is the causative agent of caseous lymphadenitis, a bacterial infection that can affect livestock. This infection can cause low growth rates and milk yields and reproductive failure, along with the infection of humans, especially those in close contact with the animals. The aim of this study was to evaluate the local CLA prevalence, highlighting the parameters for the potential predisposition to infection in goats, and to implement a monitoring program based on the newly acquired scientific evidence. Of a total of 2365 goat farms in South Tyrol, 384 farms were selected for the present study. A statistically significant number of animals were subjected to serologic analysis for the detection of antibodies. A total of 2948 goats belonging to the selected farms were tested for CLA, 713 of which showed a positive result. The data analysis led to an estimated CLA seroprevalence of 21.85%. The results achieved can enable the evaluation and possible implementation of a voluntary program that permits us to test a larger number of animals using serological techniques. This program would be of great importance, especially for those farms dedicated to the production of milk and dairy products, as some manufacturing practices may increase the risk of transmission of zoonotic pathogens such as to humans.
是干酪性淋巴结炎的病原体，这是一种可影响家畜的细菌感染。这种感染会导致生长率和产奶量降低以及繁殖失败，还会感染人类，尤其是那些与动物密切接触的人。本研究的目的是评估当地干酪性淋巴结炎的患病率，突出山羊潜在易感性的参数，并根据新获得的科学证据实施监测计划。在南蒂罗尔的总共2365个山羊养殖场中，选择了384个养殖场进行本研究。对数量具有统计学意义的动物进行血清学分析以检测抗体。对所选养殖场的总共2948只山羊进行了干酪性淋巴结炎检测，其中713只呈阳性结果。数据分析得出干酪性淋巴结炎血清阳性率估计为21.85%。所取得的结果能够评估并可能实施一项自愿计划，该计划使我们能够使用血清学技术检测更多数量的动物。该计划将非常重要，特别是对于那些专门生产牛奶和乳制品的养殖场，因为一些生产操作可能会增加人畜共患病原体如向人类传播的风险。
