Pediatric infective endocarditis (IE) can be serious, even in healthy children. Streptococcus mitis, identified via MALDI-TOF, caused IE in a child with a heart defect, highlighting the need for early diagnosis and potential surgery.
Area of Science:
- Cardiology
- Infectious Diseases
- Microbiology
Background:
- Infective endocarditis (IE) is rare in children, particularly those without congenital heart disease.
- Streptococcus mitis, an oral commensal, is an emerging cause of invasive IE due to adherence and biofilm formation.
- Accurate identification of S. mitis requires advanced techniques like MALDI-TOF MS due to its similarity to S. pneumoniae.
