Ica operon of staphylococcus epidermidis and biomaterial infection / 国际生物医学工程杂志

ABSTRACT

Staphylococcus epidermidis(SE)is the main opportunistic pathogen in nosocomial infections.It usually enter the body along with biomedical materials and adheres to the surface of biomaterials to form bacterial bi06lm.SE bi06lm bears high organized multi.cell colony structure.Bacterial biofilm iS the key reason for refractoriness of biomaterial originated infection.This paper gives an overview of the research progresses in biomaterial related infection,including SE ica operon,formation of biofilm,biofilm treatment,and SO on.Our review shows that studies of SE biofilm were COnfined to the mutated strain from laboratory and growth pattern of plankton and thus the natural clinical pathogenic procedure of SE can't be fully described.Further study should be carried out on formation of SE biofilm and treatment of infections related to the clinical application of biomaterials.
