Acinetobacter baumannii: Association between Environmental Contamination of Patient Rooms and Occupant Status

Abstract

We aimed to determine the association between the presence ofAcinetobacter baumanniiin patient rooms and the carrier status of the occupants. Fifty-six (39%) of 143 rooms withA. baumannii– positive patients had results positive forA. baumannii.Only 49 (10%) of 485 rooms withA. baumannii-negative patients were positive (odds ratio, 5.72 [95% confidence interval, 3.66–8.96];P< .0001). Clinical and environmental isolates shared pulsed-field gel electrophoresis patterns.
