Insights
Granulicatella adiacens, a rare Streptococcus variant, caused a parapharyngeal abscess in an infant. This case highlights a rare pediatric deep neck infection, successfully treated with antibiotics and drainage.
Area of Science:
- Microbiology
- Infectious Diseases
- Pediatrics
Background:
- Granulicatella adiacens is a bacterium rarely associated with pyogenic infections.
- While linked to endocarditis and bacteremia, its role in localized infections is less understood.
Observation:
- A 10-month-old infant presented with a parapharyngeal abscess.
- This deep neck infection (DNI) was caused by Granulicatella adiacens.
Findings:
- This represents the first reported pediatric deep soft tissue neck infection caused by G. adiacens.
- It is only the second reported localized infection by this bacterium in a pediatric patient.
Implications:
- This case expands the understanding of G. adiacens as a pathogen in pediatric deep neck infections.
- The report underscores the importance of considering rare bacteria in DNIs and includes a literature review for clinical guidance.
Abstract:
Granulicatella adiacens is a rare variant of the Streptococcus bacteria. When isolated, G. adiacens has been described in cases of endocarditis and bacteremia, but less commonly seen in isolated pyogenic infections. We report a case of a parapharyngeal abscess caused by G. adiacens in an otherwise healthy 10-month-old infant, which was successfully treated with antibiotics and surgical drainage. To the best of our knowledge, this is the first described case of a pediatric deep soft tissue neck infection caused by G. adiacens with one other report in an adult. Additionally, of all localized infections from this bacteria, this is only the second reported case in the pediatric population. We also include an evidence-based literature review of the clinical presentation, microbiology, imaging modalities, and management approach to deep neck infections (DNIs).

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
Acute Pyelonephritis II: Diagnostic Studies and Management
Tonsillitis II: Management
Acute Pyelonephritis I: Introduction
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
