Branhamella catarrhalis septic arthritis
The Journal of Rheumatology
|December 1, 1983
Summary
A rare case of spontaneous septic arthritis caused by Branhamella catarrhalis in an adult is presented. This bacterium, often resistant to penicillin, requires alternative antibiotic treatments like cephamycins or third-generation cephalosporins.
Area of Science:
- Microbiology
- Infectious Diseases
- Rheumatology
Background:
- Branhamella catarrhalis is a Gram-negative diplococcus, often found in the respiratory tract.
- While typically a commensal organism, it can cause various systemic infections.
Observation:
- A case of spontaneous septic arthritis in an adult patient caused by B. catarrhalis is detailed.
- This presentation highlights a less common, yet significant, manifestation of B. catarrhalis infection.
Findings:
- B. catarrhalis shares similarities with Neisseria species.
- The organism frequently exhibits resistance to penicillin antibiotics.
Implications:
- For B. catarrhalis infections, empiric antibiotic therapy should consider agents other than penicillin.
- Cephamycins or third-generation cephalosporins are recommended as potential first-line treatments due to resistance patterns.
