Antibiotic Resistance Pattern of Common Uropathogens among Adult Inpatients of a Tertiary Teaching Hospital

Introduction: Urinary tract infection is one of the common community and nosocomial problem that we encounter at a daily basis. The mounting problem of emergence of resistant strains of bacteria causing urinary tract infection (UTI) is a great concern. We had tried in this study to outline the local pattern of antibiotic resistance of the commonly found uropathogens.

Materials and Methods: This descriptive study was carried out in the Ad-din Sakina Women’s Medical College Hospital, Jashore, Bangladesh on patients attending inpatient Department from January to December 2020. Presence of more than or equal to 105 colony forming units/ml in urine culture was considered as significant for UTI. Isolated bacteria were tested by disk diffusion method.

Results: Out of 1170 urine sample tested, 372 (31.8%) were found to be culture positive cases. A clear female preponderance (77.15%) was noted in positive culture rate. E. coli was the commonest organism found among all isolates (82.25%) followed by enterococci (4.3%), klebsiella (3.76%), pseudomonas (2.95%), proteus (2.68%), enterobacter (2.15%) and Staphylococcus aureus (1.88%). High resistance was noted in E. coli isolates against nalidixic acid (77%), Cefuroxime (75%), azithromycine (61%), cefotaxime (58%) and ceftazidime (54%). The antibiotic which showed least resistance overall includes imipenem, meropenem, nitrofurantoin and gentamicin.

Conclusions: Antibiotic stewardship in accordance to local resistance and sensitivity pattern of uropathogens is mandatory to prevent the development of multidrug resistant strains.
