      K. rosea found in environmental sources and human skin.
      It is considered part of the normal skin flora, but it can be an opportunistic pathogen.

      It is generally sensitive to many antibiotics, though antibiotic resistance can occur.

  • Gram stain

    • Gram positive cocci,

      0.5-3.5 µm,

      occurring mostly tetrads, and irregular clusters.

      Mature cells lose the ability to retain the crystal violet, which makes them decolorization easier than younger cells.

  • Culture characteristics

    • Obligate aerobic

      BA: after 48 hours the colonies are 1-2 mm in diameter (grow more slowly than staphylococci).

      Colonies dull or matte, convex and have a pink to orange-red pigment..
