Porcine pleuropneumonia caused by the lung-infectious
pathogen Actinobacillus pleuropneumoniae affects pigs of all
ages worldwide, and is responsible for serious losses in the
swine industry. The peracute formof the infection leads to a
high mortality, and the chronic form to persistent lung
lesions. Apart from vaccines, antibiotics are applied to
control the disease. However, increasing concerns about the
use of antibiotics call for alternative approaches.
