Patients with Acinetobacter baumannii bloodstream infections are colonized in the gastrointestinal tract with identical strains
In this study, we identified critically ill patients with Acinetobacter baumannii bacteremia and examined perirectal surveillance cultures for the presence of genetically related A baumannii strains using pulsed-field gel electrophoresis to determine whether gut colonization preceded clinical infection. Seven patients with imipenem-resistant A baumannii bacteremia were identified from January to June of 2008. Six of 7 (86%) patients were colonized in the gastrointestinal tract with genetically similar strains preceding their bacteremia.
