Note 3 — THE PATHOLOGY OF THE RESPIRATORY TRACT IN INFLUENZA
Reading edition
A marked fibrinous exudate in the lower trachea with the formation of a pseudomembrane was noted by Oberndorfer (108), Lubarsch (19), Coray (28), Borst (15), and Schmorl (128). Schmorl studied the bacteria from the trachea and found in sections streptococci, pneumococci, and staphylococci, but not B. influenzæ or B. diphtheriæ.
