Pleuropneumonia in pigs is spread rapidly by airborne routes or by direct contact, making factory farms an ideal breeding place. Considerable economic losses are seen due to mortality, growth retardation and the increased need for medication with antibiotics.
It is a highly contagious, often fatal, respiratory disease that is a major problem in most of Europe and the United States. The disease is caused by Actinobacillus pleuropneumoniae and causes depression, anorexia, high fever and laboured breathing. Blood stained froth may be seen at the mouth. It often kills 30-50 per cent of the pigs infected.
