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.
