Gordonia sputi

  • General information


    • Taxonomy
      Family: Gordoniaceae

      Natural habitats
      In the environment, soil, marine sediments and wastewater systems.

      Infection is primarily by inhalation of the bacteria.

      Clinical significance
      Are rarely found in humans. Pathogenicity is unknown.

      This organism is known to cause infections in immunocompromised and immunocompetent hosts.
      It can cause, skin infections, chronic pulmonary disease, catheter-related sepsis, wound infections and septicemia.

  • Gram stain

    • Gram positive rods,

      0.5-1.0 x 1.0-2.5 µm,

      short rods and cocci, which resemble thin beaded coccobacilli.

      They occur singly, in pairs, in V-shaped arrangements, or as short chains.

      Rod-coccus life cycle.
      Cells in early growth phase are rods and those in exponential phase are cocci.

      Elementary branched hyphae which fragments into rod- and coccoid-like elements are formed by some species.

      They stain Gram positive or Gram variable

      Could easily be mistaken for a component of the normal oral biota in sputum specimens

      modified Kinyoun partially acid fast

  • Culture characteristics

    • Obligate aerobic

      BA: after 2-5 days colonies are rough, wrinkled, beige, brownish, salmon to pink or orange to red, particularly on chocolate agar

      Cultures showing smooth colonies can generate rough colonies, a change which seems to be irreversible.

      Aerial hyphae negative

      BBAØ: no growth
