[Comparison between the bacterial flora airways and of the lung tissue].
In 44 patients tracheotomized and under mechanical ventilation bacteriological studies were carried out, inmediately after death, in bronchial secretions and in a small piece of lung obtained by thoracotomy. The more frequently found bacterium in bronchial secretions or the lung was the Pseudomona aeruginosa (Table 1). In order of decreasing frequency: Klebsiella, Staphylococcus, Proteus, etc. were found in the lung while in bronchial secretions the order was inverse by predominance of Proteus. Total bacteriological coincidence was found in 14 cases while it was partial in 8 more patients where another bacterium was added in bronchial secretions. Bacteria were different in 6 cases (Table 2) in 4 of them: staphylococcus was obtained in the lung while Pseudomonae, Proteus and Klebsiellae were present in bronchial secretions (Table 3). In 16 cases cultures of the piece of lung taken were negative. Not taking into account these last ones, it is possible to conclude that from the therapeutic stand point culture of bronchial secretions was useful in antibiotic selection in 22 out of 28 cases.
