Granulicatella adiacens abscess: Two rare cases and review

Area of Science:

• Microbiology
• Infectious Diseases

Background:

• Granulicatella adiacens is a nutritionally variant streptococcus species known for fastidious growth requirements.
• This bacterium is typically associated with bloodstream infections, infective endocarditis, and localized infections of the orbit, nasolacrimal duct, and breast implants.

Observation:

• This report presents two cases of subcutaneous abscesses caused by G. adiacens.
• The first case involved an abscess around the elbow joint, and the second case was a suprapatellar abscess.

Findings:

• The study highlights the rare occurrence of G. adiacens in subcutaneous infections.
• A review of published data on the diagnosis and antimicrobial susceptibility patterns of Granulicatella infections, including Indian cases, is provided.

Implications:

• These findings expand the known clinical spectrum of G. adiacens infections.
• Understanding the diagnostic challenges and antimicrobial susceptibility is crucial for effective management of G. adiacens-related infections.
