Abstract

Introduction: Community-acquired pneumonia constitutes a major health problem worldwide. Objective: to determine the bacterial spectrum in patients hospitalized for pneumonia in a local context. Method: The results of 208 blood cultures, 69 sputum cultures, and 8 samples of respiratory secretions and lung tissue obtained postmortem were analyzed. The positivity index was determined for each method used, as well as the frequency of the isolated germs.
Results: The positivity rate for respiratory secretions (postmortem) was 87.5%, lung tissue 75%, sputum 37.6%, and blood culture 10.6%. The isolates of Klebsiella pneumoniae (20) and Streptococcus pneumoniae (19) represented 64% of the total isolates.
Conclusion: superiority of sputum culture over blood culture was verified in terms of probability of microbiological isolation. The importance of Streptococcus pneumoniae and Klebsiella pneumoniae as causes of community-acquired pneumonia was confirmed.
