Abstract

Background: The rise of Enterobacteriaceae strains that produce an extended spectrum b-lactamase (ESBL) has become a global concern for epidemiological surveillance and the prevention of nosocomial acquired infections in the modern era. The choice of appropriate antibiotics to be employed in the treatment of infections brought on by ESBL-producing bacteria relies greatly on the detection and identification of these ESBLs in the laboratory. Limitations in ESBL detection have aided in the unbridled emergence of bacterial resistance and constitute a major health concern.
Isolation and identification of ESBL among Enterobacteriaceae by phenotypic methodswith their Antibiogram.
Materials and Methods: Phenotypic techniques were used to identify ESBL-producing Enterobacteriaceae (ESBLs-E) isolates from diverse clinical samples. Kirby Baur disc diffusion technique was performed to determine antimicrobial's susceptibility.
Results: Among 212 Enterobacteriaceae isolates 124(58.3%) were positive for ESBL production. E.coli(74.5%) & K.pneumoniae (52.2%) two main isolates that produce ESBLs. Maximum ESBL producing Enterobacteriaceae isolates were obtained from blood samples 82% (41/50) followed by urine 59 % (62/105). Meropenem (96.7%), Amikacin (82.1%), and Cefoxitin were most susceptible antibiotics for ESBL-producing isolates while high resistance was observed in ceftazidime (62%), followed by Ciprofloxacin (60%).
Conclusion: The majority of ESBLs-E was mostly found in urine and blood samples.It was observed that E.coli produced the most ESBLs. There was a high prevalence of ESBLs-E in tertiary care hospital of central India. Therefore, strong infection control strategies must be implemented in hospital settings
