Microbiological survey of automated teller machines (atm) in Calabar metropolis

The Key pads of seventy four (74) Automated Teller machines (ATMS) were examined in Calabar Metropolis to determine the public health implications of microorganisms isolated from the machines and their potentials as reservoirs of microbes.  Swab sticks dipped in sterile peptone water and swabbed on the ATM keypads were cultured, physiological and biochemical analysis carriedout to identify the organisms.  The results showed that the ATM keypads harbored microbes.  Fifty two (70.3%) of the ATM sampled were contaminated with various microbial pathogens including:     Coagulase negative staphylococci 22 (38.5%), Staphylococci aureus 12(21.1%), Enterococci 4 (4.7%), Escherichia coli 4(4.7%), Klebsiellaspp 2(3.8%).  Others were Aspergillusspp 3(5.8%), Rhizopus 3 (5.8%) and penicilliumSpp 2(3.8%).  Parasites were not detected.  Greater hygiene measures especially regular hand-washing before and after ATM use is advocated.
