A STUDY ON IN VITRO ACTIVITY OF FOSFOMYCIN AGAINST ENTEROBACTERIACAE UROPATHOGEN ALONG WITH MICROBIOLOGICAL PROFILE AND ANTIBIOGRAM OF UROPATHOGENS

Background:Urinary tract infection (UTI) is one of the most common infection throughout the world that may affect both the lower and the upper urinary tracts. Aims & Objective:The present study was done to determine various organisms causing Urinary tract infections and to analyse antimicrobial sensitivity patterns of those isolates. Materials and Methods:This prospective study was conducted from April 2020 to March 2021at SIMS& RH, Tumkur. All urine samples were received in Microbiology laboratory for routine microbiology investigations were inoculated on Blood agar and MacConkey agar culture media using calibrated wire loop . Urinary isolates with significant bacteriuria were further processed by conventional biochemical tests and antimicrobial susceptibility testing was done as per standard methods. Results: A total of 697 urine samples were processed in that 324 (46.48%) samples were shown as significant growth of bacteria. Most of the cases seen in (67.28%) female and under age group of 21-30(22.22%).The predominantly Gram-negative bacteria (85.18%) were isolated followed by Gram positive bacteria(10.49%) and Candida spp(4.32%). The Gram negative bacteria showed high sensitivity to Ampicillin sulbactum (88.27%) followed by Amikacin (87.24%). All Gram-positive bacteria isolates is showed sensitivity to Vancomycin (100%).We found that 235( 92.88%) Enterobacteriaceace isolates were is susceptible for Fosfomycin. Conclusion:. Antibiotic resistance has become a major clinical problem worldwide and has increased over the years.Hence antibiotic susceptibility testing should be done to diagnose and treat the drug resistant UTI cases. Fosfomycin may be given empirically in patients with uncomplicated urinary tract infection due to Enterobacteriaceace.
