PREVALENCE OF MULTI DRUG RESISTANT STRAINS ON TOUCH SCREEN OF AUTOMATED TELLER MACHINE
Journal Title: Asian Journal of Pharamceutical and Clinical Research - Year 2015, Vol 8, Issue 2
Abstract
Multiple drug resistant (MDR) bacteria have spread globally even on non-porous surfaces such as mobile phones, computers, public telephone booths,keypads and touch screens of automatic teller machine (ATM). In this study, occurrence of different groups of MDR bacteria from metallic keypad andtouch screens of ATM machine was examined. The samples were collected from different ATMs located in Vellore, Tamil Nadu. Swabs were taken from47 ATMs and 488 isolates were identified as Escherichia coli (49%), Klebsiella sp., (30%), Pseudomonas sp., (16%), Acinetobacter sp., (3%) and Proteussp., (1%) and they were subjected to antibiotic susceptibility testing with ampicillin, cefotaxime, ceftriaxone, ceftizidime and meropenem of which 46isolates showed high level of resistance toward cefotaxime, and meropenem by plate assay. Further polymerase chain reaction amplification of NDM-1and CTX-M genes for all 46 isolates showed no amplified product, which showed the possibility for the presence of other types of extended spectrumβ-lactamases or metallo beta-lactamase. Our results showed the prevalence of MDR bacteria in ATM centers and most importantly awareness towardthe public regarding the spread of pathogenic bacteria in the environment.Keywords: Multiple drug resistance, Automatic teller machine centers, Public health, Antibiotic susceptibility pattern, Resistance gene.
