牛分枝杆菌是一种革兰氏阳性的抗酸细菌，在牛和其他几种家畜和野生动物物种中引起疾病，也是人类发病和死亡的一个主要原因。在意大利，牛结核病（bTB）的发病率多年来一直在逐步减少；然而，该病在意大利南部仍很普遍，西西里岛的流行率最高。已经制定了具体的根除规划，将畜群检测和屠宰场的死后检查作为诊断程序，以获取结核流行病学数据。同时使用这些程序在流行病学监测计划中是必不可少的，尽管在西西里岛有系统地收集了畜群水平的疾病流行率数据并用于流行病学监测，但死后检查的数据很少。因此，本次调查旨在利用来自肉类检验和组织病理学方法的数据，调查西西里岛两个不同三年期间牛中bTB的流行情况。所获得的结果表明，尽管多年来牛中bTB的发病率大大减少，但该疾病仍然在该地区广泛传播，对公共卫生造成严重影响，并对畜牧业产生突出的经济影响。屠宰场的死后检查在传染病（包括结核分枝杆菌）的流行病学监测中起着关键作用。本研究利用来自肉类检验和组织病理学方法的数据，评估了西西里岛两个不同三年期（2010-2012年；2017-2019年）牛中bTB的流行情况。在100196头牛中，5221头（5.21%）被诊断为结核性病变。2010-2012三年期bTB患病率（6.74%,n = 3692）高于2017-2019三年期（3.36%,n = 1529），在整个研究期间，年发病率呈下降趋势，西西里各省感染牛的比例差异较大（p < 0.01）。小于12月龄和小于84月龄的动物感染率较低（p < 0.0001）。皮尔逊卡方分析显示，病变在胸腔的定位更高（p < 0.0001）。收集到的调查结果表明，尽管多年来牛中bTB的发病率大大减少，但该疾病仍然在西西里岛广泛传播，也对公共卫生造成严重影响。
Mycobacterium bovis is a Gram-positive, acid-fast bacterium responsible for disease in cattle and in several other domestic and wild animal species, also representing a prominent cause of morbidity and mortality in humans. In Italy, the incidence of bovine tuberculosis (bTB) in cattle has been progressively reduced throughout the years; however, the disease still remains widespread in Southern Italy, with the highest prevalence rates recorded in Sicily. Specific eradication programs have been established, with herd testing and post-mortem inspection at the slaughterhouse used as diagnostic procedures to obtain epidemiological data on bTB prevalence. The concomitant use of these procedures is essential in epidemiological surveillance programs, and although data on disease prevalence at herd level are systematically collected and used for epidemiological surveillance in Sicily, data from post-mortem inspection are scant. Therefore, the current survey aimed to investigate the prevalence of bTB in cattle in Sicily during two different three-year periods, using data from meat inspections and histopathological methods. Results obtained show that even though bTB occurrence in cattle was well reduced over the years, the disease still remains widespread in this region, posing severe implications for public health and a prominent economic impact on the livestock industry. Post-mortem inspection in slaughterhouses plays a key role in the epidemiological surveillance of infectious diseases, including bTB. This study assessed the prevalence of bTB in cattle in Sicily during two different three-year periods (2010–2012; 2017–2019), using data from meat inspections and histopathological methods. Out of 100,196 cattle, 5221 (5.21%) were diagnosed with tuberculous lesions. Higher prevalence of bTB was recorded during the triennium 2010–2012 (6.74%; n = 3692) compared to the triennium 2017–2019 (3.36%; n = 1529), with a decreasing trend in annual occurrence throughout the study period and a heterogenous proportion of infected cattle among the Sicilian provinces (p < 0.01). Lower rates of infection were recorded in animals aged <12 months and >84 months (p < 0.0001). Pearson’s chi square analysis revealed a higher localization of lesions in the thoracic cavity (p < 0.0001). Gathered findings show that even though bTB occurrence in cattle was greatly reduced over the years, the disease still remains widespread in Sicily, also posing severe implications for public health.
