. duodenalis strains belonged to three assemblages: A (n = 2), B (n = 16), and E (n = 3). Assemblage B was the predominant assemblage and was widely distributed in all G. duodenalis-positive farms and age groups. All G. duodenalis-positive specimens were further assayed at the β-giardin (bg), glutamate dehydrogenase (gdh), and triosephosphate isomerase (tpi) genes, and two tpi, four gdh, and two bg sequences were identified. These data indicate that pigs may be a zoonotic risk and can potentially spread G. duodenalis infection from animals to humans.

Assemblage B was the predominant assemblage and was widely distributed in all G. duodenalis-positive farms and age groups. All G. duodenalis-positive specimens were further assayed at the β-giardin (bg), glutamate dehydrogenase (gdh), and triosephosphate isomerase (tpi) genes, and two tpi, four gdh, and two bg sequences were identified. These data indicate that pigs may be a zoonotic risk and can potentially spread G. duodenalis infection from animals to humans.

abstract	To study the presence of Giardia duodenalis in Xinjiang, northwest China, we collected 801 fecal specimens from seven large-scale pig farms and screened them using PCR targeting the SSU rRNA gene. Twenty-one (2.6%) of the specimens from five farms were G. duodenalis-positive, with a significant difference in prevalence among different farms (0–8.7%) (p < 0.01). Giardia duodenalis prevalence was highest in fattening pigs (5.4%, 7/129), followed by sows (3.2%, 7/222), post-weaning piglets (1.8%, 5/281), and pre-weaning piglets (1.2%, 2/169), but there was no significant difference in prevalence among the age groups (p < 0.05). Sequence analysis of the SSU rRNA gene revealed that the 21 G. duodenalis strains belonged to three assemblages: A (n = 2), B (n = 16), and E (n = 3). Assemblage B was the predominant assemblage and was widely distributed in all G. duodenalis-positive farms and age groups. All G. duodenalis-positive specimens were further assayed at the β-giardin (bg), glutamate dehydrogenase (gdh), and triosephosphate isomerase (tpi) genes, and two tpi, four gdh, and two bg sequences were identified. These data indicate that pigs may be a zoonotic risk and can potentially spread G. duodenalis infection from animals to humans.

Twenty-one (2.6%) of the specimens from five farms were G. duodenalis-positive, with a significant difference in prevalence among different farms (0–8.7%) (p < 0.01). Giardia duodenalis prevalence was highest in fattening pigs (5.4%, 7/129), followed by sows (3.2%, 7/222), post-weaning piglets (1.8%, 5/281), and pre-weaning piglets (1.2%, 2/169), but there was no significant difference in prevalence among the age groups (p < 0.05). Sequence analysis of the SSU rRNA gene revealed that the 21 G. duodenalis strains belonged to three assemblages: A (n = 2), B (n = 16), and E (n = 3). Assemblage B was the predominant assemblage and was widely distributed in all G. duodenalis-positive farms and age groups. All G. duodenalis-positive specimens were further assayed at the β-giardin (bg), glutamate dehydrogenase (gdh), and triosephosphate isomerase (tpi) genes, and two tpi, four gdh, and two bg sequences were identified. These data indicate that pigs may be a zoonotic risk and can potentially spread G. duodenalis infection from animals to humans.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield
