Background: Appropriate knowledge about the organism and antibiotic susceptibility are the key factors to be known by the health-care professionals for effective treatment of symptomatic urinary tract infection (SUTI). This forms the basis of our study to document the common microbial agents responsible for SUTI and antibiotic susceptibility pattern of pathogens causing SUTI. Materials and Methods: Urine specimens from the patients attending the outpatient department (OPD) and hospitalized patients were collected as per standard microbiological laboratory procedures. Urine specimens were inoculated on blood and MacConkey medium. Plates were incubated overnight at 37°C and the next day were visualized for any visible growth. The characteristic colony character and colony count was taken into consideration. The organisms were later confirmed using conventional biochemical techniques after doing Gram staining. Results: On culture of 2473 specimens, 1940 (78.44%) were sterile and 533 (21.55%) urine specimens yielded significant bacterial growth. Among the 533 positive culture uropathogens isolated, 191 (35.8%) specimens were of males, whereas 342 (64.2%) specimens were of females. The mean ± standard deviation of the age of the patients was 46.1 ± 13.49. Most of the positive specimens, i.e., 316 (59.3%), were from the patients who were >40 years old. The prevalence of Escherichia coli was highest (52.2%), Enterococcus (17.3%), Pseudomonas (7.3%), and Klebsiella (6.0%). Enterococcus (83.7%), methicillin-resistant Staphylococcus aureus(MRSA) (90%), E. coli(93.2%), and Klebsiella (37.5%) isolates were found to be susceptible to nitrofurantoin, whereas Enterococcus (95.7%) and MRSA (95%) isolates were susceptible to antibiotics such as linezolid. All isolates from Morganella species were susceptible to amikacin and gentamicin. Conclusion: E. coli was the most common uropathogen isolated from the urinary specimens, followed by Enterococcus and Pseudomonas among patients who reported with symptoms of UTI in OPD.
