The possibility to use serological examination to diagnose accute pleuropneumonia in pigs was investigated in a farm with 1,000 sows (all in all out system) and Actinobacillus pleuropneumoniae (serotype 9) occurrence. Enzymatic immunoanalysis was used to follow the evolution of antibody concentration in blood sera of non-vaccinated piglets and piglets vaccinated by the commercial vaccine Suivac APP. As the colostral immunity decreased between the nineth and tenth weeks, piglets were vaccinated the sixth and the eighth weeks. The vaccination decreased clinical symptoms of pleuropneumonia, mortality and economic losses. The antibody concentrations were higher in non-vaccinated piglets than in the vaccinated ones.
