The aim of this study was to analyze the extended spectrum ß-lactamases (ESBLs) production and antibiotic susceptibility profile of urinary tract infected bacterial pathogens such as Escherichia coli and Klebsiella spp. A total of 143 Gram-negative bacteria were isolated from people suffering from urinary tract infections (UTIs) were included in this study. Among them, Escherichia coli (75%) were the predominantly isolated bacterial pathogen followed by Klebsiella oxytoca (14.6%) and K. pneumoniae (10.4%). Approximately 65% (n=93) of isolates were positive for ESBL production and E.coli was found to be the highest ESBL producer (67.6%) followed by K. oxytoca (57.1%) and K. pneumoniae (53.3%). E. coli showed high level of 86.1% resistance to cefotaxime and cefuroxime and 100% sensitive to imipenem and meropenem, whereas, K. oxytoca showed high level of 90.5% resistance to cefuroxime and 100% sensitive to amikacin, imipenem and meropenem. Similarly, K. pneumoniae showed high level of 73.3% resistance to nitrofurantoin and 93.3% sensitive to imipenem. This study reveals that majority of UTIs caused bacteria are ESBL producing multidrug-resistant bacteria and showing broad spectrum antibiotic resistance profile.
