Two hundred and sixty five subjects with high risk works for leptospirosis were submitted to microscopic agglutination test for leptospira. 122 worked at animal farms, 71 in rice growing fields and 72 in slaughter houses. 30 control subjects were also tested. A total of 66 samples (22%) were positive, most of them with low titers. Percentage of positive reactions were higher for persons working in rice fields, followed by those working in slaughter houses and animal farms. The 21-40 year age group was most affected in all working sites. Serovars found most commonly were ichterohemorrhagic in rice field workers, hardjo and ballum in slaughter houses and pomona and hardjo in animal farms.
265名从事钩端螺旋体病高风险工作的受试者接受了钩端螺旋体显微镜凝集试验。其中122人在动物养殖场工作，71人在稻田工作，72人在屠宰场工作。还对30名对照受试者进行了检测。总共66个样本（22%）呈阳性，其中大多数滴度较低。稻田工作者的阳性反应百分比更高，其次是屠宰场和动物养殖场的工作者。在所有工作场所中，21至40岁年龄组受影响最大。稻田工作者中最常见的血清型是出血性黄疸型，屠宰场中是哈焦型和拜伦型，动物养殖场中是波摩那型和哈焦型。
