A study on urinary staphylococci as uropathogens at a tertiary care hospital

Background: Staphylococci as a cause of UTI is not uncommon. But studies related to their association with UTI and their resistance patterns are limited.Therefore this study was undertaken to know the rate of isolation of urinary staphylococci with special reference to methicillin resistant strains. Material & Methods: Urine samples collected from clinically suspected UTI cases were processed and those samples which yielded staphylococci were included in the study. Their antibiogram was determined by Kirby-Bauer disc diffusion method . Results: Of the 3170 urine samples processed 1426 were culture positive for various organisms. A total of 273 urinary staphylococci were obtained. 64 of them were Staphylococcus aureus and 209 were Coagulase Negative Staphylococci (CONS), constituting 4.5% and 14.7% of the total isolates.17.2% of those urinary staphylococci were methicillin resistant . Conclusion: This study shows the rate of isolation of urinary staphylococci and their tendency towards resistance.
