The major challenge in diagnosing infective endocarditis using fluorine-fluorodeoxyglucose (F-FDG) PET/computed tomography (CT) is the high physiological myocardial F-FDG uptake, which may interfere with the detection of pathological uptake. Our aim was to retrospectively analyse the A collection of Streptococcus sanguinis strains from patients with endocarditis (n = 21) and from the oral cavity (n = 34) was subjected to a multi-locus sequence typing analysis using seven housekeeping genes, carbamoyl-phosphate synthetase (carB), Co/Zn/Cd efflux system component (czcD),
We report a case of multiple embolic cerebral infarcts associated with nonbacterial thrombotic endocarditis (NBTE) in a patient with adenomyosis. The patient presented with dysarthria, left perioral sensory change, and left-hand weakness. Magnetic resonance imaging revealed multiple vascular
The objectives of this work were to compare the infrared spectra of bacterial endocarditis vegetation with those of native valvular tissue and the infrared spectra of vegetation bacterial masses with those of surrounding vegetation tissue. Streptococcal aortic endocarditis was induced in three
Enterococcus faecium is a common cause of nosocomial infections, of which infective endocarditis is associated with substantial mortality. In this study, we used a microarray-based transposon mapping (M-TraM) approach to evaluate a rat endocarditis model and identified a gene, originally annotated
CDC group M-6 is the vernacular name given to a gram-negative, oxidase-positive, aerobic, nonmotile, rod-shaped bacterium. This organism is biochemically similar to Kingella denitrificans and displays a cellular fatty acid profile consistent with CDC groups M-5 and EF-4 and with Neisseria elongata.
GspB is a serine-rich repeat (SRR) adhesin of Streptococcus gordonii that mediates binding of this organism to human platelets via its interaction with sialyl-T antigen on the receptor GPIbα. This interaction appears to be a major virulence determinant in the pathogenesis of infective endocarditis.
A case of subacute bacterial endocarditis in which Cardiobacterium hominis was isolated from the blood of a 55-year old woman who had rheumatic heart disease is reported. A survey of the literature revealed very few reports in which this organism has been implicated in human lesions. The colonies
We report a case of a 48-year-old woman with multiple cerebral infarctions caused by nonbacterial thrombotic endocarditis (NBTE) because of adenomyosis with high serum carbohydrate antigen (CA)125 level. Transesophageal echocardiography (TEE) showed a vegetation, 4 mm in diameter, adjacent to the
Two cases of endocarditis caused by Cardiobacterium hominis are reported. There were no unusual clinical features of endocarditis in the patients except for the extensive valvular damage present at time of hospitalization. Properties with distinguish C. hominis from other fastidious, gram negative
BACKGROUND
Diabetes mellitus is a frequent underlying comorbidity in patients with Staphylococcus aureus endocarditis, and it represents a risk factor for complications and a negative outcome. The pathogenesis of staphylococcal endocardial infections in diabetic hosts has been poorly characterized,
Adherence to host surfaces is often mediated by bacterial binding to surface carbohydrates. Although it is widely appreciated that some bacterial species express glycosidases, previous studies have not considered whether bacteria bind to multiple carbohydrates within host glycans as they are
OBJECTIVE
Early detection of infectious endocarditis is challenging. For diagnosing infectious endocarditis, the revised Duke criteria are the gold standard. Evidence of endocardial involvement on echocardiography is a major criterion, but sensitivity and specificity of echocardiography are not
Streptococcus gallolyticus (formerly known as Streptococcus bovis biotype I) is an increasing cause of endocarditis among streptococci and frequently associated with colon cancer. S. gallolyticus is part of the rumen flora but also a cause of disease in ruminants as well as in birds. Here we report
