Inquilinus limosus

  • General information

    • the following information is not yet verified
      Patients with cystic fibrosis (CF) may be colonized with unusual gram-negative bacilli whose identification is difficult and clinical impact unclear.

      Family: Rhodospirillaceae

      I.limosus belongs to the α-proteobacteria (class), and is therefore not closely related to B.cepacia complex or P. aeruginosa

      Natural habitat
      The natural reservoir is yet to be discovered, but its relationship with other non-fermentative rods suggests ecological resources

      Clinical significance
      I. limosus is able to stay for several months in the respiratory tract of CF-patients

      Just as with the P.aeruginosa is an abundant production of mucus from I.limosus favorable for a persistent chronic infection.

      However, the pathogenic role of I.limosus is unclear.

    • the following information is not yet verified

      Obligate Aerobic

      The strain grows slowly, 1st isolate after 3-5 days, can therefore be missed.

      The colonies are very mucoid and milky white and not pigmented

      McConkey they grow poorly or not at all
