Abstract

The prevalence of Leptospira interrogans serovars in dairy cattle was determined by analyzing 464 serum samples from cows on 15 properties in Garanhuns municipal district, Pernambuco State, Brazil. A microscopic seroagglutination test including 12 serovars of Leptospira interrogans as antigens was used. Samples with titres 100 were considered positive. Two hundred and twenty-one (47.63%) of the samples were positive to one or more serovars. The prevalence of the serovars was hardjo (21.98%), bratislava (15.73%), castellonis (11.64%), tarassovi (10.56%), pyrogenes (1.72%), icterohaemorrhagiae (1.08%), pomona (0.86%), wolffi (0.86%), grippotyphosa (0.86%), djasiman (0.43%), canicola (0.21 %), and copenhageni (0.21%).

摘要

通过分析巴西伯南布哥州加兰洪斯市辖区15个养殖场奶牛的464份血清样本，确定了问号钩端螺旋体血清型在奶牛中的流行情况。采用了一种显微镜凝集试验，该试验使用12种问号钩端螺旋体血清型作为抗原。滴度≥100的样本被视为阳性。221份（47.63%）样本对一种或多种血清型呈阳性。血清型的流行率分别为：哈德乔型（21.98%）、布拉迪斯拉发型（15.73%）、卡斯泰洛尼型（11.64%）、塔拉索夫型（10.56%）、热解型（1.72%）、出血黄疸型（1.08%）、波摩那型（0.86%）、沃尔夫型（0.86%）、七日热型（0.86%）、雅西曼型（0.43%）、犬型（0.21%）和哥本哈根型（0.21%）。
