Invasive Group B Streptococcal Infection with Toxic Shock-Like Syndrome in a Postsplenectomy Patient

Streptococcus agalactiae Infective Endocarditis in a Young Immunocompetent Male

Group B Streptococcus endocarditis is a rare but serious condition, characterized by the infection of heart valves and associated with a high mortality rate. The emergence of antibiotic-resistant strains adds complexity to therapeutic strategies, emphasizing the importance of tailored antibiotic regimens and surgical interventions when indicated. Early diagnosis and multidisciplinary care are essential in improving patient outcomes. A 22-year-old male patient with no comorbidities was admitted with a thromboembolic stroke. MRI brain showed bilateral cerebral and cerebellar multifocal acute nonhemorrhagic infarcts. He was found to have Streptococcus agalactiae bacteremia, and infective mitral valve endocarditis. He underwent mitral valve replacement and IV antibiotic treatment with a successful outcome.
