- May be present in upper respiratory tract of sows
- Pathogenicity and clinical signs:
- Infection of piglets via aerosol or possibly skin abrasions
- Fatal septicaemia in piglets 1-8 weeks old
- Mortality up to 50% in some litters
- Fever, respiratory distress, prostration and paddling of forelimbs seen in piglets
- Petechial and ecchymotic haemorrhages in many organs
- Interstitial pneumonia, pleuritis, meningoencephalitis, myocarditis and arthritis
- Causes abscesses in joints and lungs of older pigs
- Carried in the nasopharynx of pigs and nose of horses
- Carriage may confer immunity to the more severe pleuropneumonia
- Diagnosis:
- Specimens cultured on blood agar and MacConkey agar for 1-3 days
- Sticky haemolytic colonies
- Pink, lactose-fermenting colonies on MacConkey agar
- Treatment and control:
- Bacteria usually susceptible to ampicillin, carbenicillin, potentiated sulphonamides and tetracyclines
- Disinfect contaminated pens
- Other animals:
- Septicaemia and pneumonia in foals
- Pneumonia in pigs and horses
