Atypical pneumonias caused by Legionella pneumophila, Chlamydophila pneumoniae and Mycoplasma pneumonia

Comparison of Sputum and Nasopharyngeal Swab Specimens for Molecular Diagnosis of Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella pneumophila

BACKGROUND The identification of molds in clinical laboratories is largely on the basis of phenotypic criteria, the classification of which can be subjective. Recently, molecular methods have been introduced for identification of pathogenic molds in clinical settings. Here, we employed comparative sequence analysis to identify molds. METHODS A total of 47 clinical mold isolates were used in t...

Three cases of atypical pneumonia caused by Chlamydophila psittaci.

Psittacosis is a zoonotic disease caused by Chlamydophila psittaci. The most common presentation is atypical pneumonia. Three cases of pneumonia of varying severity due to psittacosis are described. All patients had a history of avian contact. The diagnosis was confirmed by molecular detection of Chlamydophila psittaci in respiratory specimens. The cases showed good recovery with doxycycline tr...

Severe late-onset nosocomial pneumonia caused by Chlamydophila pneumoniae.

We report two cases of severe late-onset nosocomial pneumonia caused by Chlamydophila pneumaniae. The clinical course of the disease in these patients suggests that nosocomial pneumonia caused by this agent can lead to profound respiratory insufficiency and acute respiratory distress syndrome, particularly in patients with significant comorbidities and during the postoperative period. Intraveno...
