Revision as of 18:01, 27 September 2023
Background
Microbiology
- A non-motile Gram-negative bacillus (rather than coccus) within the genus Neisseria
- Catalase-negative and superoxol-negative
- Part of the normal oropharyngeal flora
Clinical Manifestations
- Most case reports describe endocarditis, though it is rare[1]
- High rates of perivalvular abscess and valvular perforation
- Mostly in young men with underlying valvular abnormalities
- May be precipitated by dental work
- Even more rarely, osteomyelitis[2]
Management
- Usually susceptible to amoxicillin, gentamicin, and ciprofloxacin
- May have reduced susceptibility to ceftriaxone
