Descripción : | Resistance in Gram-positive pathogens is a worldwide problem. The decrease of activity of available antibiotics has created a need for new antimicrobial agents. Linezolid is a member of the new class of antimicrobials, the oxazolidinones. Linezolid is active in vitro against staphylococci, streptococci, and Enterococci, including resistant strains such as methicillin-resistant S. aureus, penicillin-resistant Streptococcus pneumoniae, and vancomycinresistant Enterococci. Objective. To determine the in vitro activity of linezolid and other new antimicrobial active against gram-positive cocci. Material and methods. Two hundred and ninety six Grampositive cocci isolated from 4 different hospital in México in 2000 were analyzed. The susceptibility tests included a disk diffusion and the E test. Results. All S. aureus (Oxa-S), S. aureus (Oxa-R), Staphylococcus sp (Oxa-s) and Staphylococcus sp (Oxa-R) were susceptible to linezolid, quinupristin-dalfopristinn and vancomycin. Some Staphylococcus sp (Oxa-R) were resistant to teicoplanin (15%) and to clindamycin (54%). No vancomycin-resistant Enterococci were found. E. faecalis was frequently resistant to quinupristin-dalfopristin (89%). 50% of E. faecium were resistant to ampicillin. Resistance to penicillin in S. pneumoniae was 45%. Conclusions. Linezolid is a new potential treatment option for resistant gram-positive infections. |
