Adhesion, biofilm and genotypic characteristics of antimicrobial resistant Escherichia coli isolates

Cergole-Novella, Maria CPignatari, Antonio CCGuth, Beatriz EC

Aggregative adherence to human epithelial cells, most to renal proximal tubular (HK-2) cells, and biofilm formation was identified among antimicrobial resistant Escherichia coli strains mainly isolated from bacteremia. The importance of these virulence properties contributing to host colonization and infection associated with multiresistant E. coli should not be neglected.(AU)
