What you do have to know is all three. So keep them together. We have a fungal infection causing vaginosis, that was candidal. Number two, we had a protozoal, that was trichomonas. And thirdly, we have a bacterial. Allow the name to perhaps help you out a little bit. We have a Gardnerella vaginalis. So here, you have now laid out a garden full of gram-negative bacteria. The garden has now gotten old the everything in the garden has died and giving you a malodorous, thick-gray -- well, in this case, it will be vaginal discharge if that helps you. This is the one in which you would expect to smell something malodorous with a bacterial vaginosis called Gardnerella vaginalis. Some would say this would be the most common, but as I told you earlier, this would not be your focus. The three major types of vaginosis, know them all. Not truly considered to be an STI or STD. And here, decreases in hydrogen peroxide producing lactobacilli and cause -- Well, that increase in pH is the environment that this organism loves to thrive in. There are different reasons as to why the pH within the vagina would increase. Well, you have a female who's been repeatedly douching. And if she's douching then perhaps her pH increases.
