MICROBIOLOGY
- Fastidious, Gram-negative facultative anaerobic coccobacillus of Neisseriaceae family.
- Labs may misidentify due to organism tendency for crystal violet dye retention, therefore appearing Gram-positive.
- β-hemolytic, catalase negative; will not grow on MacConkey agar.
- Polysaccharide capsule aids in virulence and invasive abilities.
- Part of normal oral/respiratory and GU flora, especially in children.
- Colonization rates:
- 0-6 mos: 1%
- 12 mos- 4 yrs: 10-28%, toward higher-end especially in daycare population)
- Adults: 1%
- Colonization rates:
- Kingella kingae most frequent human pathogen.
- Other occasional species include K. dentrificans and K. oralis.
- Generally susceptible to many antibiotic classes.
- Intrinsically resistant to vancomycin and other glycopeptides; variable to clindamycin.
