Gram negative pathogens acts as a significant etiological agent in causing both hospital and community acquired infections for the past few decades. Various resistance mechanisms, especially β-lactamases triggered extensive use of β-lactams. Carbapenems stands as the last resort to save many life threatening diseases. To prevent extensive Carbapenemases dissemination, this study was aimed to know the in vitro susceptibility pattern of Cefepime/tazobactam with carbapenems and other BL/BLI combinations. Between January and December 2015, with 947 non-repetitive Gram negative isolates from various respiratory samples (sputum, broncho-alveolar lavage, pleural fluid, endotracheal aspirates and throat swabs) this prospective study was done in a tertiary care hospital, Puducherry. Isolates were identified and antibiotic susceptibility testing was done with Cefepime/tazobactam and its results were compared with carbapenems and other BL/BLI combinations. Out of 947 isolates, E. coli (44%) was the predominant isolate identified, followed by Klebsiella spp. (27%) and others. The sensitivity pattern of all our Gram negative isolates towards Cefepime/tazobactam ranged from 59% to 100%. Towards carbapenems it ranged between 68%-100% and for other BL/BLI combinations 47%-100% susceptibility was observed. To overcome this emerged β-lactamase enzymes in hospital and community settings, appropriate and adequate antibiotic practices is needed. As there are very few new antibiotics in the pipe-line, antibiotic restriction policy will definitely reserve the high-end antibiotics for the future. We conclude that Cefepime/tazobactam will be a challenging combination almost equal to carbapenems and far better than other BL/BLI combinations in the practice.
