Abstract:
Gemella haemolysans, a Gram positive cocci which are deemed to be the normal inhabitant of the mucous membranes of the oropharynx, has been recognized as a pathogen involved in abscess formation. The aim of this case report is to demonstrate that it is also involved in brain abscess in children. We report, to our knowledge, the first pediatric case of Gemella haemolysans brain abscess in an 11 years old child carrying a complex congenital heart disease (dextrocardia with single right ventricle) which evolved favorably under antibiotic therapy. Because of its similarity with Streptococcus viridans groupe, Gemella haemolysans often remains under-diagnosed in the laboratory. The contribution of microbiologists in its correct identification is very important.
Insights
Gemella haemolysans, a bacterium normally found in the throat, can cause brain abscesses in children, even those with congenital heart disease. Early diagnosis and antibiotic treatment are crucial for favorable outcomes.
Area of Science:
- Microbiology
- Pediatric Neurology
- Infectious Diseases
Background:
- Gemella haemolysans is a Gram-positive coccus typically residing in the oropharyngeal mucosa.
- While recognized for causing abscesses, its role in pediatric brain abscesses is less understood.
Observation:
- This case report details the first pediatric brain abscess caused by Gemella haemolysans in an 11-year-old child.
- The patient had a complex congenital heart condition (dextrocardia with a single right ventricle).
Findings:
- The pediatric patient with Gemella haemolysans brain abscess experienced a favorable outcome with antibiotic therapy.
- Gemella haemolysans can be misidentified due to its resemblance to Streptococcus viridans group.
Implications:
- This case highlights Gemella haemolysans as a potential pathogen in pediatric brain abscesses.
- Accurate laboratory identification of Gemella haemolysans is critical for appropriate patient management.
- Further research is needed to understand the full spectrum of Gemella haemolysans infections in children.
