- Abstract
To evaluate the resistance to fluoroquinolones in clinical isolates of Gram-positive cocci records of processed culture al the Bacteriological Reference Center of the Autonomous Service University Hospital of Maracaibo during the period January 2011-December 2015, were reviewed. The data was analyzed using WHONETTM software (version 5.6) and IBM® SPSS® Statistics for Windows (version 25). A frequency of 29.70% was found for Gram-positive cocci (9,292 strains), with 76.18% of isolates corresponding to the genus Staphylococcus (7,072); 15.30% to Enterococcus (1422) and 8.59% to Streptococcus (798). For Staphylococcus, resistance was higher in methicillin-resistant strains. The highest resistance rates were detected in enterococci, especially vancomycin-resistant Enterococcus faecium. No resistance to fluoroquinolones was detected in vancomycin-resistant Enterococcus faecalis strains. Streptococci, including Streptococcus pneumoniae, were mostly sensitive to fluoroquinolones. Most strains of staphylococci and enterococci; presented cross resistance to all tested fluoroquinolones. The distribution of resistance to fluoroquinolones per year of study in each bacterial genus was different. Resistance to fluoroquinolones shows an increasing trend in the three genera of Grampositive cocci evaluated.
