Brazilian family farming comprises production units that represent approximately 86.40% of agricultural establishments, playing a significant national role in socio-environmental and economic sectors. The state of São Paulo is known for its rural and urban development, including agricultural settlements such as Pontal do Paranapanema. This sector requires attention due to the emergence of infectious diseases, such as leptospirosis, a widespread zoonotic disease that causes losses in agricultural productivity. This study aimed to analyze the prevalence of leptospirosis in dairy cattle within the settlements of Presidente Epitácio and Mirante do Paranapanema. All animals underwent serological testing. The overall prevalence of spp. was 58.93%. Additionally, the prevalence of antibodies against spp. was 59.20% in multiparous cows and 58.60% in primiparous cows. A correlation was also observed between animals with retained placenta and seropositive animals for spp. antibodies. Based on this study, we highlight that the high prevalence of leptospirosis underscores the presence of this pathology in settlements within the Pontal do Paranapanema region. Consequently, there is a need to develop public policy programs, alongside sanitary and control measures, to mitigate the impact on dairy farming in the region.
巴西家庭农业包括一些生产单位，这些单位约占农业企业的86.40%，在社会环境和经济领域发挥着重要的国家作用。圣保罗州以其农村和城市发展而闻名，包括庞塔尔-杜帕拉纳帕内马等农业定居点。由于传染病的出现，该部门需要引起关注，例如钩端螺旋体病，这是一种广泛传播的人畜共患病，会导致农业生产力损失。本研究旨在分析埃皮塔西奥总统镇和帕拉纳帕内马美景镇定居点内奶牛的钩端螺旋体病患病率。所有动物都接受了血清学检测。 spp.的总体患病率为58.93%。此外，经产母牛中抗 spp.抗体的患病率为59.20%，初产母牛中为58.60%。在胎盘滞留的动物和 spp.抗体血清阳性的动物之间也观察到了相关性。基于这项研究，我们强调钩端螺旋体病的高患病率凸显了这种病理状况在庞塔尔-杜帕拉纳帕内马地区定居点的存在。因此，有必要制定公共政策方案，同时采取卫生和控制措施，以减轻对该地区奶牛养殖的影响。
