Leptospirosis is a widespread infection among pigs throughout the world. In most cases in Ukraine, only the microscopic agglutination test (MAT) is used for the diagnosis of leptospirosis in animals. In general, during the period of 2001-2019, 2 381 163 samples of blood sera from swine were tested in our country and 85 338 positive reactions were received, which is 3.58% [binomial confidence intervals (BCI), 3.56-3.61%]. It was established that the serovars - 33.91% (BCI, 33.59-34.23%), - 14.14% (BCI, 13.90-14.37%), - 8.58% (BCI, 8.39-8.77%), and - 7.12% (BCI, 6.95-7.30%) play a leading role in the aetiological structure of swine leptospirosis. A large number of positive reactions to several serovars was observed - 29.78% (BCI, 29.47-30.09%) of the total number of positive cases. In addition, the article presents data according to a retrospective analysis of the eight serovars circulating among pigs in Ukraine. Thus, during the nineteen year period, there was a decrease in the number of positive reactions to , , and and an increase in the number of positive reactions to , , and . Mapping Ukraine's territory for leptospirosis among pigs was carried out. This allows one to identify zones with a risk of leptospirosis infections among swine. The maps show that the highest incidence rates were identified in the eastern and central parts of Ukraine.
钩端螺旋体病是一种在全球猪群中广泛传播的感染病。在乌克兰的大多数情况下，仅使用显微镜凝集试验（MAT）来诊断动物的钩端螺旋体病。总体而言，在2001年至2019年期间，我国共检测了2381163份猪血清样本，其中85338份呈阳性反应，阳性率为3.58%[二项式置信区间（BCI），3.56 - 3.61%]。已确定血清型 （33.91%，BCI，33.59 - 34.23%）、 （14.14%，BCI，13.90 - 14.37%）、 （8.58%，BCI，8.39 - 8.77%）和 （7.12%，BCI，6.95 - 7.30%）在猪钩端螺旋体病的病因结构中起主导作用。观察到大量样本对几种血清型呈阳性反应，占阳性病例总数的29.78%（BCI，29.47 - 30.09%）。此外，本文还呈现了对乌克兰猪群中流行的八种血清型进行回顾性分析的数据。因此，在这十九年期间，对 、 和 的阳性反应数量有所下降，而对 、 和 的阳性反应数量有所增加。开展了乌克兰猪群钩端螺旋体病的地域分布图绘制工作。这有助于识别猪群中存在钩端螺旋体病感染风险的区域。地图显示，乌克兰东部和中部地区的发病率最高。
