AI Article Synopsis

  • The text discusses the impact of intracellular coccidian protozoans on animals and humans, highlighting that Sarcocystosis in sheep can lead to severe health issues and economic losses in livestock.
  • A study was conducted to check for the prevalence of these protozoans in sheep from Shanxi Province, China, involving the examination of 582 sheep muscle samples.
  • Results revealed that 33.85% of the samples tested positive for the protozoans, with genetic sequencing confirming their identity and marking the first documentation of their prevalence in this region, contributing valuable data for controlling sheep sarcocystosis.

Article Abstract

species are intracellular coccidian protozoans that can infect a range of animals and humans and cause public health problems and economically significant losses. Sarcocystosis in sheep () can cause abortion, neurological symptoms, and even death and results in significant economic losses to the livestock industry. To date, however, it is yet unknown whether sheep in Shanxi Province, north China, are infected with spp. The purpose of this study was to investigate the prevalence of spp. in sheep in Shanxi Province. Thus, 582 muscle samples of sheep were purchased from farmers' markets from ten representative counties in Shanxi Province, north China, and examined for the presence and prevalence of spp. by PCR amplification of the mitochondrial cytochrome c oxidase subunit I (1) gene. Of the examined 582 mutton samples, 197 samples (33.85%) were -positive and were sequenced. Of the obtained 197 1 sequences, 196 sequences showed nucleotide similarity of 98.56-99.81% with those of , and the remaining one 1 sequence showed nucleotide similarity of 99.71% with that of . Two representative 1 sequences of (accession nos. PQ189447 and PQ189448) have 99.52% and 99.61% identity with (KC209725) and (MK419984), respectively. The sequence of (accession no. PQ165949) obtained in this study has 99.71% identity with (MK419975). This present study documents the occurrence and prevalence of spp. in sheep in Shanxi Province for the first time, which enriches the data on the distribution of spp. in sheep in China and has implications for the control of sheep sarcocystosis.
