3.0 RESULTS

The average Staphylococcus Aureus inoculum per key was 596,000 organisms expressed as colony
forming units per key.

Results obtained after sanitising the keyboards are shown in the table in Appendix 1.

The keyboards were tested after the sanitisation procedure. They were found to function satisfactorily.

4.0 CONCLUSIONS

1. All the treatments significantly reduced the levels of Staphylococcus Aureus inoculated under the

keyboards. The antibacterial washing up liquid gave the lowest reductions averaging 98.32% per
keyboard. Presept at 1000ppm (the recommended level) gave the best results with 100% kill of
Staphylococcus Aureus being achieved for all inoculated keyboards.

2. Washing in water reduced the levels of Staphylococcus Aureus by 86.29%. This showed that physical

washing removed most of the bacteria but that a chemical disinfectant was essential to ensure
optimum sanitisation.

3. These results suggest that the use and regular disinfection of SpillSeal keyboards within hospital

environments such as the NHS could assist in reducing the spread of MRSA.
