Abstract

Streptococcus suis (S. suis) can cause various types of infection, leading to high mortality and morbidity rate. However, it is an uncommon pathogen of elderly population infection. Herein, we report a case of 85-year-old female who diagnosed as infective endocarditis caused by S. suis, which is the first reported case of infective endocarditis caused by S. suis in Taiwan, underscoring the critical role of echocardiography in patients presenting with S. suis bacteremia. This patient received antibiotics therapy and was discharged uneventfully after completed treatment courses. Early diagnosis and prompt initiation of appropriate antibiotic therapy are essential in managing such cases.
