| Serum samples collected from 358 wild boars (Sus scrofa) in breeding farms in São Paulo, southeast Brazil, from 1998 to 2001, were tested for antibodies against pseudorabies virus (PRV) by means of serum neutralization (SN) and enzyme-linked immunobsorbent assay (ELISA). Seropositive animals were detected in three of seven herds analyzed. Overall seroprevalence as assessed by SN was 30.7%, ranging from 25.2% to 100% for the herds that presented seropositive animals. Indirect ELISA detected lower seroprevalence (19.3%). Sensitivity and specificity of ELISA were equal to 57.3% and 97.6%, respectively. Agreement was equal to 85.2% (P<0.0001). These results showed that PRV infections occurred in farmed feral swine in southeast Brazil, and affect... |

| To develop a vaccine against cryptosporidiosis in animals, we constructed recombinant pseudorabies virus (PrV), a member of the Herpesviridae Alphaherpesvirus subfamily, expressing an immunodominant surface protein p23 of Cryptosporidium parvum sporozoites. Because of the wide host range of PrV, it has the possibility as the vector to delivery the foreign genes to several species of animals containing experiment animal. In the recombinant constructed in this study, the p23 gene under the control of CAG promoter was integrated into the thymidine kinase (TK) gene of PRV. Antibody against p23 recognized p23 expressed in CPK cells infected with the recombinant, as the approximate 23 kDa specific band in Western blotting analysis. This study showed the... |
