Outbreak of Nosocomial<i>Burkholderia cepacia</i>Infection and Colonization Associated With Intrinsically Contaminated Mouthwash

Abstract

From August 1996 through June 1998, 69 ventilated, intensive care unit patients at two Arizona hospitals had nosocomial respiratory tract cultures positive for Burkholderia cepacia. Intrinsically contaminated alcohol-free mouthwash was identified by pulsed-field gel electrophoresis as the source of the outbreak.
