Prevalence and molecular characterization ofspp. in cattle in central and Western Inner Mongolia, China.

Abstract

spp. are apicomplexan parasites that can cause diarrhea in humans and animals, posing a health risk to both animals and humans. Molecular epidemiological analysis provides essential data for understandingtransmission, treatment, and control. In this study, SSU rRNA was used to determine the prevalence ofin cattle. A total of 847 fecal samples were collected from 16 farms in central and western Inner Mongolia (Hohhot, Ordos, Bayan Nur and Baotou), and 15.94% (135/847) of samples were positive. Overall,was detected in all seasons. Calves up to 2 months of age were found with the highest rate of infection (33.33%). In older animals, there was a significant decline in infection rates with increasing age. The species,( = 105),( = 21) and( = 9) were detected, individually, or in mixed infections involving two or threespp., and five subtypes of(IIdA17G1, IIdA17G2, IIdA18G1, IIdA19G1, IIdA20G1) were identified. Our findings provide data to support the epidemiological control ofinfection in cattle.
