Antimicrobial susceptibility pattern of Gram-negative bacteria isolated from blood stream infection from intensive care unit in tertiary care teaching hospital.

Abstract

Introduction: Blood stream infections range from self-limiting infections to life threatening 
septicaemia that requires rapid and aggressive antimicrobial treatment (1)
. Mortality due to 
blood steam infection ranges from 20% to 50%. Objectives: The present study was 
undertaken to analyse the various Gram-negative microorganisms causing blood stream 
infections and study their antimicrobial resistance patterns in a tertiary care hospital, to 
guide the clinicians for formulating antimicrobial policies for empirical therapy. 
Methodology: Blood culture was collected from 218 patients admitted in intensive care unit 
and incubated at 370
c aerobically and then subculture was made on blood agar and 
MacConkey agar on 2nd,4th and 5th day. Organisms were identified according to colony 
morphology and standard biochemical tests
