Abstract:
The present invention relates to a Lyme disease vaccine, a genetic construct, recombinant protein, method for genetic construct design, method for vaccine delivery, method for recombinant proteins delivery, use of recombinant proteins in the production of Lyme disease vaccine. In particular, the method concerns the use of TROSPA and TROSPA- Salpl 5 recombinant proteins derived from castor bean tick {Ixodes riccinus) as a component of Lyme disease vaccine for animals. The antibodies present in blood of an immunized vertebrate directed against the TROSPA proteins considerably reduce the chance of infecting new ticks by blocking or hindering the interaction of TROSPA protein with OspA protein of Borrelia burgdorferi sensu lato. The interaction is crucial in the process of the spirochete entering a tick. The antibodies directed against the TROSPA- Salpl5 protein protect vertebrates from infection on the stage of Borellia diffusion by destroying their protective coating formed at the surface as a result of the interaction between the Salpl5 tick protein and OspC spirochete protein. The vaccine based on TROSPA tick proteins and TROSPA-Salpl5 proteins may be used independently or together with the OspA recombinant proteins and OspC protein of Borrelia burgdorferi sensu lato.
Abstract:
Se ha procedido a la obtención de una proteína recombinante (rHc23) de H. contortus tras comprobar que la proteína nativa Hc23, de 23kDa de peso molecular, originaria del extracto soluble de adultos del nematodo hematófago H. contortus ha mostrado capacidad inmunoprotectora en el ganado ovino joven de 5 meses de edad frente a la trichostrongilidosis más importante (hemoncosis) desde un punto de vista económico y patológico. Se ha caracterizado la proteína Hc23, obteniéndose las secuencias aminoacídicas y genómicas de la misma, permitiendo, por técnicas de biología molecular, ADN recombinante, la producción de una proteína estable, la rHc23. Su utilización en composiciones inmunogénicas que incluyen como adyuvante la combinación de Propionibacteríum acnés inactivado + lipopolisacáridos de E. coli ha mostrado un elevado grado de protección en los animales (>85% de protección).
Abstract:
The present invention relates to antigens capable of raising host immune responses to parasites. In particular, the invention provides, vaccines for use in protecting against and/or reducing instances of parasite infection in avian hosts.
Abstract:
Two antigenic and immunogenic proteins of the cattle tick, Rhipicephalus microplus, and the genes encoding these proteins, are effective for eliciting a protective immune response that controls and prevents infestations of bovines and other livestock by the tick. The proteins isolated from the cattle tick include an aquaporin protein and a TC5777 gut membrane protein. Each of the proteins elicit an immunoprotective response in livestock to the cattle tick, and can be formulated and administered as vaccines. Alternatively, the isolated DNA sequences which encode these proteins can be incorporated into nucleic acid constructs which could be utilized as DNA vaccines. The nucleic acid constructs can also be used for the transformation of cells and the production of recombinant proteins. Induction of the protective immune response controls and prevents infestations of the treated animals with the tick, thereby protecting them against tick-borne pathogen transmission.
