摘要

本研究旨在阐明牛隐孢子虫在埃及北部、中部和南部不同省份(如Behera、Menofia、Qaliubiya、Assiut和Sohag)的哺乳和断奶犊牛(Bubalus bubalis)中的流行情况;结果表明，在825份粪便样本中，总感染率为7.27%，其中1月龄以内的犊牛感染率最高(8.2%)，季节差异显著，冬季感染率最高(11.24%)，性别和地区对感染的影响不显著。对当地牛分离物的18SSU-rRNA基因进行测序和系统发育分析，发现牛隐孢子虫基因型与人分离物高度相似，可引起牛分离物人畜共患传播，是埃及人隐孢子虫病的潜在传染源。

Overview on Cryptosporidium bovis and Its Effect on Calves in Some Governorates in Egypt

The present study was conducted to elucidate the prevalence of Cryptosporidium bovis in suckling and weaned cattle calves (Bubalus bubalis) 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 (n = 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 C. bovis 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.
