Research Progress on Salmonellosis Prevention and Control in Livestock and Poultry

Salmonella is a member of the Salmonella family of Enterobacteriaceae and has about 2 600 different serotypes. As a widely distributed conditional pathogen,it has a serious impact on animal health, public safety and food safety.Pathogenic Salmonella can 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 Salmonella to livestock and poultry breeding industry is more and more terrible.Antibiotic resistance of Salmonella resulting 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.
