Summary
This study details the first reported case of Gordonibacter pamelaeae bacteremia in a patient with advanced rectosigmoid carcinoma. The infection responded well to amoxicillin-clavulanate treatment.
Area of Science:
- Microbiology
- Clinical Medicine
- Genetics
Background:
- Disseminated rectosigmoid carcinoma presents complex clinical challenges.
- Bacteremia can complicate cancer treatment and patient outcomes.
- Identifying causative agents is crucial for effective antimicrobial therapy.
Observation:
- A patient with disseminated rectosigmoid carcinoma developed bacteremia.
- The causative agent was identified as Gordonibacter pamelaeae.
- Phenotypic tests and 16S rRNA sequencing confirmed the bacterium's identity.
Findings:
- Gordonibacter pamelaeae is a nonsporulating, anaerobic, gram-positive coccobacillus.
- The bacterium tested positive for catalase, arginine dihydrolase, and arginine acrylamidase.
- The gastrointestinal tract is the likely reservoir for this bacterium.
Implications:
- This is the first documented case of Gordonibacter pamelaeae bacteremia.
- Amoxicillin-clavulanate demonstrated efficacy in treating this infection.
- Understanding the reservoir may inform future diagnostic and preventative strategies.
