Recurrent erysipelas caused by group B streptococcus organisms.

Area of Science:

• Infectious Diseases
• Bacteriology
• Clinical Medicine

Background:

• Group B beta-hemolytic streptococcus (GBS) is a significant pathogen, primarily known for neonatal infections.
• Serious GBS infections in adults are often associated with predisposing medical conditions.
• Chronic lymphedema can increase susceptibility to infections.

Observation:

• A case of recurrent erysipelas in a woman with chronic lymphedema post-hysterectomy and radiation therapy is presented.
• Type III GBS was isolated from multiple sites, including vulvar vesicles, vaginal mucosa, and blood.
• Erysipelas is a bacterial skin infection that can lead to serious complications.

Findings:

• The identification of Type III GBS in a recurrent erysipelas case highlights its potential in adult infections.
• Prophylactic penicillin V potassium therapy proved effective in preventing subsequent erysipelas episodes.
• This case demonstrates the efficacy of targeted antibiotic prophylaxis in managing recurrent GBS infections.

Implications:

• Group B beta-hemolytic streptococcus should be considered in the differential diagnosis of adult erysipelas and cellulitis.
• Understanding GBS in adults with compromised lymphatic systems is crucial for effective treatment.
• Prophylactic antibiotic strategies may be beneficial for individuals at high risk of recurrent GBS infections.
