畜禽沙门氏菌病防制研究进展

Research Progress on Salmonellosis Prevention and Control in Livestock and Poultry

沙门氏菌为肠杆菌科沙门氏菌属成员,具有约2 600种血清型,其在自然界中十分普遍,是一种条件致病菌,对畜禽健康、人类公共安全、食品安全都有严重的影响。近年来,随着养殖业的迅速发展,沙门氏菌对畜禽养殖业的影响越来越严重。实际生产中的抗生素滥用导致沙门氏菌的耐药状况愈发严重,致病性沙门氏菌可引起猪副伤寒、鸡白痢、禽伤寒、禽副伤寒等畜禽疾病,非致病性沙门氏菌可能造成动物源性食品的污染,加大了防制的难度。作者主要从沙门氏菌临床诊断、实验室诊断及预防和治疗中存在的问题进行了综述,以期为畜禽沙门氏菌病防制措施的改进提供参考依据。

Salmonellais a member of the Salmonellafamily of Enterobacteriaceae and has about2 600 different serotypes.As a widely distributed conditional pathogen,it has a serious impact on animal health,public safety and food safety.Pathogenic Salmonellacan cause paratyphoid fever,pullorosis,avian typhoid and avian paratyphoid,non-pathogenic Salmonella may cause the contamination of animal-derived food.With the rapid development of aquaculture in recent years,the adverse effects of Salmonellato livestock and poultry breeding industry is more and more terrible.Antibiotic resistance of Salmonellaresulting from abuse of antimicrobial agents is becoming more serious,thereby increasing the difficulty of Salmonella control.In this paper,Salmonella clinical diagnosis,laboratory diagnosis,the problems of prevention and treatment were reviewed in order to provide a reference for the improvement of salmonellosis prevention and control of livestock and poultry.
