Mycobacterium chelonei isolation from broncho-alveolar lavage fluid and its practical implications

J Hosp Infect. 1990 Oct;16(3):257-61. doi: 10.1016/0195-6701(90)90114-4.


Mycobacterium chelonei was isolated from the broncho-alveolar lavage fluid of seven patients on eight occasions over a 6-month period. The same bacterium was identified in the hospital water supply. Despite the use of a recommended disinfection procedure, it proved impossible to eradicate the organism until the bronchoscopes were treated with ethylene oxide and the use of tap water in rinsing was abandoned.
