Role of Automated Teller Machine Keypads in the Proliferation of Bacteria: A Public Health Concern

Authors: Akinnibosun FI, Adetitun JA

ABSTRACT

The role of automated teller machine (ATM) keypads in the proliferation of bacteria was investigated in this research. Isolates and their prevalence in bank ATMs in Benin City were: Klebsiella sp. (8.16%), Pseudomonas aeruginosa (7.28%), Proteus vulgaris (8.83%), Escherichia coli (12.58%), Micrococcus luteus (3.75%), Bacillus subtilis (10.15%), Staphylococcus aureus (13.46%), Corynebacteria sp. (8.60%), Staphylococcus epidermidis (19.42%) and Streptococcus pyogenes (11.58%). Total heterotrophic bacterial count (THBC) by banks ranged from 1.16±0.43 × 102 cfu/cm2 (Bank I) to 2.22± 0.58×102 cfu/cm2 (Bank K). Total coliform count (TCC) ranged from Nil (Bank B and G) to 1.37 ± 2.11×102 cfu/cm2 (Bank I). By location and time, THBC ranged from 1.27 ± 0.63×102 cfu/cm2 (UUC) to 1.60 ± 0.43×102 cfu/cm2 (ER/RR) and 1.38 ± 0.57×102 cfu/cm2 (UUC) to 1.93 ± 0.61×102 cfu/cm2 (UR) for morning and afternoon respectively. TCC ranged from 0.52 ± 0.41×102 cfu/cm2 (UR) to 1.15 ± 0.57×102 cfu/cm2 (UUC) and 0.31 ± 0.50×102 cfu/cm2 (ER/RR) to 1.46 ± 1.49×102 cfu/cm2 (UUC) for morning and afternoon respectively. From the foregoing, it is pertinent to adopt measures aimed at preventing outbreak of diseases from ATM use.
