| outbreak of infections in a greek university hospital involving a single clone of high-level aminoglycoside-resistant enterococcus faecalis. | among 145 enterococcus faecalis isolates recovered during a 15-month period (april 1997-june 1998) in ahepa university hospital, thessaloniki, greece, 94 (65%) exhibited high-level resistance to gentamicin or streptomycin and 61 (42%) to both aminoglycosides; 73% of the high-level aminoglycoside-resistant e. faecalis isolates belonged to a single clone carrying the gene aac(6')-ie-aph(2")-ia. these findings differ from those of other regions, where high-level aminoglycoside-resistance genes are ... | 2000 | 11140915 |
| increasing prevalence of high-level gentamicin resistance among enterococci isolated in greece. | high-level gentamicin-resistant enterococci (hlgre) (mic >512 microg/ml) were frequently recovered in the ahepa university hospital, thessaloniki, greece, during a 15-month period (67/158, 42.4%). pcr testing showed that high-level gentamicin resistance was attributable to the presence of the aac(6')-aph(2") gene, while the recently described genes aph (2")-ic and aph(2")-id were not detected. high-level gentamicin resistance could be transferred with varying frequency from 41 of 57 enterococcus ... | 2001 | 11173808 |
