Germ monitoring of patients, staff and environment in reverse isolation.

: To estimate the efficiency of germ-poor for patients who underwent BMT or ABMT in reverse isolation we investigated the staff, patients and the environment of the BMT unit bacteriologically and mycologically between 1/85 to 3/87. On patient's body surface gram-negative germs were not estimated but coagulase negative staphylococci persisted. Only in few cases aerobic spores were detectable, seldom enterococci, corynebacterium and fungi. Staff members had a distinct higher grade of contamination inside the BMT-unit but outside of isolation rooms. We found sporadically staphylococcus aureus and germs of the mouth cavity on hands and fore head. Although gram negative rods were seldom detected in environmental studies, humid regions of the ward remain to be problematic zones.
