Clinical Effects

Epidemiology

Habitat

  • Mainly saprophytic.

Lifecycle

  • Multiply in soil, water and feces.
  • Can multiply in the host if normal flora have been disrupted.

Transmission

  • Environmental or endogenous exposure is constant.
  • Most infections are secondary to compromised host defenses.

Pathological effects

  • Capable of causing various diseases in wide range species.
  • Disease often due to production of toxins.
  • Cause of moist dermatitis in rabbits   Moist dermatitis  ; areas with excessive wetness most commonly affected.
  • Overweight rabbits and rabbits with large dewlaps most commonly affected.

Other Host Effects

  • Predisposing factors allow opportunist infection with pseudomonas, eg burns, reduction in normal flora following antibiotic treatment.

Control

Control via chemotherapies

  • Some species, egP. aeruginosahave multiple drug resistance.
  • Often susceptible to gentamicin   Gentamicin  , tobramycin, amikacin and carbenicillin for the treatment of soft tissue infections.
  • Tetracycline can achieve adequate concentrations in the canine urinary tract to kill most isolates.

Other countermeasures

  • Clip fur off from affected area.
  • Control underlying cause, eg dental disease causing excess salivation.
