Abstract:

The role of currency as reservoirs of pathogenic bacteria and UV light to disinfect the contaminated notes was evaluated. Two hundred currencies of different denomination were collected from different places from central part of Karnataka. The sterile swab was rolled over the currency and dipped in a falcon tube containing 10 ml of brain heart infusion broth. After 24 hours, subculture was done on Blood agar, Mac Conkey agar plates and SDA tube. After incubation for 24-48 hours, plates were examined for the growth and microorganisms were identified by standard microbiological techniques. Anti-microbial susceptibility test was done as per CSLI guidelines. To disinfect currency, the notes were exposed to UV light inside the laminar air flow for different time intervals and the currencies were subjected for culture to evaluate the efficacy of disinfectant. Three hundred and seventeen organisms were isolated from the currencies. Mixed contamination was observed in a higher percentage 60% (120/200) of tested notes. Bacillus species was the predominant bacteria grown followed by diphtheriods, CoNS, Staphylococcus aureus. Among the fungus yeast, Rhizopus sps and Aspergillus sps was isolated. Bacteria isolated were resistant for more than 2 class of antibiotics and hence all the isolates were multidrug resistant. Ten out of 26 Staphylococcus aureus were methicillin resistant and all the MRSA strains were sensitive to Clindamycin, Linezolid and Vancomycin. UV light was very effective in disinfecting all the currency notes at 30 mins of exposure. The transmission of pathogenic drug resistant bacteria through currency notes is well documented. Our study highlights the need for the public awareness regarding hygiene to be followed after any form of transaction and also banks to explore the various possibilities to disinfect the currencies.
