Leptospirosis was diagnosed in 11 milkers on 3 dairy farms in a Florida county. Serologic test results identified Leptospira interrogans serovar hardjo as the infecting organism in milkers and cows on one farm, and hardjo was isolated from two cows. On the second farm, serovars hardjo and pomona were implicated serologically in the cows and milkers, and pomona was isolated from two milkers. On the third farm, hardjo infection was identified by serologic tests in one milker, and hardjo was isolated from another.This was the first isolation of hardjo from a human being reported in the United States. Leptospiral infection is an occupational hazard for dairy milkers in some areas of the United States. Thus, the authors recommend that preventive measures should be taken. These measures should include boots and other protective clothing and protection from urine spray for the eyes and nose.
在佛罗里达州一个县的3个奶牛场中，11名挤奶工被诊断出感染钩端螺旋体病。血清学检测结果表明，一个农场的挤奶工和奶牛感染的病原体为问号钩端螺旋体哈焦血清型，并且从两头奶牛身上分离出了哈焦血清型。在第二个农场，血清学检测表明奶牛和挤奶工感染了哈焦和波摩那血清型，并且从两名挤奶工身上分离出了波摩那血清型。在第三个农场，一名挤奶工经血清学检测确诊感染哈焦血清型，并且从另一名挤奶工身上分离出了哈焦血清型。这是美国首次报道从人类身上分离出哈焦血清型。在美国一些地区，钩端螺旋体感染是奶牛场挤奶工的职业危害。因此，作者建议应采取预防措施。这些措施应包括穿靴子和其他防护服，以及保护眼睛和鼻子免受尿液喷雾的影响。
