Abstract:

Antimicrobial resistance in E. coli is of major concern worldwide due to its increasing resistance to several commonly prescribed antibiotics. The aim of this study was to determine the antimicrobial susceptibility pattern of E. coli. A retrospective analysis of E. coli and their antimicrobial susceptibility was done on urine and pus samples at Subbaiah Institute of Medical Sciences, Shimoga. Antibiotic susceptibility was tested on Mueller Hinton agar by Kirby Bauer disc diffusion method. Total of 73 E. coli isolates from urine sample were studied. Females 55 (75%) were more susceptible to urinary tract infections (UTIs) than males18 (25%). Majority of the isolates were sensitive to amikacin 69 (95%), gentamicin 55 (75%) and nitrofurantoin 65 (89%). Out of 28 isolates from pus sample, 19 (68%) were from males and 9 (32%) from females. Most of the isolates were sensitive to amikacin 25 (89%), gentamicin 21 (75%), meropenem 21 (75%) and chloramphenicol 20 (71%). Resistance rates to ampicillin and cephalosporins were high. Since most isolates were sensitive to amikacin and gentamicin in both samples, they are considered as appropriate antibiotics for treatment of E. coli infections.
