Disease relevance of Viridans Streptococci

 

High impact information on Viridans Streptococci

  • Erythromycin-resistant Streptococcus viridans in oral flora with prolonged erythromycin therapy [6].
  • The conflicting observations could be explained by our finding that the reportedly serotype 4 zmpB 'mutant' differed from its S. pneumoniae parent in lacking capsule and in exhibiting characteristic traits of the Streptococcus viridans group, including resistance to optochin [7].
  • The glucosyltransferases (GTFs) of viridans streptococci, common pathogens of infective endocarditis, are extracellular proteins that convert sucrose into exopolysaccharides and glucans [8].
  • There is speculation of a possible association between exposure to antimalarial drugs and evolution of optochin resistance. alpha-Hemolytic streptococci resistant to optochin, particularly invasive isolates, should be tested for bile solubility or with an S. pneumoniae DNA probe before identification as viridans streptococci [9].
  • The characteristics of S. mutans and FBP-130 in binding Fn confirmed that viridans streptococci adopt different strategies in their interaction with ECM [10].

Gene context of Viridans Streptococci

  • Concentrations of IL-8, LBP and CRP were already significantly elevated before the onset of fever or bacteraemia due to oral viridans streptococci (OVS) in the first week after transplant during profound neutropenia [21].
  • The distribution of low (< or = 10(4)/ml) or high (> or = 10(5)/ml) concentrations of viridans streptococci did not differ substantially between asthma or COPD patients and control subjects [22].
  • Furthermore, in the presence of recombinant interferon-gamma, LTA from both strains of viridans streptococci provoked the accumulation of inducible nitric oxide (NO) synthase mRNA and the production of NO [23].
  • Multiple PBP targets may be modified by transformation and homologous recombination with DNA from PBP genes of viridans streptococci [24].
  • Identifications of viridans streptococci group or those that needed additional biochemicals for species identification occurred with 28% of isolates with the API 20S, 8% with the RapSTR, and 9% with the GPI card [25].
