Pathologic Anatomy and Bacteriology of Influenza

In this paper the results of our studies on the pathologic anatomy and bacteriology of influenza during the epidemic of the fall of 1918 at Camp Zachary Taylor and Camp Knox, Kentucky, are prescnted. Necropsies, with routine bacteriologic cultures, were performed throughout the entire epidemic, so that a fairly definite picture of its various stages could be formed. The present investigation has been limited to 126 definitely proven fatal cases of influenza. These were selected from a considerably larger number by ruling out all patients who clinically gave evidence of preexisting disease, such as tuberculosis, measles, etc., or where such evidence was found at the ṇecropsies. Thus the morbid changes encountered may be looked on as primarily representing the end-results of the virus of influenza and its commensals. No attempt has been made to give even a nearly complete bibliography, but for the purpose of comparison a limited number of
