- Pathogen:
- Actinobacillus spp.
- Precautions:
- Standard
- Diagnosis:
- On blood agar, A. lignieresii, A. equuli and A. suis exhibit cohesive properties when touched. A. equuli and A. suis produce pink colonies on MacConkey agar. A. pleuropneumoniae and A. seminis do not grow on MacConkey agar.
- Pathogen Information:
- Non-motile, gram-negative rods that sometimes appear as coccobacilli.
- Epidemiology:
- Typically host specific. Commensals on mucous membranes. Some species are non-pathogenic and virulence may differ between serotypes within species. Carrier animals play a large role in transmission.
- Associated Syndromes:
- Actinobacillosis, Pleuropneumonia, Septicemia enteritis, Pneumonia, Epididymitis, Polyarthritis.
