Microbial Etiology of Pneumonia: Conclusion

When the risk of dying is great, improper antimicrobial coverage during the first few days of the illness is of enormous concern, yet present diagnostic methods are so inadequate that in only a few episodes can the etiologic agent be known within 48 hs. This problem has been addressed for…

Microbial Etiology of Pneumonia: Discussion

It is clear from the study discussed here and from numerous reports in the literature that only about half of all episodes of pneumonia studied will have a specific microbial etiology determined, even though extensive diagnostic investigations will have been done. Over the years, results from expectorated sputum have been…

Microbial Etiology of Pneumonia: Community-Acquired Pneumonia

No particular bacterium predominated; 2 cases each were due to Escherichia colit Klebsiella pneumoniae, and Hemophilus influenzae. Gram-positive organisms including Streptococcus pneumoniae, Staphylococcus aureus, and Staphylococcus epidermidis accounted for 23 episodes. There were 3 patients with Mycoplasma pneumonia and 7 had influenza A virus as the only demonstrated pathogen. Despite…

Microbial Etiology of Pneumonia: Results

A total of 232 patients having 238 episodes of clinical pneumonia were admitted to the study. After review of each episode, 35 patients who had 36 episodes were diagnosed during life as having another disease. This left 197 patients with 202 pneumonia episodes who could be evaluated. Their ages ranged…

Microbial Etiology of Pneumonia: Diagnostic studies

We also tested for agglutinating antibodies against FranciseUa tularensis and LegioneUa pneumophila serogroups I-VI and Lmicdadei. Some patients were subjected to additional invasive diagnostic studies as directed by the attending physician. These specimens obtained by percutaneous needle aspiration of the lung or by thoracocentesis were cultured in the same manner…

Microbial Etiology of Pneumonia: Pevelopment of pneumonia

The study was done at the McClellan VA Medical Center, where all patients hospitalized on the medical service were prospectively evaluated on admission and throughout their hospital course for the development of pneumonia. Each patient identified with clinical pneumonia was evaluated within 24 h for inclusion in the study. To…

Microbial Etiology of Pneumonia: Technical problems

Where should our investigation be focused? There seems to be no lack of potent antimicrobial agents; new agents are introduced almost every year. Prevention of pneumonia using various vaccines has received increased emphasis with a positive effect, particularly for influenza A infection. That the microbial etiology of pneumonia should be…
