Antibiotic Susceptibility Changes of Staphylococcus Aureus a Retrospective Study

Abstract

Antibiotherapy resistance is an emerging health care issue due to the extended usage of antibiotics. The aim of the study was to determine the changes in antibiotherapy resistance of Staphylococcus aureus over a 5 years period between 2003 to 2007. Patients and method: retrospective study over a 5 years period that analyzed the resistance trends of Staphylococcus aureus in the cultures of newborns, that were taken at the Newborn Department of the Children’ Hospital of the Transilvania University. Results: 116 strains were studied, strains from skin lesions, umbilical secretion, blood culture, eye secretion, nasal and pharyngeal swab. From these 94 were resistant to penicillin, 74.1% sensible to meticillin, 9.48% resistant to gentamicin, 72% sensible to ciprofloxacin and 72% sensible to clindamicin. Conclusions: there was in our study a slight predominance of boys. We observe a constant trend towards metcillin resistance. Most of the meticillin resistant strains were isolated from skin lesions. Still active antibiotics are clindamicin, gentamicin and rifampicin.
