[Pulmonary suppurations: etiologic profile].

: The goal of this study was to determine the pathogens of the necroses of pulmonary tissue. These debilitating diseases are usually diagnosed based on clinical and radiological findings, while the more difficult microbiological diagnosis often remains uncertain. The study involved 115 patients diagnosed with lung abscess or necrotizing pneumonia; the investigations were performed in the laboratory of the "Leon Daniello" Clinical Hospital of Pneumology, Cluj-Napoca, Romania, in the period 1999-2000. The laboratory samples (sputum, transtracheal aspiration, pleural fluid, blood samples) were studied by direct microscopy and in culture. Our results concerning the pathogens are as follows: aerobes - 20 patients (17%), mixed pathogens - 57 patients (50%). We found that the most dominant pathogens from those encountered are the anaerobes (83%), which were present either alone, or in mixed infections.
