With excessive utilization of antibiotics in recent years,bacterial drug resistance problem is serious increasingly,and it is more and more difficult to develop anti-infective drug,while it does not have these problems to use phage controlling disease.Phage is a kind of prokaryotic virus,widely exists in the nature and includes bacteriophage,cyanophage and actinophage.Due to its potential of replacing antibiotics to treat disease,phage receives more and more attention.In this paper,based on development status of phage research at home and abroad,discovery process,naming method and classification basis of phage are introduced comprehensively,and advantages and limitations of phage applying in prevention and control of bacterial diseases are analyzed.We introduce application status of phage in human medicine,prevention and control of diseases for terrestrial animals and aquaculture,and the effects of phage in sewage treatment,prevention and control of microbial contamination of food and detection technology,and point out the shortages of phage in the above application.Meanwhile,we also discuss application prospects of phage in disease prevention and control,environmental protection and food safety.
