SUBACUTE BACTERIAL ENDOCARDITIS CAUSED BY STREPTOCOCCUS SANGUIS

Subacute bacterial endocarditis caused by Cardiobacterium hominis: A case report

Cardiobacterium hominis, a member of the HACEK group of organisms, is an uncommon but important cause of subacute bacterial endocarditis. First-line therapy is a third-generation cephalosporin due to rare beta-lactamase production. The authors report a case involving endovascular infection due to C hominis that initially tested resistant to third-generation cephalosporins using an antibiotic gr...

Acute vertebral osteomyelitis complicating Streptococcus sanguis endocarditis.

The first well documented case of acute pyogenic vertebral osteomyelitis presenting as the initial manifestation of Streptococcus sanguis endocarditis is reported. The importance of suspecting vertebral osteomyelitis in the presence of disc infection and the diagnostic value of imaging procedures are underlined.

The role of fibronectin binding in the rat model of experimental endocarditis caused by Streptococcus sanguis.

Inactivation of fibronectin (Fn) binding by insertional mutagenesis of Streptococcus sanguis with Tn916 reduces virulence of this bacterium in the rat model of infective endocarditis (IE). Transconjugants were screened for Fn adherence using an ELISA adherence test. One transconjugant had a decreased adherence to immobilized Fn. Southern hybridization demonstrated that the insertion occurred on...

Proportions of Streptococcus sanguis, an organism associated with subacute bacterial endocarditis, in human feces and dental plaque.

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.
