Microbiological investigations.

Data are presented as mean (percentage) mPCR, multiplex Polymerase Chain Reaction; a In 19 patients, 21 etiologic agents were identified 26 times, by positive blood culture (n = 4), bronchoalveolar lavage (n = 1), bronchial aspirate (n = 2), distal protected sample (n = 4), sputum (n = 6), and by urine antigen testing (Streptococcus pneumoniae (n = 4); Legionella pneumophila (n = 5)). b Bacterial culture of respiratory sample is defined as a bacterial culture of bronchial aspirate or distal protected sample or bronchoalveolar lavage or sputum. c Mycoplasma pneumoniae was tested in 89/123 patients (72.4%), when combining patients who underwent either serologic tests or nasopharyngeal swab mPCR. d Chlamydia pneumoniae was tested in 90/123 patients (73.3%), when combining patients who underwent either serologic tests or nasopharyngeal swab mPCR.
