Phylogenetic analysis of viridans group streptococci causing endocarditis.
Identification of viridans group streptococci (VGS) to the species level is difficult because VGS exchange genetic material. We performed multilocus DNA target sequencing to assess phylogenetic concordance of VGS for a well-defined clinical syndrome. The hierarchy of sequence data was often discordant, underscoring the importance of establishing biological relevance for finer phylogenetic disti...
متن کاملMannosidase 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 کاملDiscrimination of Streptococcus pneumoniae from viridans group streptococci by genomic subtractive hybridization.
Two oligonucleotide primer sets for the discrimination of Streptococcus pneumoniae from "pneumococcus-like" oral streptococcal isolates by PCR were developed. Genomic subtractive hybridization was performed to search for differences between Streptococcus pneumoniae strain WU2 and the most closely related oral streptococcus, Streptococcus mitis strain 903. We identified 19 clones that contained ...
متن کاملAntibiotic sensitivities of Streptococcus pneumoniae, viridans streptococci, and group A hemolytic streptococci isolated from the maxillary and ethmoid sinuses.
OBJECTIVES To investigate antibiotic sensitivities of Streptococcus pneumoniae, viridans streptococci, and group A hemolytic streptococci isolated from the culture materials obtained from the sinuses of patients undergoing functional endoscopic sinus surgery due to chronic sinusitis. PATIENTS AND METHODS We recruited 93 patients (63 males, 30 females; mean age 36+/-17.5; range 19 to 68 years)...
متن کاملAn immunofluorescent method for detecting antibodies against viridans streptococci in Streptococcus viridans endocarditis.
Serum was collected one to three months after the onset of symptoms from eight endocarditis cases and from another endocarditis case about three weeks after the onset of symptoms (case 8 in Table). Endocarditis was proven in each case clinically and by numerous sets of blood -cultures that yielded growth of viridans streptococci. Three positive standard reference sera, obtained from patients wi...
