Paratuberculosis is a chronic enteric disease affecting virtually all ruminants, but only anecdotal information is currently available about the occurrence of this disease in water buffaloes (Bubalus bubalis). We carried out a survey study aimed at determining the prevalence of paratuberculosis in 2 provinces in the region of Campania, Italy, where about half of all Italian buffaloes are reared. From May 2017 to December 2018, we collected 201,175 individual serum samples from 995 buffalo herds. The sera were collected from animals over 24 mo old and were tested using a commercial ELISA test. The herd-level apparent prevalence result was 54.7%, and the animal-level apparent prevalence was 1.8%. The herd-level true prevalence was estimated using a Bayesian approach, demonstrating a high herd-level prevalence of paratuberculosis in water buffaloes from the Campania area. These findings suggest that the urgent adoption of paratuberculosis herd-control programs for water buffaloes in this area would be beneficial.
副结核病是一种影响几乎所有反刍动物的慢性肠道疾病，但目前关于这种疾病在水牛（Bubalus bubalis）中的发生情况仅有一些传闻信息。我们进行了一项调查研究，旨在确定意大利坎帕尼亚地区的 2 个省份副结核病的流行情况，该地区饲养了大约一半的意大利水牛。从 2017 年 5 月到 2018 年 12 月，我们从 995 个水牛群中收集了 201,175 份个体血清样本。这些血清是从 24 个月以上的动物身上采集的，并使用商业 ELISA 检测进行了测试。群体水平的显性流行率结果为 54.7%，个体水平的显性流行率为 1.8%。使用贝叶斯方法估计了群体水平的真实流行率，结果表明坎帕尼亚地区的水牛存在副结核病的高群体水平流行。这些发现表明，该地区迫切需要为水牛实施副结核病群体控制计划。
