(Cp.) is the cause of human foodborne desease. Meat and poultry products are identified as the main source of infection for humans. Cp. can be found in poultry litter, feces, soil, dust, and healthy birds' intestinal contents. Cp. strains are known to secrete over 20 identified toxins and enzymes that could potentially be the principal virulence factors, capable of degrading mucin, affecting enterocytes, and the small intestine epithelium, involved in necrotic enteritis (NE) pathophysiology, also leading to immunological responses, microbiota modification and anatomical changes. Different environmental and dietary factors can determine the colonization of this microorganism. It has been observed that the incidence of Cp-associated to NE in broilers has increased in countries that have stopped using antibiotic growth promoters. Since the banning of such antibiotic growth promoters, several strategies for Cp. control have been proposed, including dietary modifications, probiotics, prebiotics, synbiotics, phytogenics, organic acids, and vaccines. However, there are aspects of the pathology that still need to be clarified to establish better actions to control and prevention. This paper reviews the current knowledge about Cp. as foodborne pathogen, the pathophysiology of NE, and recent findings on potential strategies for its control.
产气荚膜梭菌(Cp.)是人类食源性疾病的病因。肉类和家禽产品被确定为人类的主要感染源。Cp.可存在于家禽垫料、粪便、土壤、灰尘以及健康鸟类的肠道内容物中。已知Cp.菌株会分泌超过20种已确定的毒素和酶,这些可能是主要的毒力因子,能够降解粘蛋白、影响肠上皮细胞和小肠上皮,参与坏死性肠炎(NE)的病理生理过程,还会导致免疫反应、微生物群改变和解剖学变化。不同的环境和饮食因素可决定这种微生物的定植。据观察,在已停止使用抗生素生长促进剂的国家,肉鸡中与NE相关的Cp.发病率有所增加。自从禁止使用此类抗生素生长促进剂以来,已经提出了几种控制Cp.的策略,包括饮食调整、益生菌、益生元、合生元、植物源产品、有机酸和疫苗。然而,仍有一些病理学方面的问题需要阐明,以便制定更好的控制和预防措施。本文综述了关于Cp.作为食源性病原体、NE的病理生理学以及其控制潜在策略的最新研究成果。
