Habitat

  • Thrives in wet, poorly aerated environments in vet hospital such as anesthetic hoses or disinfectant solutions.
  • Mainly saprophytic.
  • Human and animal gastrointestinal tract, water, soil and sewage.
  • Ubiquitous in environment.

Lifecycle

  • Multiplies in environment by binary fission.
  • Non-spore-forming.

Pathological effects

  • Capable of causing various diseases in wide range species.
  • Disease often due to production of toxins.

Other Host Effects

Control

Control via chemotherapies

  • Some species, eg P. aeruginosa have multiple drug resistance.
  • Strains may be resistant to all systemic antibiotics routinely tested.
  • Usually susceptible to gentamycin, tobramycin, amikacin and carbenicillin for treatment of soft tissue infections.
  • Tetracycline reaches bactericidal concentrations against P. aeruginosa in urine.
  • Most pseudomonads are susceptible to levels of antimicrobial agents in otic preparations, including neomycin, polymysin, chloramphenicol and gentamycin.
