“…In our study, 25.9% of the identified isolates were S. aureus. Two other studies from Nigeria and Iran also reported 39% and 23% contamination rates of computer keyboards with S. aureus, respectively (16,19). They also pointed out that the computer emits radiation that is effective on microorganisms and that the abundance of S. aureus on the computer keyboard could be due to its high tolerance against the radiation emitted by the computer (20).…”

Background: Computers and other electronic devices are a requisite aspect of people’s lives globally for multiple purposes, including education, entertainment, and communication. Objectives: This study investigated the bacterial contamination of desktop computer keyboards (as a reservoir of pathogens) in different departments of Mazandaran University of Medical Sciences, Sari, Northern Iran, from September 2018 to February 2019. Methods: In this descriptive cross-sectional study, samples were obtained from computer keyboards with sterile swabs and cultured on blood agar and eosin methylene blue agar. Standard microbiological methods were used to identify bacterial isolates. Then, the antimicrobial susceptibility testing of the isolates was performed using the Kirby-Bauer method based on the CLSI procedure. Results: In total, 58 bacterial strains were isolated from the collected samples. The isolates included 23 (39.7%) Staphylococcus epidermidis, 15 (25.9%) Staphylococcus aureus, 14 (24.1%) Bacillus spp., 3 (5.2%) Klebsiella pneumoniae, 2 (3.4%) Pseudomonas aeruginosa, and 1 (1.7%) Escherichia coli. All Gram-positive bacteria were resistant to penicillin, whereas the most resistance rate among Gram-negative bacteria was observed against ciprofloxacin, ceftazidime, and cephalothin. Conclusions: Due to the presence of opportunistic pathogens on computer keyboards, personal hygiene and periodic cleaning of keyboards with disinfectants is necessary to prevent the further spread of these bacteria.

Currency is one of the most frequently passed items in the world. It used every day and every way, and it could act as an important vehicle for cross-contamination. This research was aimed to determine how long pathogenic bacteria can survive on currency paper, four pathogenic bacteria including E. coli, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis were provided according to laboratory standard methods. Sterile pieces of currency paper were inoculated with the pathogenic bacteria and the survival of bacteria was tested over seven days. The results showed that all tested bacteria differed in time of survival and this survives according to environmental conditions, the type of bacteria and the mode of its resistance, but they were stable and still cultivable after seven days. The second part of this research was to design a simple experimental model to check the efficacy of germicidal and attempted to use ultraviolet light radiation to evaluate the inhibitory effect of most pathogenic microorganisms on currency as a disinfectant. The results revealed that UV is an effective tool, so we recommend using it as a disinfectant for currency.
