**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
