The <i>Staphylococcus aureus</i> objective of this study was to determine the prevalence and assess the level of resistance to quinolones of <i>Staphylococcus aureus</i> trains isolated in the Hospital and University Center of Brazzaville (CHU-B). 40 strains of <i>Staphylococcus aureus</i> from various biological products were isolated and identified by bacteriological methods. The study of the resistance of these different strains to antibiotics (Quinolones/Fluoroquinolones) was carried out by the phenotypic method, by antibiogram. A total of 40 <i>Staphylococcus aureus</i> strains were isolated including 13 (32.50%) community strains, 27 (67.5%) clinical strains distributed as follows: neonatal and pediatric service 29.62% and 25.92%, surgery 18.51%, contagious 14.81%, emergencies 7.4% and delivery block 3.7%. 60% of strains were isolated in women and 40% in men. The average age of those infected was 16 years and older. 90% strains were resistant to Nalidixic acid (AN), 72.5% to Ofloxacin (OFL), 67.5% to Ciprofloxacin (CIP), 70% to Norfloxacin (NOR), 62.5% to Levofloxacin (LEV), 47.5% to Moxifloxacin (MXF), and 40% strains were resistant to all antibiotics tested.展开更多
