Mannosidase production by viridans group streptococci.
The production of mannosidase activity by all currently recognized species of human viridans group streptococci was determined using an assay in which bacterial growth was dependent on the degradation of the high-mannose-type glycans of RNase B and subsequent utilization of released mannose. RNase B is an excellent substrate for the demonstration of mannosidase activity since it is a glycoprote...
متن کاملA role for immunoglobulin G in donor-specific Streptococcus sanguis-induced platelet aggregation.
There is increasing evidence for a relationship between bacterial infections and several cardiovascular disorders. Although the precise mechanism(s) underlying this association is unknown, the direct activation of platelets by bacteria is one possibility. Individual strains of S. sanguis activate platelets in a non-uniform, donor-dependent manner. In the current study, platelet aggregation prof...
متن کاملTolerance to penicillin in streptococci of viridans group.
Tolerance to penicillin was investigated in 40 isolates of optochin-resistant, alpha-haemolytic streptococci. Thirteen strains exhibited tolerance to penicillin (MBC:MIC ratio greater than or equal to 32) when stationary phase inocula were used, but only seven strains retained the tolerance phenotype in experiments with logarithmic phase inocula. There was a striking association between toleran...
متن کاملIncidence of mefA and mefE genes in viridans group streptococci.
Viridans group streptococci form the major part of the commensal flora of the human upper respiratory tract. However, these organisms are also the leading cause of infective endocarditis and an increasing source of bacteremia in neutropenic patients (1). Beta-lactam agents are the treatment of choice for these infections, but macrolides and related drugs are recommended for prophylaxis and alte...
متن کاملSpecies-Specific Difference in Antimicrobial Susceptibility Among Viridans Group Streptococci
BACKGROUND Viridans group streptococci (VGS) are both commensal microbes and potential pathogens. Increasing resistance to penicillin in VGS is an ongoing issue in the clinical environment. We investigated the difference in susceptibility and resistance to penicillin among various VGS species. METHODS In total 1,448 VGS isolated from various clinical specimens were analyzed over a two-yr peri...
