Coxiella burnetii and acute exacerbations/infections in patients with chronic lung disease.
The aim of the present study was to determine the incidence of Q fever in patients with an acute exacerbation of a chronic lower respiratory tract infection. Eighty patients treated for acute exacerbation of chronic lower respiratory tract infections during a 30-month period were studied. Q fever was diagnosed by ELISA. Two elderly woman with pre-existing bronchiectasis (2.5%) were diagnosed as having an acute infection by Coxiella burnetii. The acute illness was considered to be a result of mixed infection with Pseudomonas aeruginosa and Haemophilus influenzae with C. burnetii. Co-infection with C. burnetii can occur during a bacterial exacerbation of a chronic lower respiratory tract infection.
