**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

Overview

  • Organisms found in soil and water worldwide
  • Burkholderia mallei causes glanders; rodents act as reservoir of infection
  • Burkholderia pseudomallei causes meliodosis
  • Pseudomonas aeruginosa, found on skin, mucous membranes and in faeces, causes opportunistic infections

Characteristics

  • Gram-negative rods
  • Obligate aerobes
  • Oxidase and catalase positive
  • Pseudomonas species and Burkholderia pseudomallei motile by polar flagellae
  • Burkholderia mallei non-motile


Pseudomonas aeruginosa

Burkholderia mallei

Burkholderia pseudomallei
