“…Early R. microplus embryonic stages are typical of the D. melanogaster model system, and have also been observed in mosquitoes (Bate and Arias, 1991;Monnerat et al, 2002). Tick embryogenesis is characterized by the formation of a non-cellular syncitium up to day 4 (Campos et al, 2006). After this, the embryo becomes a multicellular organism and starts organogenesis (Campos et al, 2006).…”

“…In addition, at the end of embryogenesis the glucose is obtained from the amino acid catabolism. Surprisingly, in the eggs this process is accompanied by a significant glycogen re-synthesis (CAMPOS et al, 2006). These data suggest the existence of a rather complex system of control of energy metabolism in the embryogenesis of this tick.…”

“…It was observed that total egg protein remains stable during embryogenesis (CAMPOS et al, 2006), while VT content suffers a variation (CANAL et al, 1995;LOGULLO et al, 2002). Thus, VT is used for the supply of the amino acids required to synthesize new proteins.…”

The tick Rhipicephalus (Boophilus) microplus (formerly Boophilus microplus) is the major ectoparasite affecting livestock in America, Asia, Africa, and Oceania. Conventional tick control is based on the use of acaricides but immunization of bovines with tick gut proteins induces only a partial protective immune response. Based on this information, distinct research groups have explored the possibility of protecting the animals by inducing an immune response against other tick proteins. However, the antigens so far described do not induce the necessary protection for suppressing the use of acaricides. Currently, several groups are engaged in identifying new tick proteins to be used as targets for the development of new vaccines. This approach focuses on the enhancement of the immunogenicity of antigens already tested by incorporating new adjuvants or formulations and by searching for new antigens. This paper reviews the work done by Brazilian researchers to develop a vaccine against this tick.Keywords: Boophilus microplus, Rhipicephalus microplus, vaccine, tick, control. ResumoO carrapato Rhipicephalus (Boophilus) microplus (anteriormente Boophilus microplus) é o principal ectoparasita que afeta bovinos na América, Ásia, África e Oceania e o seu controle é tradicionalmente realizado através do uso de acaricidas. Experimentos de imunização com proteínas do carrapato mostram que a resposta imune desenvolvida pelos bovinos vacinados protege, em parte, os animais do parasitismo. Baseado nessas observações, vários grupos de pesquisa exploram a possibilidade de proteger os animais pela indução de uma resposta imune contra proteínas do carrapato. Entretanto, os antígenos já caracterizados não asseguram o grau de proteção necessário para suprimir o uso de acaricidas. Portanto, esses grupos de pesquisa estão engajados na tentativa de identificar novas proteínas que possam ser utilizadas para o desenvolvimento de novas vacinas, as quais possam induzir maior imunogenicidade de que os antígenos já testados, através do uso de novas formulações e/ou pela incorporação de adjuvantes. O presente artigo apresenta uma revisão da literatura sobre os resultados obtidos por pesquisadores brasileiros no desenvolvimento de vacinas contra o carrapato.
