Alcoholic hepatitis( AH) is a severe alcohol-associated liver disease with a mortality rate as high as 40%. A recent study reveals that the exotoxin( cytolysin)-secreting gut bacterium Enterococcus faecalis is a critical factor for AH,which can be eliminated by bacteriophages,and therefore,the use of bacteriophages for the treatment of AH provide a new treatment option for AH. This article introduces this pioneering study and the knowledge of bacteriophages and cytolysin,so as to provide a theoretical basis for the clinical research on AH.
