Bacteriological findings in the transtracheal aspirate from patients with acute exacerbation of chronic bronchitis (original) (raw)
Summary
Transtracheal aspirates from 87 patients with acute exacerbations of chronic bronchitis who had received no recent antibiotic treatment were examined. A single bacterial species was found in 83% of positive cultures. Predominant pathogens were_Haemophilus influenzae_ and_Streptococcus pneumoniae_ which occurred jointly or separately in 50% of positive cultures. Bacteria traditionally considered as non-pathogenic for the lower respiratory tract also appeared to play an aetiological role.Enterobacteriaceae and anaerobes were infrequent. No bacterial growth was found in 11 cases.
Zusammenfassung
Das Transtrachealaspirat von 87 Patienten mit antibiotisch unbehandelter, akuter Exazerbation einer chronischen Bronchitis wurde bakteriologisch untersucht. In 83% der positiven Kulturen wurde nur eine Bakterienart nachgewiesen. Die weit vorwiegenden Befunde waren_Haemophilus influenzae_ und_Streptococcus pneumoniae_ die, vereinzelt oder gemeinsam, in 50% der positiven Kulturen auftraten. Auch Bakterienspezies, die in bezug auf die Luftwege gewöhnlich als nicht pathogen betrachtet werden, waren anscheinend von ätiologischer Bedeutung.Enterobacteriaceae und Anaerobier wurden selten isoliert. In 11 Fällen wurden keine Bakterien nachgewiesen.
