【摘要】：畜禽坏死性肠炎主要是由产气荚膜梭菌引起的一种急性消化道传染病,具有较高的发病率和死亡率。该病不仅损害畜禽健康,影响动物福利,而且对养殖业发展及人类健康造成了严重威胁。抗菌药的出现对该病起到了积极限制的作用,然而随着抗菌药的不合理使用,耐药菌株不断增加,坏死性肠炎的发病率呈现升高的趋势,防制坏死性肠炎面临严峻挑战。作者从坏死性肠炎的特征入手,综述了坏死性肠炎的病原学、理化特性、流行病学、临床症状等,与此同时对坏死性肠炎的防制措施及目前常用药物进行了总结,客观分析了防制坏死性肠炎的趋势与发展方向,旨在健全对该病的认识,为坏死性肠炎的防制研究提供参考。
[Abstract]:Necrotizing enteritis of livestock and poultry is an acute gastrointestinal infection caused by Clostridium perfringens with high morbidity and mortality. The disease not only harms the health of livestock and poultry and affects the welfare of animals, but also poses a serious threat to the development of aquaculture and human health. The emergence of antimicrobial agents has played a positive role in limiting the disease. However, with the irrational use of antimicrobial agents, drug-resistant strains continue to increase, the incidence of necrotizing enteritis is increasing, and the prevention of necrotizing enteritis is facing severe challenges. Based on the characteristics of necrotizing enteritis, the authors summarized the etiology, physical and chemical characteristics, epidemiology, clinical symptoms of necrotizing enteritis. At the same time, the prevention and control measures of necrotizing enteritis and the current commonly used drugs were summarized. The trend and development direction of prevention and control of necrotizing enteritis were analyzed objectively in order to improve the understanding of the disease and provide a reference for the prevention and control of necrotizing enteritis.
