Antimicrobial susceptibility pattern of human pathogenic bacteria isolated from patients with urinary tract infection

Aim and Urinary tract infections (UTIs) are widespread health concerns which differ according to geography and regions. Bacterial Urinary tract infections associated with an enlarged antimicrobial resistant species are found in all age groups.The aim of this study was to ascertain the antimicrobial resistance pattern of strains isolated from patients with Urinary Tract Infection (UTI) and the emergence of multidrug resistant bacterial strains. Midstream urine samples were collected from 2235 patients and analyzed for isolation and identification of Multidrug Resistant (MDR) strains. The MDR strains were recognized by the Kirby Bauer method according to National Committee of Clinical Laboratory Standards. Female patients constituted 308 (62%) in the study. This result indicates that E.coli is the predominant pathogen causing UTI, followed by Klebsiella, Streptococcus viridans, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, Proteus and Pseudomonas. Bacterial isolates from patients with UTI showed high levels of single and multiple antimicrobial resistances against commonly prescribed drugs. The present study confirms that bacterial resistance would be a serious problem in the country. Therefore, antimicrobial surveillance and in vitro susceptibility testing with strict adherence to antibiotic policy may facilitate to control the spreading of drug resistant microbes.
