ABSTRACT
Klebsiella pneumoniae is mainly responsible for nosocomial and urinary tract infections (UTIs) in pediatric and adult population. The ESBL producing K. pneumoniae present an alarming situation for clinicians by limiting the treatment options. We aimed to determine the antibiotic resistance pattern and characterization of ESBL producing K. pneumoniae isolated from children of different age groups. K. pneumoniae isolated from blood and urine samples were identified through API® 20E kit. Antibiogram was determined by disc diffusion method and isolates were screened for ESBL production using double-disc synergy test (DDST). Molecular detection for the presence of bla-SHV and bla-TEM was carried out by polymerase chain reaction (PCR). Of 392 blood and urine samples, 120 were found positive for microbial growth. Antibiotic susceptibility testing of K. pneumoniae isolates illustrated high resistance to ceftazidime (95.6%). Phenotypically,52.17% of K. pneumoniae isolates were found to be ESBL producers as observed by double disc synergy test while the tested ESBL genes were detected in 56.52% of isolates. The studyrevealed multidrug resistance phenotypes among K. pneumoniae isolates with higher prevalence of ESBL producing Klebsiella pneumoniae among the children with urinary tract infections. Based on our findings, it is recommended that the ESBL production should be routinely monitored especially among the K. pneumoniae strains for the effective management and control of such MDR pathogens.
