The genus Vibrio is one of the best model marine heterotrophic bacterial groups, and many Vibrio species grow very quickly with short generation times. In addition, many Vibrio spp. are well-known bacterial pathogens, causing ...

Why is it that Mycobacterium tuberculosis can cause tuberculosis with as little as 10 cells, whereas Vibrio cholerae requires the host to ingest up to tens of millions of cells to cause cholera? This is the question that ...
