Wound infection associated with Vibrio alginolyticus

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Medicine

Background:

• Vibrio species are halophilic bacteria commonly found in marine environments.
• Certain Vibrio species can cause human infections, particularly wound infections in individuals with compromised skin integrity.
• Understanding the characteristics of different Vibrio species is crucial for accurate diagnosis and treatment.

Observation:

• A 42-year-old male presented with an infected, ulcerated lesion on his right lower extremity.
• Vibrio alginolyticus was repeatedly isolated from the wound exudate.
• The clinical presentation and laboratory findings were consistent with a Vibrio infection.

Findings:

• The isolated organism was identified as Vibrio alginolyticus based on its biochemical and cultural characteristics.
• The study emphasizes the importance of recognizing the clinical manifestations of Vibrio alginolyticus wound infections.
• Key laboratory features aiding in the differentiation of Vibrio alginolyticus from other halophilic vibrios were highlighted.

Implications:

• This case underscores the potential for Vibrio alginolyticus to cause significant soft tissue infections.
• Accurate identification and differentiation from related Vibrio species are essential for appropriate patient management.
• Clinicians should consider Vibrio infections in patients with exposure to marine environments presenting with wound complications.
