Campylobacter spp. are widely distributed microorganisms, many of which are commensals of gastrointestinal tract in multiple animal species, including poultry. Most commonly detected are C. jejuni and C. coli. Although infections are usually asymptomatic in poultry, poultry meat and products represent main sources of infection with these bacteria to humans. According to recent EFSA report, campylobacteriosis is the most commonly reported zoonotic disease. In 2018, EFSA Panel on Biological Hazards indicated that use of feed and water additives is the second most likely strategy that can be successful in minimizing Campylobacter spp. colonization rate in broiler chickens. One of those feed and water additives are probiotics. From numerous research papers it can be concluded that probiotics exhibit plenty of mechanisms of anti-Campylobacter activity, which were evaluated under in vitro conditions. These results, to some extent, can explain the efficacy of probiotics in in vivo studies, although different outcome can be observed under these two laboratory conditions. Probiotics are capable of reducing Campylobacter spp. population count in poultry gastrointestinal tract and they can reduce carcass contamination. Potential modes of anti-Campylobacter activity of probiotics, results of in vivo studies and studies performed at a farm level are widely discussed in the paper.

使用益生菌减少弯曲杆菌属。家禽中的患病率

弯曲杆菌属 是广泛分布的微生物，其中许多是包括家禽在内的多种动物物种胃肠道的共生菌。最常检测到的是空肠弯曲菌和大肠杆菌。尽管家禽感染通常无症状，但家禽肉和产品是人类感染这些细菌的主要来源。根据欧洲食品安全局最近的报告，弯曲杆菌病是最常见的人畜共患疾病。2018 年，欧洲食品安全局生物危害小组表示，使用饲料和水添加剂是第二个最有可能成功减少弯曲杆菌属的策略。肉鸡的定植率。这些饲料和水添加剂之一是益生菌。从大量研究论文中可以得出结论，益生菌表现出多种抗弯曲杆菌活性机制，并在体外条件下进行了评估。这些结果在某种程度上可以解释益生菌在体内研究中的功效，尽管在这两种实验室条件下可以观察到不同的结果。益生菌能够减少弯曲杆菌属。家禽胃肠道中的种群数量，可以减少屠体污染。本文广泛讨论了益生菌抗弯曲杆菌活性的潜在模式、体内研究结果以及在农场水平进行的研究。
