Environmental contamination by carbapenem-resistant Acinetobacter baumannii: The effects of room type and cleaning methods.

In step-up rooms, the high number of objects contaminated combined with poor efficacy of cleaning resulted in failure to eliminate CRAB in patient units. Fluorescent gel is a poor detector of CRAB contamination. The role of aHP is still unclear. However, its use in multipatient rooms is limited because it can only be used in unoccupied rooms.
