Detection of bacteremia: technical aspects of the blood culture.

materials; well under 10% of total housekeeping costs are for the products used for cleaning and/or disinfecting floors. If disinfectant-containing products were not used in floor cleaning, it is likely that wet mops would become so contaminated during a work-shift that there might be increased rather than decreased microbial contamination after "cleaning" (and we recommend additionally that the mops be laundered and thoroughly dried daily). Some references cited in our paper "Housekeeping in operating suites," AORN Journal 21:213-220, 1975, indicate that disinfectant-containing products are more effective in reducing microbial contamination than detergents and water alone (T.S. Gable, Hospitals, 40:107-111, February 16, 1966; G.A.J. Ayliffe, B.J. Collins, E.J.L. Lowbury, Br Med J 2:442-445, 1966; W.D. Foster, Lancet, 1:670-673, 1960; and J.S. Kuipers, / Hygiene, 66:625-631, 1968).
