Cedecea davisae’s Role in a Polymicrobial Lung Infection in a Cystic Fibrosis Patient

Abstract

Chronic airway colonization and infection are the hallmark of cystic fibrosis (CF).Staphylococcus aureus, Pseudomonas aeruginosa, andBurkholderia cepaciaare well-documented bacterial culprits in this chronic suppurative airway disease. Advanced molecular diagnostics have uncovered a possible role of a larger group of microorganisms in CF.Cedeceais a member of the family Enterobacteriaceae and is an emerging pathogen. We present a case of a polymicrobial healthcare-associated pneumonia in a CF patient caused byCedecea davisae, among other bacteria.
