摘要
产气荚膜梭菌是一种引起人类和动物肠道感染和组织坏死的重要食源性病原体,致死因子是其产生的多种外毒素。合理使用抗菌药物及健康养殖需求的增加使疫苗预防更为重要。然而,传统的产气荚膜梭菌外毒素疫苗可能存在效果不稳定及残留毒素和甲醛等问题,引发了人们对这些疫苗安全性的担忧。该文系统介绍了产气荚膜梭菌的传统类毒素疫苗、基因工程重组疫苗及基于反向疫苗学和免疫信息学设计的表位肽疫苗最新研究进展,为研发制备有效、安全的新型产气荚膜梭菌毒素疫苗提供新思路。
Clostridium perfringens is an important foodborne pathogen that causes intestinal infections and tissue necrosis in both human and animals.A variety of exotoxins it produces are lethal.The increasing demand for ratio-nal use of antimicrobial agents and healthy farming make the implementation of vaccination critically important.However,traditional Clostridium perfringens exotoxin vaccines may have problems such as inconsistent efficacy,residual toxins and formaldehyde,raising concerns about the safety of these vaccines.This article systematically introduces the latest research progress in traditional toxoid vaccine,genetically engineered recombinant vaccines,and epitope peptide vaccines designed based on reverse vaccinology and immunoinformatics for Clostridium perfringens,providing new ideas for the development and preparation of effective and safe novel Clostridium perfringens toxin vaccines.
