ABSTRACT: Staphylococcus aureus is a gram-positive pathogenic bacterium responsible for various infections including skin suppurations. Quinolones are sometimes used last in infections. The Staphylococcus aureus objective of this study was to determine the prevalence and assess the level of resistance to quinolones of Staphylococcus aureus trains isolated in the Hospital and University Center of Brazzaville (CHU-B). 40 strains of Staphylococcus aureus 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 Staphylococcus aureus 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.
