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.

摘要

隐孢子虫属、贾第虫属和结肠小袋纤毛虫是重要的腹泻病原体，分布于全球，威胁着人类和动物的健康。尽管牛是这些原生动物的潜在传播宿主，但对公共卫生的相关风险却被忽视了。在本研究中，从黑龙江省13个行政区共采集了1155份牛粪样本。隐孢子虫属、贾第虫属和结肠小袋纤毛虫的感染率分别为5.5%（64/1155；95%置信区间：4.2 - 6.9）、3.8%（44/1155；95%置信区间：2.7 - 4.9）和6.5%（75/1155；95%置信区间：5.1 - 7.9）。在这些阳性粪便样本中，鉴定出了5种隐孢子虫（微小隐孢子虫、安氏隐孢子虫、牛隐孢子虫、鼠隐孢子虫和猪隐孢子虫）、2个贾第虫组合（E和A）以及8个结肠小袋纤毛虫基因型（BEB4、BEB6、BEB8、J、I、CHS7、CHS8和COS - I）。系统发育分析表明，本研究中鉴定出的所有8个结肠小袋纤毛虫基因型都属于第2组。值得注意的是，这些肠道原生动物的一些物种/基因型是人畜共患的，这表明在流行地区存在人畜共患病传播的风险。这些发现扩展了我们对黑龙江省牛体内隐孢子虫属、贾第虫属和结肠小袋纤毛虫的遗传组成和人畜共患潜力的认识。
