Summary
This case report details a rare instance of Serratia rubidaea sepsis in a patient with a history of pancreatitis and diabetes. Prompt antibiotic treatment led to recovery, highlighting the importance of recognizing less common Serratia infections.
Area of Science:
- Infectious Diseases
- Microbiology
- Internal Medicine
Background:
- Patient presented with a history of alcoholic pancreatitis and diabetes mellitus.
- Admitted with symptoms including chills, vomiting, altered consciousness, tachypnea, and tachycardia.
Observation:
- Physical examination revealed fever (38.0°C), hepatomegaly with tenderness.
- Laboratory findings indicated severe inflammatory response, disseminated intravascular coagulation (DIC), and hepatorenal dysfunction.
Findings:
- Abdominal CT and US identified multiple liver abscesses and portal vein thrombus.
- Blood cultures isolated Serratia rubidaea, confirming sepsis.
- Treatment with Sulbactam/Cefoperazone (SBT/CPZ) and Tobramycin (TOB) resulted in patient recovery.
Implications:
- This case underscores the rarity of Serratia rubidaea sepsis.
- Highlights the need for vigilance regarding Serratia species infections beyond the more commonly implicated S. marcescens.
- Emphasizes prompt diagnosis and appropriate antimicrobial therapy for severe bacterial infections.
