Enterococci are intrinsically resistant to some antibiotics such as cephalosporins, quinolones, aminoglycosides, clindamycin and erythromycin where the resistance genes are located on the chromosome, or they possess acquired resistance to several antimicrobial agents such as aminoglycosides, [beta]-lactams and glycopeptides which are located on plasmids or transposons and to be able to spread these resistance genes to other species (Mannu et al.
