| Popis: | The specific identification of plasmodial sporozoites is not possible on morphological grounds. This study presents a serological method for the identification of sporozoite species, indicating the suitability of this approach for detection and determination of sporozoites in wild vectors collected from malaria endemic areas. Specific antisera and monoclonal antibodies prepared against each of two species of rodent malaria (Plasmodium berghei or P. yoelii) were evaluated for their ability to discriminate among sporozoites of different malaria species (P. vivax, P. gallinaceum, P. berghei, P. yoelii) from varied host types. Antisera produced by intravenous immunization of rabbits or mice and hybridoma-produced monoclonal antibodies reacted only with homologous sporozoites in an immunofluorescent antibody test. Antisera produced by intravenous challenge showed no significant difference in reactivity with fresh sporozoites as compared with sporozoites frozen at −80 °C for up to six months, whereas antisera produced by infective mosquito bites showed reduced sensitivity to frozen-stored homologous sporozoites and some cross-reactions with heterologous sporozoites. Antisera prepared against the erythrocytic stages of P. berghei or P. yoelii also cross-reacted with sporozoites of all four plasmodia tested, indicating that it is advantageous to use anti-sporozoite antibodies for the identification of malaria sporozoite species by means of serological tests. |
