Prevalence and Antimicrobial sensitivity of Coagulase negative Staphylococcus Isolated from patients of Urinary tract infection
Keywords:

Introduction: Urinary tract infection (UTI) is the second most common infectious presentation in community medical practice. E.coli is the most frequent infecting organism in acute infection.Coagulase Negative Staphylococci are a common cause of urinary tract infection in some reports. Staphylococci saprophyticus tends to cause infection in young women of a sexually active age.
Aims & Objective: To isolate Coagulase negative Staphylococcus (CoNS) causing urinary tract infections & its Antimicrobial Sensitivity.
Material and Methods: Clean-Catch midstream urine of the patients was collected. Urine specimens were cultured for isolation of the microbial agents of UTI. All the isolates were identified as Coagulase negative Staphylococcus by Gram staining, Catalase test, Coagulase test & then followed by antimicrobial sensitivity (as per CLSI guidelines).
Results & Conclusion: A total 255 urine samples of UTI suspected patients were screened 101 (39.60%) patients were positive for growth of which 80 (79.20%) were females and 21 (20.79%) Male.The isolation percentages of Gram positive uropathogens were found as 38 (37.62%) in which Coagulase negative Staphylococcus 16 (42.10%). Most Coagulase negative Staphylococcus occurring in UTIs are found to show maximum Antimicrobial sensitivity against Vancomycin and minimum sensitivity against Co-trimoxazole.
