Abstract

Listeriosis is an important foodborne zoonotic disease affecting humans and animals in Ethiopia. This review aims to synthesize the epidemiology, prevalence, distribution, and antimicrobial resistance of Listeria species in the country. The literature reveals a widespread occurrence of Listeria infection in humans, animals, and food products, with an average prevalence of 21.6% for Listeria species and 6.9% for . Three sequence types (STs) of (2, 145, and 18) and twelve STs of (1489, 1619, 603, 537, 1010, 3186, 492, 3007, 1087, 474, 1008, and 637) were reported from milk and dairy products. Contamination rates ranged from 4.1% to 42.9% across livestock, dairy, slaughterhouses, and processing facilities, indicating faults in production practices. Sporadic human listeriosis outbreaks have occurred since 1967, causing meningitis, perinatal infections, and deaths, with recent studies showing isolation in up to 10.4% of febrile patients, confirming foodborne transmission. Non-pathogenic Listeria species were also common on farms and in facilities. Ovine listeriosis poses a threat to Ethiopia's sheep and goat industries, with over 40% seroprevalence in some herds. Comprehensive control measures across the food chain are needed to curb contamination and protect public health. Isolates from various foods show antibiotic resistance to first-line agents but susceptibility to others like gentamicin and cephalosporins. In conclusion, this review synthesizes evidence on Listeria distribution in Ethiopia's food system and disease burden, highlighting the need for improved food safety policies and awareness.

摘要

李斯特菌病是一种重要的食源性人畜共患病,在埃塞俄比亚影响着人类和动物。本综述旨在综合该国李斯特菌属的流行病学、患病率、分布及抗菌药物耐药性情况。文献显示,李斯特菌感染在人类、动物和食品中广泛存在,李斯特菌属的平均患病率为21.6%,[此处原文缺失一种菌的名称及对应患病率数据]为6.9%。从牛奶和乳制品中报告了[此处原文缺失一种菌的名称]的三种序列类型(STs,即2、145和18)以及[此处原文缺失一种菌的名称]的十二种STs(1489、1619、603、537、1010、3186、492、3007、1087、474、1008和637)。在牲畜、乳制品、屠宰场和加工设施中,污染率在4.1%至42.9%之间,表明生产环节存在问题。自1967年以来,已发生散发的人类李斯特菌病暴发,导致脑膜炎、围产期感染和死亡,近期研究显示,在高达10.4%的发热患者中分离出[此处原文缺失一种菌的名称],证实了食源性传播。非致病性李斯特菌属在农场和设施中也很常见。绵羊李斯特菌病对埃塞俄比亚的绵羊和山羊产业构成威胁,部分畜群的血清阳性率超过40%。需要在整个食物链采取综合控制措施,以遏制污染并保护公众健康。从各种食品中分离出的菌株对一线抗菌药物具有耐药性,但对庆大霉素和头孢菌素等其他药物敏感。总之,本综述综合了埃塞俄比亚食品系统中李斯特菌分布及疾病负担的证据,强调了改进食品安全政策和提高认识的必要性。
