ROLE OF STREPTOCOCCI IN PHEUMONIA  19R5, p. 397


  Rosenow and Sturdivant identified a "somewhat peculiar green-


producing streptococcus or diplostreptococcus ....  ...study of the


sputum and other material [from patients during epidemic of


influenza and accompanying pneumonia] shows that of all the


bacteria isolated, the somewhat peculiar green producing


streptococcus is the most important.  This organism is present in


large numbers at the very outset of symptoms of influenza and of


the accompanying pneumonia; it is commonly present after death."


  The authors reported that the mortality rate in a group


inoculated three times with mixed vaccine which included this


streptococcus was 1/5 that of uninoculated persons.
