Abstract

Chronic airway colonization and infection are the hallmark of cystic fibrosis (CF). Staphylococcus aureus, Pseudomonas aeruginosa, and Burkholderia cepacia are 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. Cedecea is 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 by Cedecea davisae, among other bacteria.
