Serum samples obtained from 1.537 cattle in the 14 local government areas (LGAs) of Plateau State of Nigeria were screened for the presence of leptospiral antibodies using 13 serovars in a modified microscopic agglutination test (MAT). Two hundred and twenty-two (14.4 p.100) of the cattle tested had leptospiral antibody titres of 1:100 or higher to one or more of the test antigens. The prevalence rates of antibodies to individual serovars were: hardjo (35.6 p.100), pomona (11.7 p.100), pyrogenes (11.7 p.100), canicola (9.5 p.100), grippotyphosa (7.7 p.100), bratislava (5.9 p.100), icterohaemorrhagiae (5.9 p.100), ballum (4.5 p.100), autumnalis (3.6 p.100), bataviae (2.3 p.100) and tarassovi (1.8 p.100). The serological prevalence of bovine leptospirosis in the various local government areas of Plateau State of Nigeria differed significantly (P less than 0.05; X2).
从尼日利亚高原州14个地方政府辖区的1537头牛采集血清样本，采用改良显微镜凝集试验（MAT），使用13个血清型检测钩端螺旋体抗体的存在情况。检测的牛中有222头（14.4%）对一种或多种检测抗原的钩端螺旋体抗体效价达到1:100或更高。针对各个血清型的抗体流行率分别为：哈德乔型（35.6%）、波摩那型（11.7%）、致热型（11.7%）、犬型（9.5%）、七日热型（7.7%）、布拉迪斯拉发型（5.9%）、出血黄疸型（5.9%）、拜伦型（4.5%）、秋季热型（3.6%）、巴达维亚型（2.3%）和塔拉索夫型（1.8%）。尼日利亚高原州各地方政府辖区牛钩端螺旋体病的血清学流行率差异显著（P<0.05；卡方检验）。
