Molecular Charactrization of Enterococcus faecalis

Enterococcus faecalis strains are becoming increasingly important agents of human disease, largely because of their resistance to antimicrobial agents. Because of their resistance to penicillins and cephalosporins of several activity ranges, the acquisition of high-level resistance to aminoglycosides, and now the emergence of vancomycin resistance, these bacteria are often involved in serious infections among patients receiving broad-spectrum antimicrobial chemotherapy.In Iraq, little information regarding vancomycin resistance and virulence factors presented in E. faecalis strains. Therefore, there is an increasing request to investigate the role of these strains in hospital infections.This bookprovides a new dataon the prevalence of E. faecalis in patients with significant bacteriuria, the antimicrobial resistance patterns and the presence of virulence genes in the isolated species.
