- Microorganisms identified on computer keyboards
- Anderson, Glenn; Palombo, Enzo A.
- The keyboards of multiple-user (student) and single-user (staff) computers located on a university campus were sampled to assess microbial contamination. Ten keyboards were sampled at random from 3 separate multiple-user student computer laboratories on the Hawthorn campus of Swinburne University of Technology in Melbourne Australia, at least 12 hours after the laboratories were last occupied by students. Five single-user computer keyboards located in staff offices were also sampled. All computers had been in use for a period of 1 to 3 years. To obtain an estimate of the total level of microbial contamination, a contact agar plate containing 4 cm2 of Plate Count Agar (PCA; Oxoid, Basingstoke, UK) was directly contacted with an area of the keyboard that included the space bar. These plates were incubated at 30 degrees Celsius for 48 hours. To determine the types of microorganisms present, the remainder of the keyboard was sampled with a moistened sterile cotton swab, which was then placed into 4 mL of Tryptic Soya Broth (Oxoid) and incubated at 30 degrees Celsius for 48 hours.
