Abstract

Streptococcus agalactiae is a common bacteria known to cause meningitis and urinary tract infections in neonates and pregnant women, respectively. Recently, S. agalactiae has become an increasingly recognized pathogen in non-pregnant adults, manifesting most commonly as skin and soft tissue infections, urinary tract infections (UTIs), and pneumonia. Meningitis and endocarditis are among the most feared complications of S. agalactiae due to high morbidity and mortality, especially in adults over 65 years of age. Both of these complications are rare. We present a case of simultaneous S. agalactiae meningitis and endocarditis in a 69-year-old woman with a history of uncontrolled Type 2 diabetes mellitus. This case emphasizes the importance of prompt recognition and treatment of a complicated invasive S. agalactiae infection.
