Abstract:
Endocarditis due to Streptococcus gallolyticus, an agent previously included in the Streptococcus bovis denomination is a serious disease, often associated with lesions of the colon mucosa. Aortic valve is more often affected and tricuspid involvement is quite rare. We present a case of a 56-year-old man who was admitted with a 2-month history of fever. Echocardiogram revealed vegetations on the aortic and tricuspid valve and blood cultures grew S. gallolyticus. Thoracic X-ray and computed tomography were consistent with septic pulmonary embolism. Despite optimal antibiotic therapy he developed an ischemic stroke and acute aortic regurgitation, which led to emergent surgery. Colonoscopy found a benign adenoma which was excised, and the patient had a full recovery.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
