Most of the species of bacteria found contaminating various sites within vehicles were harmless, non-pathogenic species, and are representatives of natural environmental and skin flora. Some, however, for example S aureus and S viridans, are potential pathogens. Contact with the contaminated environment, fomites, equipment, etc, will contaminate hands. The role of contaminated hands in the transmission of such infections has been well reported.1 Similarly, contaminated cleaning equipment may be to blame where bacterial counts after cleaning exceeded those before.
