Document Summary
: microbial diseases of the cardiovascular and lymphatic system. Blood vessels: heart pumps blood into arteries that are connected to veins via capillaries. Arteries carry blood away from the heart. Endocarditis: involves inflammation of endocardium and heart valves, endocardium the inner layer of heart muscle, two types of endocarditis. Subacute bacterial endocarditis: the disease develops slowly, bacteria grow on preexisting lesions, if not treated, the disease is fatal within a few months, caused by a-hemolytic streptococci, the microorganisms enter the blood during the tooth extraction or tonsillectomy. Prophylactic antibiotic: staphylococcus aureus is transferred from original infection site to the heart (traumatic injury or surgical treatment. Acute bacterial endocarditis procedure: colonize heart valves (vegetations) cardiac malfunction, it causes a rapid destruction of heart valves, if untreated, can be fatal within a few days. Lyme disease: the causative agent is borrelia burgdorferi a spirochete, the infection has three phases:
