Serum samples from 840 animals were examined for Leptospira spp. antibodies by microscopic agglutination test (MAT) to assess the risk factors and the prevalence of leptospirosis among animal herds of Assam, Meghalaya, Mizoram the north eastern (NER) provinces. They were compared with Tamilnadu (TN) the southern province of India for the serovar and risk factor inconsistency. Serovar Ballum was reported to be prevalent (28.1 %) in Assam and Grippotyphosa (16.1 %) in Tamilnadu. The overall seropositivity observed was 36.8 %(206/560) from NER and 30.7 %(86/280) from TN. In this study, the higher seroprevalence was observed in pigs (42.6 %), cattle (39.8 %) and goats (26 %) in NER. Cattle (36.4 %) and goat (17.6 %) showed higher prevalence in TN. The presence of rodents in pig herds was found to be significant (P = 0.0088) in NER and it was for cattle in TN (P = 0.0063). We suggest that a program of rodent control should be included in the flock management practices aiming to reduce transmission of the leptospires.

检查了 840 只动物的血清样本中的钩端螺旋体属 通过显微镜凝集试验 (MAT) 检测抗体，以评估东北部 (NER) 省阿萨姆邦、梅加拉亚邦、米佐拉姆邦动物群中钩端螺旋体病的危险因素和流行率。他们与印度南部省份泰米尔纳德邦 (TN) 的血清型和危险因素不一致进行了比较。据报道，Serovar Ballum 在泰米尔纳德邦的阿萨姆邦和 Grippotyphosa（16.1%）流行（28.1%）。观察到的总体血清阳性率为 36.8 % (206/560) 来自 NER 和 30.7 % (86/280) 来自 TN。在这项研究中，在 NER 的猪 (42.6%)、牛 (39.8%) 和山羊 (26%) 中观察到更高的血清阳性率。牛 (36.4%) 和山羊 (17.6%) 在 TN 中的患病率更高。发现 NER 中猪群中啮齿动物的存在是显着的（P = 0.0088），TN 中的牛（P = 0.0063）也是如此。
