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 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 کاملNeuraminidase activity in Streptococcus sanguis and in the viridans group, and occurrence of acylneuraminate lyase in viridans organisms isolated from patients with septicemia.
The enzyme neuraminidase (EC 3.2.1.18) was found to be strongly active in different types of Streptococcus sanguis and S. viridans, and, in addition, the occurrence of the enzyme acylneuraminate pyruvate lyase (EC 4.1.3.3) was described in S. viridans. The enzyme-active bacteria strains were isolated from blood cultures of patients with septicemia. Whereas S. sanguis lost its strong neuraminida...
متن کاملThe Formation of Methemoglobin by Streptococcus Viridans
Cultures of Streptococcus viridans when brought into contact with red blood corpuscles have the power of transforming oxyhemoglobin into methemoglobin. The reaction occurs only in the presence of living streptococci when they are able to carry on their metabolic activities. The intensity of the reaction runs roughly parallel with the period of growth and multiplication of the bacteria and gradu...
متن کاملBlood Chemical Changes in Experimental Streptococcus Septicemia
The following changes have been found to occur in rabbits given fatal intravenous doses of Streptococcus hemolyticus: The blood sugar concentration drops at a constant rate throughout the disease, but does not reach a condition of hypoglycemia. Glycogen is present in the liver at death. The CO(2) capacity is lowered markedly at first, then returns to a somewhat higher level, at which it continu...
