Bacterial contamination and biofilm formation on abiotic surfaces and strategies to overcome their persistence

Abiotic surfaces are vulnerable to bacterial adhesion and to biofilm formation. therefore,it is necessary to understand the parameters that influence bacterial adhesion to find out solutions against cell adhesion and biofilm formation. the ability of pathogenic bacteria to adhere and to form biofilms on abiotic surfaces represents a major health safety problem. bacteria embedded in biofilms are more resistant to sanitizing agents than those growing under planktonic state. in fact,surface contamination by these pathogens is enhanced by favorable environmental conditions encountered in food and health sectors. thus,the understanding of bacterial adhesion and biofilm formation on abiotic surfaces is of interest to setup efficient anti-biofilm strategies. in this context,this review highlights the main factors controlling the bacterial adhesion and biofilm formation on abiotic surfaces. it also describes the current and emergent strategies used to eradicate and prevent the biofilm formation on the most frequently used abiotic surface. © 2017,university of mohammed premier oujda morocco.
