Desarrollo y aplicación de sistemas vector/hospedador en bifidobacterias

Desarrollo y aplicación de sistemas vector/hospedador en bifidobacterias

Abstract

[ES] Las bifidobacterias constituyen una de las poblaciones microbianas dominantes en el intestino humano y de otros animales, donde ayudan a mantener el equilibrio microbiano por medio de sus variadas actividades metabólicas, contribuyendo a mantener y preservar el estado de salud. El conocimiento de estos mecanismos de probiosis es fundamental para apoyar científicamente las supuestas acciones beneficiosas y el diseño y utilización racional en los probióticos. Para llevar a cabo este propósito son necesarios sistemas vector/hospedador adecuados así como mecanismos eficientes de transferencia génica. El conocimiento acerca de los plásmidos de bifidobacterias así como su caracterización molecular se revela fundamental para el desarrollo de nuevas y más versátiles herramientas genéticas para el género Bifidobacterium.

[EN] Bifidobacteria are members of the normal intestinal microbiota of animals and humans, where they are thought to play positive health-promoting effects. Unravelling the mode of action of their probiotic properties is essential to scientifically support their rational application. For this purpose, suitable host/vector systems and appropriate gene transfer techniques are required. Increased knowledge of bifidobacterial plasmids and their molecular characterization is still needed for the development of new and more versatile genetic tools for Bifidobacterium.
