beta-Hemolytic group F streptococcal bacteremia in children

Area of Science:

• Microbiology
• Pediatric Infectious Diseases
• Bacteriology

Background:

• Group F beta-hemolytic streptococci are known pathogens causing purulent disease and bacteremia primarily in adults.
• Infections attributed to these streptococci are considered uncommon in pediatric populations, particularly in previously healthy children.

Observation:

• This report details three distinct cases of group F beta-hemolytic streptococcal bacteremia.
• The cases involved previously healthy infants and children diagnosed over a decade at a single medical institution.
• Two of the three pediatric patients presented with concurrent meningitis, while the third experienced perforated appendicitis with peritonitis.

Findings:

• Group F beta-hemolytic streptococcal bacteremia, though rare, can occur in previously healthy pediatric patients.
• Severe complications such as meningitis and intra-abdominal sepsis (perforated appendicitis with peritonitis) can arise from these infections.
• These findings highlight the potential severity of group F streptococcal infections in children.

Implications:

• Clinicians should consider group F beta-hemolytic streptococci in the differential diagnosis of serious infections in previously healthy children.
• Early recognition and appropriate treatment are crucial to manage potential severe outcomes like meningitis and sepsis.
• Further research may be warranted to understand the epidemiology and pathogenesis of these infections in pediatric populations.
