THE FATE OF ORALLY ADMINISTERED SOLUBLE SPECIFIC SUBSTANCE OF PNEUMOCOCCUS TYPES I, II AND III
1Department of Biological Chemistry, College of Physicians and Surgeons, Columbia University, and the Bureau of Laboratories, Department of Health of the City of New York, New York.
Abstract:
1. Rats, when fed the soluble specific substance of Types I, II and III pneumococcus, excrete a very large proportion in the feces. 2. Following ingestion of these substances, tests sensitive enough to detect 1 part in 2,000,000 of serum, and 1 part in 3,000,000 of urine, were negative. 3. The polysaccharide of Type I, when recovered from the feces, is as active an immunizing agent as it was originally.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Atypical Pneumonia
Pneumonia III: Complications and Assessment
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
