Assessment of Some Selected Automated Teller Machines in Kaduna Metropolis for Pathogenic Bacteria Contamination (Published)
Selected Automated Teller Machines in Kaduna Metropolis were assessed for pathogenic bacteria contamination. Pathogenic bacteria such as Escherichia coli, Pseudomonas aeruginosa, Shigella dysenteriae, Salmonella typhimurium, Staphylococcus aureus and Klebsiella pneumonia were isolated using standard methods. Kano Road and Ahmadu Bello Way had the highest number of isolates as well as sample size because of the concentration of the banks around these roads and the influx of people within and around this area who do business on a daily basis. K. pneumoniae had the largest percentage of isolates with 46 (23.0%), followed by S. dysenteriae with 37 (18.50%). S. aureus, S. tyhimurium, and P. aeruginosa had 33 (16.50%), 32 (16.0%) and 29 (14.5%) respectively while E. coli had the smallest percentage of isolates with 22 (11.0%). The correlation coefficient (r) of 0.60 obtained showed that there is a strong relationship between the isolated pathogenic bacteria and the Automated Teller Machines.
