Abstract

Caseous lymphadenitis, also called abscess disease, is an infectious, cosmopolitan disease. The causative agent is a Gram-positive bacillus, Corynebacterium pseudotuberculosis that is resistant to antibiotic treatment. Humans become infected with this bacillus, but the disease is considered a neglected zoonosis. The objective of this study was to estimate the prevalence and to identify Corynebacterium pseudotuberculosis in sheep slaughtered in central Algeria. For this purpose, 897 animals were examined and samples (pus) were taken from 12 sheep with abscesses to perform bacteriological study. Sex, age, and location of the abscess were noted. The results obtained showed an overall prevalence of 1.33%. The highest rate (50%) was observed in animals aged between 8 months and 1 year. Males were more affected by abscesses (66.7%) than females (33.3%). As for localisation, 41% of abscesses were found in the pulmonary lymph nodes and 25% in the submandibular region. Infection by Corynebacterium was estimated at a rate of 25%, lower than that obtained for Staphylococcus (41.7%). Regarding the zoonotic nature of the disease, the bacteria’s ability to survive in the external environment, and the high risk of contamination, management measures should be implemented for better disease control and prevention.

阿尔及利亚中部屠宰羊中假结核棒状杆菌的流行和鉴定

干酪性淋巴结炎，又称脓肿病，是一种世界性传染病。病原体是一种革兰氏阳性杆菌，对抗生素治疗具有耐药性的假结核棒状杆菌。人类感染这种芽孢杆菌，但这种疾病被认为是一种被忽视的人畜共患病。本研究的目的是估计阿尔及利亚中部屠宰的绵羊中假结核棒状杆菌的流行率并鉴定。为此，对897只动物进行了检查，并从12只有脓肿的羊身上提取了样本(脓液)进行细菌学研究。记录脓肿的性别、年龄和位置。结果显示，总患病率为1.33%。在8个月~ 1岁的动物中，发病率最高(50%)。男性(66.7%)高于女性(33.3%)。至于脓肿的定位，41%的脓肿位于肺淋巴结，25%位于下颌下区。杆状杆菌的感染率估计为25%，低于葡萄球菌的感染率(41.7%)。针对该病的人畜共患性、细菌在外界环境中的生存能力和污染的高风险，应实施管理措施，以更好地控制和预防疾病。
