Endomyocardial fibrosis (Loeffler's endocarditis) is the main cause of poor outcome in Hyper Eosinophilic Syndrome (HES) and Eosinophilic Leukemia (EL). Reversion of the cardiac damage has been seldom reported, and thrombi can superimpose on infiltrated walls, originating oembolic complications. The
Treatment of infective endocarditis (IE) is a 4-6-week provided course of intravenously administered antibiotics. The aim of this study was to investigate how serum metabolites as measured by proton nuclear magnetic resonance (1H NMR) spectroscopy are changing over time during the active
Loefler endocarditis is a potential fatal adverse event of hypereosinophilic syndrome. We report a case of a 5-year-old girl diagnosed with peripheral hypereosinophilia refractory to corticosteroid therapy who developed eosinophilia-related endocarditis. Echocardiography revealed infiltration of the
A 53-year-old male presented with massive pruritus, whole-body exanthema, generalized muscle pain, and exercise dyspnoea NYHA II. Further hematologic examination lead to diagnosis of myeloid and lymphoid neoplasia with eosinophilia (MLN-EO) with We describe a patient with symptoms of heart failure caused by severe mitral regurgitation. Echocardiography revealed an intracardiac mass embedding the posterior mitral valve leaflet, and cardiac magnetic resonance imaging showed two intracardiac thrombi and endomyocardial fibrosis. Eosinophil
Streptococcus anginosus is frequently detected in patients with infective endocarditis, abscesses, or oral cancer. Although S. anginosus is considered the causative pathogen of these diseases, the pathogenic mechanisms of the bacterium have remained unclear. Previously, we suggested that an
BACKGROUND
Endocarditis-inducing streptococci form multilayered biofilms in complex with aggregated platelets on injured heart valves, but the host factors that interconnect and entrap these bacteria-platelet aggregates to promote vegetation formation were unclear.
RESULTS
In a Streptococcus mutans
A collection of 17 enterococci isolates obtained from fermentations of capers (the fruits of Capparis sp.) were investigated for incidence of known virulence determinants, antibiotic resistance and production of biogenic amines. Molecular identification revealed the presence of Enterococcus faecium
Total DNA extracted from Lb. plantarum ST8Sh was screened for the presence of more than 50 genes related to production of biogenic amines (histidine decarboxylase, tyrosine decarboxylase, and ornithine decarboxylase), virulence factors (sex pheromones, gelatinase, cytolysin, hyaluronidase,
OBJECTIVE
To better understand the mechanism of platelet recruitment and activation by Streptococcus gordonii. The oral bacterium Streptococcus gordonii, is amongst the most common pathogens isolated from infective endocarditis patients, and has the property of being able to activate platelets,
