So Vibrio simply means it's a raw shape gram negative bacterial cell. In fact, the raw shape is actually curved and so it looks like a comma. Now gram shape, gram negative basically means it contains a very thin layer of peptidoglycan in a cell envelope. And so if we stain it with the color purple, with the purple dye and then wash that purple dye away, that purple dye will not be able to remain in that cell wall and so it will be washed away and the bacterial cell will in fact appear pink under the microscope as shown here. So Vibriocolari are curved, rod shaped grand negative bacteria that can infect human cells and in the presence of oxygen. They will in fact use oxygen to produce ATP molecules in a process we call aerobic cellular respiration.
