- Small Gram negative coccobacilli
- Oxidase negative
- Do not grow on MacConkey
- Non-motile
- Facultative anaerobes which ferment carbohydrates to produce acid
Actinobacillus pleuropneumoniae
Actinobacillus seminis
- Epididymitis in young rams (4-8 months)
- Polyarthritis in lambs
- Organism found in prepuce
- Opportunistic infection causing abscesses in epididymides
- May be purulent discharge onto scrotal skin
- Specimens cultured on blood agar and incubated aerobically for 1-3 days produce pin-point haemolytic colonies which are catalase-positive; no growth on MacConkey agar
Actinobacillus actinomycetemcomitans
