[Bacteria studies on 32 patients with acute inflammatory pneumopathies].
Thirty two patients admitted to the "Gral. Calixto García" Hospital for infectious pneumonopathies acquired outside and within hospital were studied. Each patient underwent 8 blood cultures in order to determine most frequent causal agents in our environment thus enabling the institution of an adequate antibiotic therapy. Grampositive germs, specifically staphylococcus, prevailed in extra hospitalary bronchopneumonopathies and gramnegative germs, specially Klebiella, prevailed in the case of intra-hospitalary infections. The negative effect of the antimicrobial therapy prior to sample obtention on the results of bacterial examinations is stressed.
