Burkholderia cepacia-contaminated dentures possibly cause pneumonia

Abstract

We report a case in which a patient was suspected of developing pneumonia due to wearing dentures that were immersed in a storage solution contaminated with 3.0 × 108 colony-forming units (cfu)/mL of Burkholderia cepacia. It is highly possible that the contaminated denture solution entered the trachea and caused the pneumonia, possibly due to the prolonged supine positioning of the patient. We demonstrated that B. cepacia isolated from the sputum and B. cepacia isolated from the denture storage solution had the same DNA fingerprint, and that the patient recovered from pneumonia after stopping the use of dentures. These findings suggest the storage solution as the main source of infection. HIGHLIGHTS Commercially available denture cleaning solution was found to harbor viable bacteria such as Burkholderia cepacia when used by a patient in a hospital.; Compromised hosts are susceptible to infections such as pneumonia through use of denture solutions harboring bacteria.;
