Eucalipto, devido o seu rápido crescimento, ampla adaptação às condições de solo e clima e seus usos, tais como papel e celulose, serraria, lenha e carvão, representa, hoje, uma das espécies florestais mais plantadas no Brasil. Entretanto a implantação e a exploração econômica da cultura do eucalipto em locais de ocorrência de geadas na Região Sul, tem sido limitada a poucas espécies, face a baixa tolerância a essa condição climática. Dentre os eucaliptos tolerantes a geada, plantados no sul do Brasil, destaca-se Eucalyptus dunnii que apresenta, ainda, um crescimento médio anual de 4m e 3,2 cm em altura e diâmetro, respectivamente. Isto representa uma produção em volume de madeira de, aproximadamente 109 m3/ha/ano. Apesar dessas vantagens, o E. dunnii apresenta no Brasil uma baixa produção de sementes, o que, no momento, vem dificultando o seu plantio em escala comercial. Como alternativa para propagar essa espécie, COOPER & GRAÇA aperfeicoaram, no Centro Nacional de Pesquisa de Florestas/EMBRAPA, a técnica de produção de mudas através do enraizamento de estacas. |

Purpose In the present study, meningococcal serogroup B outer membrane vesicles (OMVs) were associated with bilayer fragments of a cationic lipid, dioctadecyldimethylammonium (DDA-BF), used as adjuvant, in an antigenic preparation tested in adult female outbred mice. This adjuvant was compared to the traditional adjuvant aluminum hydroxide. Materials and Methods The potential in generating humoral response was evaluated by enzyme-linked immunosorbent assay (ELISA). Individual serum was collected and immunoglobulin G (IgG), IgG1, IgG2a, and IgG2b were quantified. Analyses were carried out 15 and 60 days after immunization. Antibodies avidity index were also analyzed by ELISA. Immunoblot and dot-ELISA were carried out to evaluate specific reaction for homologous strains and cross-reactive antigens present in other meningococcal strains isolated in 2011?2012 year, in Brazil. Delayed type hypersensitivity was used as indicative of cellular immunity and compared between two experimental groups, 24 hours after homologous strain challenge. Results The OMVs of Neisseria meningitidis, and N. lactamica (related species) were characterized by electrophoretic separation of proteins in 13% polyacrylamide gel. The strains presented antigens in the range of 8 to 130 kDa, showing a heterogeneous protein migration pattern. In the group immunized with OMVs/DDA-BF, we found no significant production of total IgG 15 days after the first immunization. On the other hand, 60 days after first immunization both adjuvants act benefiting total IgG production similarly. The antibodies of the IgG isotype produced by animals immunized after one or two doses after first immunization, showed intermediate and high avidity, independent on the adjuvant used. In both experimental groups the swelling of the footpads was significantly higher than those of the controls, suggesting that only one dose was enough to stimulate the generation of cellular immunity. Conclusion The use of this cationic adjuvant for N. meningitidis OMVs preparation revealed good potential for future new antigen preparation for N. meningitidis vaccine.
