Emergence of multi drug resistant strains of E. Coli isolated from urinary tract infection in namakkal.

ABSTRACT

In this study we evaluated the multi drug resistant strains of Escherichia coli isolated from urinary tract infection in different age groups in Namakkal. Totally 153 isolates of E.coli were obtained from 700 urine samples. Present study indicates that there is a high prevalence of multidrug resistant E. coli in female 24.34% followed by male 18.14%. After confirmation, isolates were performed to resistance patterns of different antibiotics were determined by standard disk diffusion method. The antibiogram patterns of the isolates showed a high percentage of multidrug resistance to cephodoxime, Novobiocin and vancomycin which was repeated to most of the isolates. Fifty resistance patterns were recognized among the MDR strains. This study revealed that E. coli was the predominant bacterial pathogen of community acquired UTIs in Aligarh, India. It also demonstrated an increasing resistance to number of antibiotics. This study is useful for clinician in order to improve the empirical treatment.
