Physiological differentiation of viridans streptococci.
Twelve hundred and twenty-seven clinical isolates and eighty stock strains of viridans streptococci were tested for serological and physiological characteristics. Because the serological reactions of these strains varied, a differentiation scheme could not be based on these reactions. For the same reason, there could be no correlation of serological characteristics with physiological characteri...
متن کاملClassification and identification of the viridans streptococci.
This review traces the history of the human, nonhemolytic, or viridans, streptococci and describes improvements in their taxonomy wrought by study of their biochemical profiles and analysis of their nucleic acids. The goal was to define species on the basis of genetic relationships and to describe these species by their phenotypic characteristics so that they can be easily identified. This meth...
متن کاملAutolysis in strains of viridans streptococci.
Seven strains of viridans streptococci of the species Streptococcus sanguis, S. mutans and S. mitis were investigated for autolysis. The effect of pH, salt concentration and temperature on the autolytic process was studied in Na2HPO4/NaH2PO4 buffer. Whole cells and walls of all strains autolysed most rapidly at pH values above 7. Autolysis of whole cells of S. sanguis and one strain of S. mitis...
متن کاملPrevalence rate and antibiotic susceptibility of oral viridans group streptococci (VGS) in healthy children population.
PURPOSE The aim of this study was to evaluated the prevalence rate of oral viridans group streptococci (VGS) and their susceptibilities to some antibiotics in healthy children. MATERIAL AND METHODS Samples of pharyngeal swabs and supragingival dental plaques for microbiological studies were collected from 206 healthy children, aged 4-18 years. Additionally, 75 samples of carious lesions from ...
متن کاملInterference of antibiotics in the growth curves of oral streptococci.
The growth curve interference (GCI) induced by different antibiotics was studied using reference strains of oral streptococci. This parameter may prove to be useful in preventing subacute endocarditis of odontological origin in high-risk patients. The growth curves using different concentrations of antibiotics and with an initial optical density (OD) of 0.05 +/- 0.01 were observed until an OD o...
