Actinobacillus pleuropneumoniae is the causative agent of porcine pleuropneumonia, an economically important endemic bacterial disease of pigs worldwide (Bossé and others 2002). Epidemiologically, serotyping is the gold standard method, with A pleuropneumoniae being classified into 16 different serovars (1 to 4, 5a, 5b, 6 to 15) based on the presence of surface carbohydrates, principally of the capsule. The prevalence of different serovars varies from country to country (Dubreuil and others 2000). Classically, the serovar of an isolate is determined immunologically using polyclonal serum obtained from animals (typically rabbits) that have been immunised with killed whole cells of a reference strain of the relevant serovar. Such immunological-based methods have limitations, in particular, crossreactivity between serovars. Cross-reactivity has been reported between serovars 1, 9 and 11,
