The present study conducted to examine bacterial contamination of mobile phones and their antibiotic
susceptibility patterns. Surfaces of 300 mobile phones of randomly chosen from students, employees and lecturer
at campus of University of Kufa were aseptically swabbed. Serial dilution was utilized as a part of bacterial
quantification with blood and MacConkey agars. Gram stain and API20 system were applied in identification
and disc diffusion method employed in antibiotic sensitivity testing. There was 86% of the surfaces mobile
phone contaminated with a mean bacterial number of 10.11x106CFU/mL with a total of 10 bacterial species
isolates. Bacterial isolates include Staphylococcus epidermidis and Bacillus cereus (40%) each one, which were
the dominant isolates, followed by Staphylococci aureus (20%), Streptococcus pneumoniae (12%), Escherichia
coli (9%), Enterococcus feacalis (9%), Klebsiella pneumoniae (5%), Pseudomonas aeruginosa (3%), Salmonella
spp. (2%), Shigella spp. (2%).Antimicrobial susceptibility testing demonstrated that isolated bacteria appeared
with different resistant patterns. So that mobile phone becomes a potential source of disease transmission
requiring utilization of individual cleanliness as preventive methods. |
