*Causes [[Respiratory Bacterial Infections - Pathology#Melioidosis (Pseudoglanders)|melioidosis]] - endemic in Asia and Australia
  −
*Primarily infects rodents
  −
*Pathogenesis:
  −
**Infection via ingestion, inhalation or skin wounds from environment
  −
**Exotoxin, dermonecrotic protease and lecithinase implicated in pathogenicity
  −
**Strain virulence and host immunosuppression important
  −
*Clinical infections:
  −
**Opportunistic infection with stress and immunosuppression predisposing to disease
  −
**Abscesses develop in many organs including lungs, spleen, liver, joints, CNS, upper respiratory tract
  −
**Chronic, debilitating, progressive disease with long incubation period
  −
**Many animal species susceptible
  −
**Referred to as pseudoglanders in horses
  −
*Diagnosis:
  −
**Specimens: pus from abscesses, affected tissues, blood
  −
**Fluorescent antibody technique on tissue smears
  −
**Blood agar and MacConkey agar plates, incubated aerobically
  −
**Colonies have musty smell
  −
**Lactose fermentation on MacConkey
  −
**Slide agglutination
  −
**ELISA, complement fixation and indirect haemagglutination tests for serum antibodies
  −
*Treatment/control: slaughter of infected animals where exotic
