Proportions of Streptococcus sanguis, an organism associated with subacute bacterial endocarditis, in human feces and dental plaque.
نویسندگان
چکیده
The relative absence of Streptococcus sanguis in human feces, in contrast to its high concentration on teeth, supports the concept of the mouth as the likely bacterial source in cases of subacute bacterial endocarditis involving this organism.

Effect of immunization on susceptibility to experimental Streptococcus mutans and Streptococcus sanguis endocarditis.
It has been asserted that humoral immunity is an important potentiating factor in pathogenesis of infective endocarditis, in that prior immunization to certain bacteria may predispose the host to endocarditis caused by those organisms. If so, possible future vaccination of humans with streptococcal antigens for the prevention of dental caries might increase the susceptibility of the population ...
متن کاملProphylactic Immunization against Streptococcus sanguis.
Streptococcus sanguis (the Streptococcus s.b.e. of Loewe), originally identified by White and his coworkers, has, with few exceptions, been isolated only from the blood stream of patients with subacute bacterial endocarditis (White, 1944; White and Niven, 1946; Niven and White, 1946; Loewe et al., 1946; Niven et al., 1946; Washburn et al., 1946). This causative organism has a type specificity a...
متن کاملEmergence of antibiotic resistant Streptococcus sanguis in dental plaque of children after frequent antibiotic therapy.
PURPOSE In the pediatric population, several different antibiotic regimens are currently recommended for the treatment of otitis media. This study investigated whether therapy for otitis media was associated with the emergence of antibiotic-resistant oral bacteria. METHODS Streptococcus sanguis (S. sanguis) was isolated from supragingival dental plaque of children after a recent course of ant...
متن کاملPhenotypic characterization of Streptococcus sanguis virulence factors associated with bacterial endocarditis.
Certain strains of Streptococcus sanguis adhere (Adh+) selectively to human platelets and, in plasma, induce them to aggregate (Agg+) into in vitro thrombi. In this study, we examined 18 recent endocarditis and dental plaque isolates of microorganisms that were biotyped as S. sanguis for coexpression of platelet interactivity phenotypes with another possible virulence factor in bacterial endoca...
متن کاملThe Streptococcus sanguinis Competence Regulon Is Not Required for Infective Endocarditis Virulence in a Rabbit Model
Streptococcus sanguinis is an important component of dental plaque and a leading cause of infective endocarditis. Genetic competence in S. sanguinis requires a quorum sensing system encoded by the early comCDE genes, as well as late genes controlled by the alternative sigma factor, ComX. Previous studies of Streptococcus pneumoniae and Streptococcus mutans have identified functions for the >100...
