Community-acquired pneumonia in patients with and without chronic obstructive pulmonary disease.

Purpose: The purpose of this study was to analyse the possible differences, especially those regarding mortality, between patients hospitalized for community-acquired pneumonia (CAP) with and without chronic obstructive pulmonary disease (COPD), and the risk factors related to mortality in the COPD group.

Methods: 710 patients with CAP were included in a prospective multicenter observational study. 244 of the patients had COPD confirmed by spirometry.

A rare case of lung coinfection by Streptomyces cinereoruber and Haemophilus influenzae in a patient with severe chronic obstructive pulmonary disease: characterization at species level using molecular techniques.

Streptomyces cinereoruber isolated from a patient with severe respiratory failure that could not be identified by culture was correctly identified at the species level by comparative sequence analysis of 16S rDNA and the hypervariable alpha-region of 16S rDNA. Restriction fragment length polymorphism, morphologic, and biochemical characteristics have confirmed their identity.
