This study investigated the species prevalence and antibacterial resistance among enterococci isolated in Kuwait hospitals. They consisted of 415 isolates of Enterococcus faecalis (85·3 %), Enterococcus faecium (7·7 %), Enterococcus casseliflavus (4·0 %), Enterococcus avium (1·2 %), Enterococcus durans (1·0 %), Enterococcus gallinarium (0·5 %) and Enterococcus bovis (0·2 %) isolated from urine (36·6 %), blood (10·4 %), wound swabs (11·0 %), stool samples (12·0 %), high vaginal swabs (9·0 %), endocervical swabs (3·0 %) and miscellaneous sources (18·0 %). All of them were susceptible to linezolid. Fifty-two (12·5 %) isolates were ampicillin resistant but none of them produced â-lactamase. They were resistant to erythromycin (63·3 %), tetracycline (60·5 %), ciprofloxacin (40·0 %), chloramphenicol (28·0 %), vancomycin (2·6 %), and teicoplanin (2·6 %). Fourteen, 19 and 20 % of them expressed high-level resistance to gentamicin, kanamycin and streptomycin, respectively. All of the vancomycin-resistant strains carried the vanA phenotype and genotype. There was no evidence of clonal spread of the vancomycin-resistant isolates.
