ABSTRACT
Different
people from different socio-economic levels and hygiene status use the
Automatic Teller Machines (ATM) daily and increase the chances of hand-borne
transmission of microorganisms to the machine's surfaces. A TMs might be
potential areas for pathogen accumulation and they might have a role in
microbial transmission to the community. This is a cross sectional analytical
study using an average of five (5) banks automated teller machines in Umudike
(Access, Sterling, Zenith. UBA and Ecobank). Sterile cotton swabs soaked in
physiological saline was used to take swabs from the Screens, keyboards and
slits of the A TM. The swabs were dipped into a normal saline and streaked on
different selective media including nutrient agar, mannitol salt agar,
macConkey agar. The inoculated media were then incubated for 24-48 hours.
Standard biochemical tests were used to confirm the bacterial isolates. The
bacteria identified were Bacillus, Streptococcus, Staphylococcus, Salmonella,
Shigella, Pseudomonas, E.coli and Proteus with colony features, spore, gram
staining, flagella. motility, biochemical tests characteristics of each.
Staphylococcus spp has yellow colonies, gram positive, non sporeforming,
absence of flagella, non motile, catalase positive, oxidase negative, coagulase
positive and indole negative; Salmonella spp has black colonies, gram negative.
non spore-forming. no flagella. non motile, catalase positive, oxidase
negative, coagulase negative and indole negative; Streptococcus spp has small
white grey colonies, gram positive, non spore-forming. no flagella. non motile,
catalase negative, oxidase negative, coagulase negative and indole positive;
Shigella spp has creamy mucoid colonies, gram positive oxidase negative,
coagulase negative and indole negative; Bacillus is comma-shaped and sticky,
gram positive, spore-forming, has flagella, motile. catalase positive. oxidase
positive, coagulase negative and indole negative; Pseudomonas has mucoid
colonies, gram negative, non spore-forming, has flagella, motile. catalase
positive, oxidase negative, coagulase positive, and indole negative; £. coli
has pink pigment, gram negative, non spore-forming. has flagella. motile.
catalase positive, oxidase negative, coagulase negative and indole positive;
Proteus has gray white colonies. gram negative, non spore-forming has flagella,
motile. catalase positive, oxidase negative, coagulase negative and indole
negative. While the fungi identified were Yeast, Aspergillus, Penicillium,
Rhizopus. Fusarium with microscopic features and colony features. Bacteria were
dominant on the keypad because they are attached to the hands and transferred
mainly by hands on the keypad. Fungi were dominant on screen because they are
predominance on the air. Both bacteria and fungi are few on the slit. The mean
bacteria occurrence was (37.5%) in the screen with an occurrence of 37.5% in
each of the A TMs. The slit had bacteria occurrence of 30%. The gross mean
fungi occurrence were 60% on screens, 56% on the buttons and 16% on the slit
openings
