- Fastidious Gram-negative facultative anaerobic bacillus
- Commensal flora of human mouth, thus is important pathogen in to consider with an infected human bite or "fight bites"
- Is one of the "HACEK" organisms that causes endocarditis
- May also cause bacteremia/endocarditis in insulin or IV drug users who lick their needles
- Typically causes indolent illness. Infected wounds can be extremely malodorous.
- Treat with penicillins, cephalosporins, or tetracyclines. It is resistant to macrolides, clindamycin, and metronidazole. Susceptible to fluoroquinolones in vitro. 
- S susceptible/sensitive (usually)
- I intermediate (variably susceptible/resistant)
- R resistant (or not effective clinically)
- S+ synergistic with cell wall antibiotics
- U sensitive for UTI only (non systemic infection)
- X1 no data
- X2 active in vitro, but not used clinically
- X3 active in vitro, but not clinically effective for Group A strep pharyngitis or infections due to E. faecalis
- X4 active in vitro, but not clinically effective for strep pneumonia
