Note 5 — THE PATHOLOGY OF THE RESPIRATORY TRACT IN INFLUENZA
Reading edition
Two examples of fresh endocarditis are reported by Malloch (95) and one by Dietrich (34), all of which were due to B. influenzæ. Acute myocarditis was observed by Blanton and Irons (12) and Gruber and Schädel (50). Glaus and Fritzsche (47) report a case with multiple hemorrhages, necrosis, and leucocytic infiltration of the heart muscle and also one of Zenker’s degeneration of the myocardium. Cases of both myocarditis and endocarditis are included by Leichtenstern (82) in a review of the epidemic of 1889–1890.
