Prevalence of Nonfermentative Gram Negative Bacilli In Seriously ill Patients With Bacteraemia.

Bacteraemia due to nonfermentative gram negative bacilli appears to be increasing in frequency particularly in hospitalized patients with severe underlying illness. A total of 159 (79.50%) organisms were isolated from blood cultures of 200 seriously ill patients. Out of these, 73 (45.91%) were nonfermentative gram negative bacilli. Pseudomonas aeruginosa was the commonest isolate (32.88%) followed by Acinetobacter spp. (23.28%) and Burkholderia cepacia (10.96%). Analysis of antimicrobial susceptibility testing showed multidrug resistant pattern with majority of the isolates being resistant to three or more drugs.
