Enterococci are among the major pathogens implicated in cardiac infections and biofilm formation. E. faecalis has been shown to play an important role in infectious endocarditis. Several distinct mechanisms for biofilm formation have been identified in E. faecalis. Our group has previously characterized two distinct bacterial glucosyltransferases playing key roles in the production of the major...

Infective endocarditis is a common serious infectious pathology in children. The most commonly identified organisms are of the streptococcus and staphylococcus species. Patients always have a fever. Other signs of infective endocarditis include Roth spots, splinter hemorrhages, and Osler nodes. Blood cultures and echocardiography are very important in the establishment of the diagnosis. The dia...

We report a case of endocarditis due to a penicillin-"resistant" Streptococcus parasanguinis, discuss interpretations of the American Heart Association's guidelines for the treatment of viridans group streptococcal infection, and comment on therapy for infective endocarditis due to penicillin-resistant viridans group streptococci.

BACKGROUND Despite advances in antimicrobial and surgical therapy, septic arthritis remains a rheumatologic emergency that can lead to rapid joint destruction and irreversible loss of function. In adults, Staphylococcus aureus is the most common microorganism isolated from native joints. Streptococcus gordonii is a prominent member of the viridans group of oral bacteria and is among the bacteri...

Valvular stenosis is an uncommon finding in bacterial endocarditis involving native cardiac valves. Prosthetic valve endocarditis, however, is more commonly associated with obstruction. Bioprosthetic cardiac valves may be particularly prone to this complication. A case of bioprosthetic tricuspid valve endocarditis with stenosis diagnosed by Doppler echocardiography and confirmed by operative fi...

Infective endocarditis was a fatal disease three generations ago. Temporal evolution of knowledge made possible important advances in diagnostic techniques, especially in echocardiography, the possibility of cardiac surgery during the active infectious process and new guidelines for antibiotic prophylaxis before interventional procedures. Nowadays, infective endocarditis is curable. In this rev...

Invasive infections due to Pseudomonas stutzeri have rarely been described and mainly occur in immunocompromised individuals. We report a case of infective endocarditis caused by P. stutzeri after previous cardiac surgery in a Lebanese patient with Marfan syndrome. We review the literature and conclude that this pathogen may be of particular medical relevance in the Mediterranean Basin.
