Primary Streptococcus viridans pneumonia.
We describe three cases of acute uncomplicated bacterial pneumonia due to viridans streptococci in previously healthy adults, which were indistinguishable from those caused by other well-known respiratory pathogens. On arrival, all of these patients were treated with IV aqueous penicillin based on Gram stain of sputum which showed predominant Gram-positive cocci in pairs and chains. These speci...
متن کاملStudies on the Serological Typing of Streptococcus Hemolyticus
The cross-reactions which interfere with satisfactory serological identification of hemolytic streptococcus are due to anticarbohydrate in the sera used for typing. This antibody can be removed easily by absorption with purified streptococcus carbohydrate, and type identification is then readily established. The serological classification of hemolytic streptococcus from throat infections contra...
متن کاملThe Localization of Streptococcus Viridans
The results of our experiments do not substantiate in full the theory of the power of selective action of Streptococcus viridans. A few strains showed a remarkable constancy in location and type of lesion, but these strains were greatly in the minority. The location of the lesions in animals seemed to bear no relation to the origin of the organism or to the lesions produced by it in the patient...
متن کاملStreptococcus Hemolyticus: A Study of Virulence *
In 1928 Duran-Reynals8 reported that vaccine virus skin infections in rabbits were intensified when the virus used was extracted from testicular tissue. This subject was rapidly developed and the agent responsible came to be designated "spreading factor." Spreading factor was reported to be present not only in organ extracts of mammalian testes, but also to a lesser degree in the kidney and ski...
متن کاملPhenotypic differentiation of Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus strains within the "Streptococcus milleri group".
A biochemical scheme was developed by which strains of Streptococcus constellatus, Streptococcus intermedius, and Streptococcus anginosus can reliably be distinguished from within the "Streptococcus milleri group." Strains identified as S. intermedius were differentiated by the ability to produce detectable levels of alpha-glucosidase, beta-galactosidase, beta-D-fucosidase, beta-N-acetylgalacto...
