RESUMO

Kinetics of the humoral immune primary response and seven-day secondary response of adult CF1 mice to FMDV O1 Campos adjuvanted in aluminium hydroxide-saponin (AHS) or in oil emulsion (OE) were evaluated by means of ELISA and passive hemagglutination (PH). Analysis of the response to AHS vaccine showed that ELISA measured maximal titres of primary response at 23 days post-vaccination (dpv), and at day 17 of secondary response, while PH detected maximal titres for primary as well as secondary response around day 60 pv. Mice immunized with OE vaccine studied by ELISA presented a plateau of primary response around 40 dpv, while secondary response was maximal around 80 dpv. The same sera tested by PH showed the highest titres for primary response on day 50 pv and secondary response was maximal on day 40 pv. A criterion for the evaluation of vaccination efficiency in the murine model is proposed based on the methods employed in the determination of antibody level.

RESUMO

Un hexadecapéptido correspondiente a la secuencia 144-159 de la proteína estructural VP1 del virus de la fiebre aftosa (CFA), cepa O1K, fue sintetizado por métodos químicos. El mismo, acoplado covalentemente a distintas proteínas portadoras, demostró su capacidad de inducir anticuerpos neutralizantes del VFA cepa O1 Campos (O1Ca) en ratones adultos. La protección fue del 100% cuando se lo acopló a la hemocianina de un molusco (KLH) y fue inoculado en cantidad de 60 microng, dividida en dos dosis y adyuvada con mezcla oleosa. Las proteínas utilizadas como portadoras: albúmina bovina, purificado proteico de Mycobacterium (PPD), gliadina y células de Brocelas produjeron una respuesta inmune menor que la KLH
