Leptospirosis is caused by pathogenic bacteria of the genus Leptospira and is one of causative agents of reproductive problems leading to negative economic impact on bovine worldwide. The goal of this study was to investigate the seroprevalence of Leptospira spp. in cattle in some governorates of Egypt's Nile Delta and assess the risk factors for infection. A total of 410 serum samples were collected from cattle and examined using microscopic agglutination test. The overall seroprevalence was 10.2% and the most prevalent serovars were Icterohaemorrhagiae, Pomona and Canicola. In addition, the potential risk factors were associated Leptospira spp. infection were age, herd size, history of abortion, presence of dogs and rodent control. Thus, leptospirosis is common in dairy cattle in the Nile Delta and the presence of rodents in feed and dog-accessible pastures increases the risk of Leptospira spp. infection among animals.
钩端螺旋体病是由钩端螺旋体属的致病菌引起的，是导致全球牛生殖问题的病原体之一，对牛的经济产生负面影响。本研究的目的是调查埃及尼罗河三角洲部分地区牛钩端螺旋体病的血清流行率，并评估感染的危险因素。共采集了 410 份牛血清样本，采用显微镜凝集试验进行检测。总的血清流行率为 10.2%，最流行的血清型为黄疸出血、波蒙那和坎尼卡雷。此外，与钩端螺旋体病感染相关的潜在危险因素包括年龄、畜群规模、流产史、犬只存在和鼠类控制情况。因此，尼罗河三角洲的奶牛中普遍存在钩端螺旋体病，而饲料和犬类可进入的牧场上存在啮齿动物会增加动物感染钩端螺旋体病的风险。
