*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
