Abstract

We describe the first report of temporally related cases of Bordetella holmesii bacteremia. Demographic and clinical data were collected through chart abstraction and case-patient interviews. Twenty-two cases were identified from 6 states. Symptom onset dates ranged from April 2010 to January 2011. Median age of patients was 17.1 years and 64% had functional or anatomic asplenia. Pulsed-field gel electrophoresis profiles of a sample of isolates were identical. These cases occurred during a peak in pertussis outbreaks with documented cases of B. holmesii/Bordetella pertussis respiratory coinfection; whether there is a link between B. holmesii respiratory and bloodstream infection is unknown.
