Tuberculosis (TB) is considered one of the most widespread and devastating zoonotic diseases in low-income countries, with a cosmopolitan distribution. The aim of this 10-year retrospective survey (from 2011 to 2020) was to determine the frequency of bovine, ovine, and goat tuberculosis in different local slaughterhouses across Constantine Province, Algeria. The control of livestock carcasses was systematically performed by veterinarian inspectors, after each stage of the slaughter process. The routine abattoir inspection included the detection of visible abnormalities on different organs and lymph nodes. The overall prevalence of tuberculosis recorded in slaughtered animals was 0.83%, with the following distribution among species: 2.73% in cattle, 0.001% in sheep, and 0.0% in goats. During the study period, there was a strong correlation ( = 0.82) ( < 0.01) between tuberculosis occurrence and the number of slaughtered cattle. Fluctuations in monthly TB prevalence ranged from 2% to 24.8% between 2018 and 2020, although there were no statistically significant correlations between infection and the age or gender of the animals, except for the year 2020 when a significantly higher ( = 0.017) percentage of TB cases were recorded in female cattle compared to male cattle. The average monthly weight of the confiscated livers and lungs ranged significantly ( ≤ 0.05) from 150 kg to 350 kg. The study results provide baseline data regarding livestock tuberculosis monitoring in the area of Constantine, Algeria, indicating that the disease incidence is not highly alarming, yet remains a serious public and animal health issue in the screened region.
结核病被认为是低收入国家中分布最广泛、危害最大的人畜共患病之一,呈世界性分布。这项为期10年的回顾性调查(2011年至2020年)旨在确定阿尔及利亚君士坦丁省不同当地屠宰场中牛、羊和山羊结核病的发病频率。兽医检查员在屠宰过程的每个阶段后,对牲畜尸体进行系统检查。屠宰场的常规检查包括检测不同器官和淋巴结上的可见异常。屠宰动物中记录的结核病总体患病率为0.83%,各物种分布如下:牛为2.73%,绵羊为0.001%,山羊为0.0%。在研究期间,结核病发病与屠宰牛的数量之间存在强相关性(=0.82)(<0.01)。2018年至2020年期间,每月结核病患病率波动范围为2%至24.8%,尽管感染与动物年龄或性别之间没有统计学上的显著相关性,但在2020年,雌性牛的结核病病例记录百分比显著高于雄性牛(=0.017)。没收的肝脏和肺的平均每月重量在150千克至350千克之间存在显著差异(≤0.05)。研究结果提供了阿尔及利亚君士坦丁地区牲畜结核病监测的基线数据,表明该病发病率虽未达到高度警戒水平,但在筛查地区仍是一个严重的公共卫生和动物健康问题。
