Abstract :

Multidrug resistance in bacteria is an important phenotypic property that has complicated the treatment of infectious diseases. Klebsiella pneumoniae is a ubiquitous organism ranking next to E. coli in hospital settings. KPC-2 type beta lactamase producing K. pneumoniae is a worldwide concern as it renders carbapenems ineffective. Elucidating resistance mechanisms in these bacteria could help in identifying novel therapeutic targets. This study is a preliminary work conducted to determine the effects of meropenem on blaKPC-2 harbouring multidrug resistant clinical strain of Klebsiella pneumoniae. The analysis was performed by 2-DE of whole cell extracts of bacteria exposed to sub-lethal concentration of meropenem as compared to control. A total of 16 differentially expressed proteins were identified by MALDI-TOF which were statistically significant. The proteins involved in defence against oxidative stress and glycolytic enzymes were highly expressed in the treated condition hence revealed the important role played by these proteins in imparting resistance to bacteria under antibiotic stress. This study was an attempt to understand the changes in the proteome that collectively make bacteria tolerant to antibiotic stress.
