Pneumococcal Bacteremia with Especial Reference to Bacteremic Pneumococcal Pneumonia

Abstract
The biology of infections caused by the several pneumococcal types varies and the dissimilarities are reflected by differences in invasiveness and mortality in both untreated and treated infections. Some persons are at higher risk of death from pneumococcal infections than others and cannot be prevented from dying either by antimicrobial therapy or by measures now available to correct the physiologic derangements of infection. Evidence extant suggests strongly that the morbidity and mortality from pneumococcal infection can be reduced significantly by prophylactic vaccination of persons at high risk with a preparation of six pneumococcal capsular polysaccharides. There is need for the reinstitution of capsular typing and of other bacteriologic techniques employed formerly for better understanding and control of the infections.
