Zusammenfassung: | The present invention relates to a microorganism of the genus Salmonella spp. and specifically Salmonella enteritidis 3934, from which the waaL. and nlpl genes have been deleted. The composition composed of said microorganism and/or the outer membrane vesicles (OMVs) derived therefrom, constitutes the basis of a vaccination and surface antigen display system, which has proven useful in preventing or treating pathologies. Likewise, the present invention relates to the methods of generating Salmonella spp. ΔwaaL Δnlpl microorganisms and vaccines, to the method of isolating the corresponding OMVs, and to the use of the corresponding compositions and vaccines as a preventive and treatment system for pathologies in animal organisms and in particular in humans.

La presente invención se refiere a un microorganismo del género Salmonella spp. y específicamente Salmonella enteritidis 3934, de los que se han delecionado los genes waaL. y nlpl. La composición compuesta por dicho microorganismo y/o las vesículas de membrana externa (OMVs) derivadas del mismo, constituye la base de un sistema vacunal y de exposición de antígenos en superficie, que ha demostrado utilidad para prevenir o tratar patologías. Asimismo, la presente invención se refiere a los métodos de generación de los microorganismos y vacunas de Salmonella spp. ΔwaaL Δnlpl, al método de aislamiento de las correspondientes OMVs, y al uso de las correspondientes composiciones y vacunas para como sistema preventivo y de tratamiento de patologías en organismos animales y en particular en humanos. |
