Introduction: Non fermentative Gram negative bacilli (NF GNB) are being increasingly isolated from patients admitted in hospitals. Most of these isolates are multidrug resistant (MDR). Methods: Over a period of one year, all clinical samples were processed and NF GNB was identified up to species level following conventional method. Antibiotic sensitivity test of the isolates were done following clinical and laboratory standard institute (CLSI) guidelines. Results: Out of 1498 clinical specimens, 320 (21.36%) isolates were identified as NF GNB. Maximum number of samples was blood, 90(28.12%), followed by pus, 84 (26.25%). Pseudomonas aeruginosa (P aeruginosa) was the commonest isolate, 192 (60%), followed by Pseudomonas species (P species), 58 (18.12%) and Acinetobacter baumannii (A baumannii), 46(14.37%). All isolates were MDR and were sensitive to polymyxin B, colistin and tigecycline. Conclusion: Multidrug resistant NF GNB was not uncommon in our hospital. All isolates were sensitive to polymyxin B, colistin and tigecycline. Indiscriminate use of antibiotics against these organisms should be avoided.
