Assessment of Microbial Contamination on Keyboards and Mice of Computers in Administrative Office in Surman City
Year: 2024
Type: article
Abstract: This study aimed to assess the level of microbial contamination on keyboards and mice used in administrative office in Sorman City. Samples were collected from 14 keyboards and 14 mice. Microbial analysis involved isolating and identifying bacteria using microscopic, cultural, and biochemical tests. A total of 28 samples were analyzed, revealing contamination with various bacteria. Staphylococcus aureus was the most prevalent, found in 96.42% of samples, with a higher contamination rate on keyboards (100%) compared to mice (92.85%). Other bacteria isolated included Staphylococcus epidermidis (28.57%), Streptococcus species (42.85%), Escherichia coli (14.28%), Klebsiella species. (10.71%), and Salmonella species. (21.42%). The high contamination rates, especially for Staphylococcus aureus, suggest that keyboards and mice are significant reservoirs for pathogens. Staphylococcus epidermidis and Streptococcus species were also commonly found, indicating potential routes of infection through contact with contaminated surfaces. Gram-negative bacteria such as Escherichia coli, Klebsiella species., and Salmonella species. were less prevalent but still notable, potentially due to fecal contamination or food residues. The study highlights the critical need for regular cleaning and disinfection of computer equipment to reduce microbial contamination. Improved hygiene practices are essential to prevent the spread of infections in office environments.
