The present invention relates to an ELISA diagnostic kit for the assay of A. pleuropneumoniae serotypes 5a and 5b antibodies in the serum of pigs comprising in separate packaging, at least one of the following: a) a plate or solid support having bound thereto a purified lipopolysaccharide A. pleuropneumoniae serotype 5 antigen for a specific binding to anti-A. pleuropneumoniae serotypes 5a or 5b antibodies present in the serum of pigs, wherein the bound antigen is stored in a solution which keeps said bound antigen stable for 25 weeks at 4°C: b) serum from pigs experimentally inoculated with a strain of A. pleuropneumoniae serotypes 5 to serve as a positive control; c) pig serum from A. pleuropneumoniae free herd to serve as a negative control; and d) a detectably labeled conjugate which bind to pigs antibodies bound to the plate of a).

Nécessaire de diagnostic ELISA pour le dosage des anticorps des sérotypes 5a et 5b de A. pleuropneumoniae dans le sérum de porcs, comprenant, sous emballage séparé, au moins l'un des éléments suivants: a) une plaque ou un support solide auquel est lié un antigène de sérotype 5 de A. pleuropneumoniae à lipopolysaccharide purifié se liant de façon spécifique aux anticorps de A. pleuropneumoniae de sérotypes 5a ou 5b présents dans le sérum porcs, l'antigène lié étant stocké dans une solution conservant cet antigène lié stable pendant 25 semaines à 4 DEG C; b) du sérum provenant de porcs auxquels a été inoculé expérimentalement une souche de sérotypes 5 de A. pleuropneumoniae pour le contrôle de fiabilité des résultats positifs; c) du sérum de porc provenant d'un troupeau non contaminé par A. pleuropneumoniae pour le contrôle de fiabilité des résultats négatifs; et d) un conjugué marqué de façon détectable qui se lie aux anticorps de porcs liés à la plaque de a).
