Abstract:
Small colony variant Staphylococcus aureus colonies are identified in persistent or relapsing S. aureus infections after prolonged antibiotic therapy. An unusual case of multiorgan infection in the absence of prolonged antibiotic therapy in a pediatric patient is reported.
Insights
Small colony variant Staphylococcus aureus causes persistent infections, often after antibiotic use. This report details a rare pediatric case of multiorgan infection without prior prolonged antibiotic treatment.
Area of Science:
- Microbiology
- Infectious Diseases
- Pediatrics
Background:
- Small colony variants (SCVs) of Staphylococcus aureus are associated with persistent and relapsing infections.
- SCVs are typically identified following prolonged antibiotic therapy, complicating treatment outcomes.
Observation:
- An unusual case of multiorgan infection involving Staphylococcus aureus SCVs in a pediatric patient is presented.
- This case occurred in the absence of a history of prolonged antibiotic therapy.
Findings:
- The study reports a rare presentation of Staphylococcus aureus SCV infection in a pediatric patient.
- Multiorgan involvement was observed despite the lack of prolonged antibiotic exposure, challenging typical clinical presentations.
Implications:
- This case highlights the potential for SCV Staphylococcus aureus to cause severe infections in pediatric patients even without prior antibiotic exposure.
- Understanding atypical presentations of SCV infections is crucial for timely diagnosis and effective management in pediatric populations.
- Further research may be needed to elucidate the mechanisms driving SCV formation and virulence in diverse clinical scenarios.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
