| Abstract: | In this study a participation of anaerobic bacteria in respiratory tract diseases is presented. Bronchial washings collected by ++fibrobronchoscope constituted material for the study. Immediately after collection the material was plated onto two media for aerobic bacteria (hemomedium) and anaerobic bacteria (anaeromedium). Then, the samples were centrifuged and a sediment was plated on solid media suitable for aerobic and anaerobic bacteria. Bacterial anaerobic isolates were identified by using API 20E and their sensitivity to antibiotics was tested. From the material described above the most frequently isolated anaerobic bacteria were such as: Streptococcus intermedius, Bacteroides melaninogenicus, Veilonella sp. Among aerobic bacteria the most frequently isolated were Gram-negative rods, Streptococcus faecalis, Branhamella catarrhalis. It is worth to underline that in about 25% of cases anaerobic bacteria were the only isolates. |
