“…With a few exceptions, the analysed ATMs were not highly contaminated, compared with some others studies. Tekerekoğlu et al [32] found higher values of contamination on ATMs in Turkey with CNS between 1.5 × 10 3 -1.2 × 10 4 CFU/mL and E. coli between 10 3 -10 4 CFU/mL. Saroja et al [9], in India, showed a total microbial load ranging from 4.0 × 10°to 1.9 × 10 5 CFU/mL and presence of E. coli and Klebsiella spp.…”

Automated Teller Machines (ATM) are likely to be contaminated with various microorganisms because of their contact with the hands of many users daily. The main objective of this study was to investigate ATMs as a potential source of bacterial contamination. This study was conducted in the Metropolitan Area of Porto, in which 50 swab samples were cultured on selective media. Some isolates were identified based on colonial, morphological and biochemical characteristics. Susceptibility to several antibiotics was also evaluated for each isolated organism. Most contaminated ATMs had high numbers of Enterobacteriaceae and Enterococci. Staphylococci and Enterobacteriaceae were the most prevalent bacteria found. The recovered bacterial isolates varied in their antibiotic resistance pattern; Staphylococcus spp. demonstrated the most resistant profiles. With this pioneering study in Portugal, it was demonstrated that although ATMs in metropolitan area of Porto were not highly contaminated, some potentially pathogenic bacteria were present and resistant to some commonly used antibiotics.

The metallic keyboards of automated teller machines situated within Calabar metropolis were investigated for microbial contamination due to their vast dermal contact by multiple users. Swab sticks soaked with normal sterile saline were used to collect specimens from the keypads. Isolation was done on nutrient agar and eosine methylene blue (EMB) for bacteria and Sabouraud dextrose agar for fungi using standard microbiological procedures. Identification of microorganisms was done using colonial, microscopic and biochemical characteristics. The results reveal that these machines that serve as cash dispensing device can be a potential disease dispensing machines as samples analyzed revealed bacterial isolates such as Staphylococcus spp (32%)), Bacillus spp (24%), Escherichia spp (20%), Pseudomonas spp (18%) and Salmonella spp (6%) while fungal isolates of the samples analyzed include microorganisms such as Rhizopus spp (56%), Aspergillus spp, (25%) and Penicillium spp (19%). These findings necessitate the need for adequate personal hygiene by users and frequent routine cleaning of these machines by the bank's authorities is highly recommended.
