Yersinia enterocolitica lung infection

Area of Science:

• Infectious Diseases
• Pulmonology
• Microbiology

Background:

• Yersinia enterocolitica is a bacterium typically associated with gastrointestinal illness.
• Pulmonary manifestations of Yersinia enterocolitica are rare, especially in adults without septicemia or acute GI symptoms.

Observation:

• A 66-year-old male presented with pneumonia, lung abscesses, and mediastinal adenopathy.
• The patient had no signs of septicemia or acute gastrointestinal disease.
• Diagnosis was confirmed via transtracheal aspirate and sputum cultures identifying Yersinia enterocolitica.

Findings:

• This case highlights a rare presentation of Yersinia enterocolitica in the lungs.
• Cultures confirmed the causative agent as Yersinia enterocolitica.
• Successful treatment was achieved with cefamandole nafate, an antibiotic not previously documented for this specific condition.

Implications:

• This case expands the known spectrum of Yersinia enterocolitica infections.
• It suggests cefamandole nafate as a potential therapeutic option for Yersinia enterocolitica-induced lung disease.
• Further research into non-gastrointestinal Yersinia enterocolitica infections is warranted.
