J. Silverman et al., EPIDEMIOLOGIC EVALUATION OF ANTIMICROBIAL RESISTANCE IN COMMUNITY-ACQUIRED ENTEROCOCCI, Journal of clinical microbiology, 36(3), 1998, pp. 830-832
Fecal samples from 200 consecutive patients admitted to a community ho
spital yielded 107 enterococci. High-level gentamicin resistance occur
red in 10 (14%) of the Enterococcus faecalis isolates. Ampicillin resi
stance occurred in two (3%) of the E. faecalis isolates and six (23%)
of the Enterococcus faecium isolates. There were no vancomycin-resista
nt enterococci. Risk factors for enterococci with high-level aminoglyc
oside (gentamicin) or ampicillin resistance included prior hospitaliza
tion and previous antibiotic use.
