The difference between a yeast infection and bacterial vaginitis is the organism that is causing the infection. So, if the bacteria is growing out, whether it's a sexually transmitted disease or it's a bacteria that has come up to the vaginal area, and it's causing a discharge or smell or infection; that is a bacterial vaginitis--the overgrowth of a bacteria, either from the vagina or from an external environment. And a yeast infection is an overgrowth of the yeast population in the vaginal area.
