- Grows best on blood agar medium or chocolate medium (blood heated at 176-194o F, Fig 1).
- Has a loose capsule and pili. Antigenic variation of pili can be used for epidemiological characterization.
- Strains with nutrient requirements for arginine, hypoxanthine or uracil are more likely to cause asymptomatic infection.
- Grows best on blood agar medium or chocolate medium (blood heated at 176-194o F, Fig 1).
