The present study was conducted to elucidate the prevalence of in suckling and weaned cattle calves () from different governorates in northern, middle, and southern Egypt, such as Behera, Menofia, Qaliubiya, Assiut, and Sohag; result revealed that from the overall examined fecal samples ( = 825), the overall prevalence was 7.27%, the highest significant infection rate was in young suckling calves less than one month (8.2%), and seasonally, winter season has the highest significant level (11.24%), but sex and locality were of no significant effect on the prevalence of infection in this study. Gene sequencing and phylogenetic analysis of the 18SSU-rRNA gene of the local bovine isolate were performed, and it was found that genotype was highly similar to human isolate, which provoke the zoonotic transmission of bovine isolate to humans and identified as a potential source for human cryptosporidiosis infection in Egypt.
本研究旨在阐明埃及北部、中部和南部不同省份（如贝赫拉、米努夫、盖勒尤比、阿斯尤特和索哈杰）哺乳和断奶牛犊中的患病率；结果显示，在总共检测的粪便样本（n = 825）中，总体患病率为7.27%，最高感染率出现在小于1个月的幼龄哺乳犊牛中（8.2%），按季节来看，冬季的感染率最高（11.24%），但在本研究中，性别和地区对感染患病率没有显著影响。对本地牛分离株的18SSU - rRNA基因进行了基因测序和系统发育分析，发现该基因型与人类分离株高度相似，这引发了牛分离株向人类的人畜共患病传播，并被确定为埃及人类隐孢子虫病感染的潜在来源。
