    Abstract Endocarditis is an infectious disease, caused in most cases by bacteria from other parts of the body or introduced into the body during medical maneuvers, being called infective endocarditis IE.

    Although it is an uncommon disease, IE is among the first life-threatening infections. Damaged or artificial heart valves, congenital or other heart defects and increasing percentage of cardiac devices represent various risk factors, most often flaged for developing this disease.

    Among the etiologic agents, Staphylococcus aureus is the pathogen most frequently isolated in bacterial endocarditis. Other pathogens isolated from cases of IE are coagulase-negative staphylococci, beta-hemolytic streptococci, gram-negative group HACEK, Pseudomonas aeruginosa, Corynebacterium spp. IE types are described according to various causes and their causative agents: the native valve IE, prosthetic valve IE artificialIE by intravenous administration of illegal drugs through the use of cardiac devices, nosocomial IE.

    Penetration of the pathogen into the bloodstream bacteremiafollowed by adherence at the level of damaged areas in parietal endocardial, the heart valves, subvalvular apparatus or a blood vessel, forming lesions vegetating and ulcerative necrotic, represent the steps in a complex process in IE development.

    Food poisoning caused by microorganisms signs and symptoms of IE are fever, chills, weight loss, heart murmur, vascular and immunological phenomena as well. Diagnosis is based on clinical manifestations, laboratory investigations, imaging techniques and microbiological investigations, most of them being the base of the modified Dukes criteria to facilitate the diagnosis of this disease.

    Treatment of IE requires eradication of the infection and the treatment of complications, which involves antibiotics and surgery to remove infected material and draining abscesses. Also, prevention measures are an important chapter in the management of infective endocarditis.
