Unique level of Multi-Drug Resistance (MDR) in Pseudomonas aeruginosa Strain DEB1

Debasis Mitra | Arup Kumar Mondal | Arijit Mukhopadhyay

Abstract: Pseudomonas aeruginosa is an opportunistic pathogen, a common cause of nosocomial infection havingn the ability to Multi-Drug Resistance (MDR). We have isolated the test bacterial strain from waste water. The isolated strain is identified by molecular marker method (16s rRNA sequencing) and Pseudomonas aeruginosa strain DEB1 (KF195926) has been deposited in Gene bank nucleotide sequence database. This article aims to summarize the antibiotic resistance profile (Disc diffusion method) of P. aeruginosa strain DEB1. It showed a unique level of natural MDR on twelve numbers of antibiotics. The study also focussed on the effect of temperature (4-600C) and PH (5-9) on the growth pattern of this strain. P. aeruginosa is widely known for two distinctive properties: the production of the blue-green pigment, pyocyanin, and the ability to lyse or to inhibit the growth of other bacteria. This strain highly efficient to produce extracellular blue-green pigment within 24 hours in KingB medium. The study includes experiments to determine the effect of various media on pigment production.
