This article explains the main preventive measures against App, focusing on the use of antimicrobials and vaccines.
Practical experiences in swine disease control
This article is about the diagnosis of the infection caused by Actinobacillus pleuropneumoniae (App) in acute, chronic or subclinical cases.
Diarrhoea is their most typical clinical manifestation, and the earlier the onset, the more harmful it is. Newborn piglets can present with another clinical picture, with signs of sepsis (shock, depression, death, polyarthritis), which is associated with an extraintestinal E. coli.
Management factors and environmental conditions are often triggers or predisposing agents, not only to the clinical presentation of the disease, but also its severity and course.
It has not proved possible to actively eliminate App from chronically affected permanently occupied breeder-feeder herds.
This paper describes the acute outbreak of App within a pig population and how control may be achieved.
Gilts are the population most likely to excrete M. hyo during lactation because they will probably have become infected within 200 days prior to their first farrowing.
