RESUMO
1. Monoclonal antibodies (MAbs) against surface antigens of Plasmodium gallinaceum sporozoites, an avian malaria parasite, were produced using spleen cells from mice immunized with sporozoites from mosquito salivary glands (SGS) or from midadgusts containing oocysts (OoS). 2. All of the 15 MAbs teted (11 anti-SGS and 4 anti-OoS) reacted with SGS and OoS by indirect immunofluorescence and circumsporozoiter precipitation reactions. Fourteen of these MAbs (11 anti-SGS and 3 anti-OoS) produced a Western blot (WB) patten identical to that produced with serum from mice lyperimmunized with viable intacts sporozoites. 3. All MAbs and the immune sera recognized only two polypeptide bands of approximate molecutlar weight 78 and 64KDa. 4. No difference in the WB pattern was observed when-or 12-day SGS or OoS extracts were used as antigens in WB. This antigenic similary was confirmed when the total protein extracts were visualized on silver-stained SDS-PAGE gel
