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.
对来自印度东北部（NER）阿萨姆邦、梅加拉亚邦、米佐拉姆邦的 840 只动物的血清样本进行了钩端螺旋体属抗体的显微镜凝集试验（MAT）检查，以评估动物群中钩端螺旋体病的风险因素和流行情况。并将其与印度南部的泰米尔纳德邦（TN）的血清型和风险因素不一致性进行了比较。在阿萨姆邦，发现鲍勒姆血清型（28.1%）较为普遍，而在泰米尔纳德邦则发现格里波蒂菲萨血清型（16.1%）较为普遍。NER 的总血清阳性率为 36.8%（206/560），而 TN 的总血清阳性率为 30.7%（86/280）。在这项研究中，NER 中猪（42.6%）、牛（39.8%）和山羊（26%）的血清阳性率较高，而 TN 中牛（36.4%）和山羊（17.6%）的血清阳性率较高。在 NER 中，猪群中存在啮齿动物被发现与血清阳性率有显著相关性（P = 0.0088），而在 TN 中，这种相关性则存在于牛群中（P = 0.0063）。我们建议，应在羊群管理实践中纳入控制啮齿动物的方案，以减少钩端螺旋体的传播。
