RESUMEN

El flagelo bacteriano es un organelo de locomoción ampliamente utilizado entre los organismos procariontes, constituye una ventaja adaptativa y es un factor muy importante tanto para la colonización de nichos como para la patogénesis. El flagelo es un heteromultímero formado por alrededor de 30 diferentes proteínas y está dividido en tres subestructuras: filamento, gancho y cuerpo basal. En este trabajo de revisión, describiremos la estructura, biogénesis y funcionamiento del flagelo de las bacterias marinas del género Vibrio y explicaremos cómo se desplazan en medio líquido haciendo uso del flagelo polar, cuya rotación está acoplada a un flujo de iones sodio (Na⁺) y cómo algunas otras especies del género como Vibrio alginolyticus, Vibrio parahaemolyticus o Vibrio shilonii, son capaces de expresar, adicionalmente al desplazarse en medio sólido, un sistema de flagelos laterales cuya rotación está acoplada a un flujo de protones (H⁺).
