Bordetella bronchiseptica in non-cystic fibrosis bronchiectasis

Abstract

Bordetella bronchiseptica is a rare pulmonary infection, often associated with zoonotic transmission. It has been described in immunocompromised patients and those with underlying pulmonary disease. However, there are no case series describing the spectrum of disease caused by Bordetella bronchiseptica in patients with non-cystic fibrosis bronchiectasis. Here, we report three cases of Bordetella bronchiseptica infection in patients with non-cystic fibrosis bronchiectasis and highlight the pathophysiology of the microbe. While the clinical presentation can be quite variable, it is important to note that Bordetella bronchiseptica can be a cause of pulmonary exacerbations and can be difficult to eradicate.
