Bacterial Contamination between Computers in Computer Labs

Abstract

This study was conducted to identify the role of computers in transmitting bacterial infections to users of
these devices. The bacteria on the surface of computers (mouse and keyboard) were isolated to identify their
genotypes and their effects on the health of their users. The study sample included 100 samples divided as
follows: 10 computers for each section of the Technical Institute in Baquba. Wipes grew on the following
circles: Macconkey agar, Nutrient agar, Blood agar for its study and recognition of its shape and was dyed
with chrom. The most common species in the studied samples were Staphylococcus spp. The prevalence of
Gram-positive spherical bacteria on the surface of computers (mouse and keyboard) was higher than that
of Bacillus and Gram negative bacteria. (192) isolates of computers and the percentage of contamination of
the computer keyboard higher than the percentage of contamination of the mouse as the number of isolates
of the phenomenon of swabs taken from the keyboard (117) and the proportion of about (60.9%) while the
number of isolates visible from swabs taken from the mouse (75%). The percentage of bacteria found on
the surface of the keyboard is more numerous than the bacteria on the mouse surface. The results of the
antibiotic sensitivity test showed that all of these species were sensitive to antibiotics but to varying degrees.
