Microbial Contamination of Computer Keyboards and Mice in Educational, Healthcare, and Administrative Environments: A Field Study Using Laboratory and Statistical Analysis
Keywords:
Microbial contamination, Keyboards, Computer mouse, Candida, Staphylococcus, Bacillus, Infection controlAbstract
This study aims to evaluate the level of microbial contamination on computer keyboards and mice used in educational, healthcare, and administrative environments, as well as to identify the associated microorganisms and analyze the factors influencing their spread. A total of 24 samples were collected from device surfaces at the Higher Institute of Medical Technology in Sabratha using sterile swabs. Samples were cultured on different media and analyzed using laboratory techniques, including Gram staining and biochemical tests.
The results revealed that 50% of the samples were contaminated. Candida spp. was the predominant microorganism (33.3%), followed by Staphylococcus and Bacillus spp., each with a prevalence of 12.5%. Statistical analysis showed no significant differences between surface types (keyboard vs. mouse) and contamination levels (P > 0.05).
The findings indicate that electronic devices act as potential reservoirs for indirect infection transmission, particularly in shared-use environments with inadequate cleaning practices. The study recommends incorporating electronic devices into infection control protocols, promoting hygiene awareness, and implementing regular disinfection using broad-spectrum disinfectants.
