The objective of the present study was to describe the prevalence and risk factors associated with cryptosporidiosis in buffalo calves in Middle Egypt. During one year, 458 fecal samples were collected from buffalo calves less than 3 month age in 55 small scale herds and examined for the presence of Cryptosporidium oocysts. Data describing age, gender, season, and herd management practices were gathered to assess potential risk factors. Fecal examination showed that 14.19% of the examined calves were positive for Cryptosporidium spp. Calves at 1-15 days were at the highest risk (P < 0.001), and a significant relationship between season and infection (P < 0.05) was recorded. A significant association between infection and hygiene (P < 0.001), type of floor (P < 0.01) and source of water (P < 0.01) was also recorded. Statistical analysis concerning the clinical signs and fecal characteristics revealed a significant association with fecal consistency (P < 0.001), presence of blood (P < 0.01) and mucous (P < 0.01). Moreover, a significant association was found between infection and the desire for suckling (P < 0.05) and tenesmus (P < 0.05). The results of the present study demonstrated the strong relation between infections by Cryptosporidium spp. and diarrhea in buffalo calves.
本研究的目的是描述埃及中部水牛犊隐孢子虫病的患病率及相关危险因素。在一年时间里，从55个小规模牛群中采集了458份3月龄以下水牛犊的粪便样本，检测隐孢子虫卵囊的存在情况。收集了描述年龄、性别、季节和牛群管理方式的数据，以评估潜在的危险因素。粪便检查显示，14.19%的受检犊牛隐孢子虫属检测呈阳性。1至15日龄的犊牛风险最高（P < 0.001），且记录到季节与感染之间存在显著关系（P < 0.05）。感染与卫生状况（P < 0.001）、地面类型（P < 0.01）和水源（P < 0.01）之间也存在显著关联。关于临床症状和粪便特征的统计分析显示，与粪便稠度（P < 0.001）、血液存在情况（P < 0.01）和黏液（P < 0.01）存在显著关联。此外，发现感染与吮乳欲望（P < 0.05）和里急后重（P < 0.05）之间存在显著关联。本研究结果表明，水牛犊隐孢子虫属感染与腹泻之间存在密切关系。
