Objectives: Pseudomonas species cause urinary tract infection (UTI). This study was conducted to isolate Pseudomonas species causing significant bacteriuria and to analyze its antibiogram at a tertiary care hospital. Methods: About 107 urine samples received in the laboratory from August 2015 to July 2016 having significant bacteriuria with Pseudomonas species were tested for antimicrobial activity. Samples were from both inpatients and patients attending as outpatients to a tertiary care hospital with different age groups and gender. Midstream urine samples were inoculated using a standard calibrated loop into blood agar and MacConkey agar following semi quantitative technique using Kass concept. MALD (Biomerio, ElToile, France) was used for speciation, and Vitex automated system (Biomerio, ElToile, France) was used for antibacterial sensitivity testing. Results: About 107 urine samples contained Pseudomonas species by MALDI obtained from 69 male (64.48%) and 38 (35.51%) female patients. Inpatients were 90 (84.11%) and 17 (15.88%) outpatient department (OPD) patients. Isolation of Pseudomonas aeruginosa was from 90 samples (84.11%) and Pseudomonas putida in 17 (15.88%). Significant bacteriuria was more in the age group of ˃60 years in both genders. Susceptibility to gentamicin was 52 (48.59%), ceftazidime 56 (52.33%), and imipenem was 58 (54.20%). Organism was multidrug resistant in 49 (45.79%) samples. Conclusion: P. aeruginosa remains the most common uropathogen among Pseudomonas species. Drug of choice for inpatients suffering from UTI by Pseudomonas species can be gentamicin and for patients attending OPD can be ceftazidime. Imipenem can be the reserve drug. Periodic antibiotic review is required for proper treatment of UTI.
