EFFICACY OF A SUBUNIT APP VACCINE (PLEUROSTAR~(TM)4): A FIELD TRIAL IN THAILAND

摘要

Actinobacillus pleuropneumoniae (APP) is a causative agent of swine pleuropneumonia causing death losses, poor production, and increase costs of medication. APP-infected pigs may develop severe acute fibrinohemorrhagic pneumonia or chronic localized necrotizing pneumonia (1). In Thailand, serotypes 1, 2, 3, and 5 has been reported to cause pneumonic lesions in 5 different farms based on rapid plate agglutination and agar gel diffusion tests (2). Currently, it is possible to prevent infection by the use of vaccines.
