Corynebacterium mucifaciens

  • General information

    • the following information is not yet verified
      The pathogenic potential of coryneform bacteria has been underestimated

      Family: Corynebacteriaceae

      Natural habitats
      Part of the normal flora of skin, their potential pathogenicity still remains to be assessed.

      They has been mainly isolated from skin, blood and from normally sterile body fluids

      Clinical significance
      C. mucifaciens should be considered as important human pathogen in patients with severe illness and compatible history of exposure even in individuals with no clearly identified immunosuppression

      Corynebacterium species are becoming recognized as an increasing cause of opportunistic infections.

  • Gram stain

    • the following information is not yet verified
      Gram positive rods,

      irregularly shaped (‘coryneforms”), they are arranged as single cells, in pairs, in V forms, in palisades, or in clusters with

      a so-called Chinese-letter appearance.

      Club-shaped rods are observed in true members of the genus Corynebacterium only

  • Culture characteristics

    • the following information is not yet verified

      Obligate aerobic
      Colonies are very distict because they are slightly to overtly yellow and very mucoid.
      (very few strains are not mucoid)
      Colonies are about 1 to 1.5 mm after 24h of incubation and have entire edges.
      They appear less mucoid after extended incubation for 96h.

      C. mucifaciens exhibiting such mucoid colonies, this characteristic strongly reminds bacteriologists of Rhodococcus equi colonies.
