AI Article Synopsis

  • The study investigates the prevalence of important diarrheal protozoan pathogens in cattle fecal samples collected from Heilongjiang Province, highlighting their global health risks to humans and animals.
  • The research sampled 1,155 cattle, revealing infection rates of 5.5% for one protozoan species, 3.8% for another, and 6.5% for a third, with several genetic variants identified among them.
  • Findings indicate that some protozoan species are zoonotic, meaning they can be transmitted from animals to humans, which raises public health concerns in the affected areas.

Article Abstract

spp., , and are important diarrheal pathogens with a global distribution that threatens the health of humans and animals. Despite cattle being potential transmission hosts of these protozoans, the associated risks to public health have been neglected. In the present study, a total of 1155 cattle fecal samples were collected from 13 administrative regions of Heilongjiang Province. The prevalence of spp., , and were 5.5% (64/1155; 95% CI: 4.2-6.9), 3.8% (44/1155; 95% CI: 2.7-4.9), and 6.5% (75/1155; 95% CI: 5.1-7.9), respectively. Among these positive fecal samples, five species (, , , , and ), two assemblages (E and A), and eight genotypes (BEB4, BEB6, BEB8, J, I, CHS7, CHS8, and COS-I) were identified. Phylogenetic analysis showed that all eight genotypes of identified in the present study belonged to group 2. It is worth noting that some species/genotypes of these intestinal protozoans are zoonotic, suggesting a risk of zoonotic disease transmission in endemic areas. The findings expanded our understanding of the genetic composition and zoonotic potential of spp., , and in cattle in Heilongjiang Province.
