Bacterialvaginosis is a disease that's caused by the overgrowth of a type of bacteria that's called Gardnerella vaginalis, Gardnerella vaginalis. And as the name might suggest, this is the most common vaginal infection. Now I wanna put these really big quotes
around the term infection because the thing that's interesting about Gardnerella vaginalis is that it's a bacteriathat's naturally found in the vagina. Now some may consider this to be a sexually transmitted infection, which is interestingbecause it doesn't cause
any problems until there'stoo much of it there. So when we look to the causes of bacterial vaginosis, they are all things that change the vaginal environment. That can include acts like douching, so douching, or rinsing of the vagina. The other is having newor multiple sex partners.
And finally, another known cause is the use of antibiotics. This could be in the case of somebody that has a throat infection or a pneumonia that's on antibiotics which will then attackthe bacteria that exists within the vagina andallow Gardnerella vaginalis to overgrow and cause bacterial vaginosis.
So we've touched a little bit on it here, but I wanna draw it out. So when we talk about the pathophysiology of a disease, we'retalking about the mechanism by which that disease occurs. So in order to understandthe pathophysiology of bacterial vaginosis, we need to take a look at a sample of bacteria
that exists in the vagina. So I'll draw out someGardnerella vaginalis bacteria, and so I'll put this up in our key. This is the symbol forGardnerella vaginalis. And I'll draw a few of them around here, but I also wanna show that there are a lot of other bacteriathat exist in this sample. So if you really look at it here,
Oh hi! As you may havenoticed, your vagina does not come with an owner's manual. Although, I can tellyou that would have been really helpful and saved me a lot of infections growing up. Vaginas work basically like this. It's like a little ecosystem. It maintains and cleans itself.
The actual vagina, the inside, you never have to clean in there. And you don't ever wantto put anything in there. Well, nothing to clean in there. That includes douches,soaps, bleach. (squeals) What all that stuff doesis go all up in there, and it (bleep) everything up. And the vagina has good bacteria that
keeps you clean and healthy. By introducing soap ordouching, you kill off that good bacteria, and youcan mess up the delicate pH balance of the vagina, whichcan cause a yeast infection or also something calledbacterial vaginosis, which is characterized by a fishy smell. You can also get urinarytract infections from getting soap around your rurethra, your urethra.
Yeah, I can talk! So, any time you see thesoap, it's coming towards your vagina, you say, quot;Get away, soap! quot;We are not cool, be gone!quot; Now, in terms of keepingthe outside clean, the proper way to clean your vulva is to gently spread your labia or the lips, and then use some warm water and your hand
to gently rub betweenthe folds and clear off all the sweat and bacteria. quot;So, you mean I shouldn't use shampooéquot; No. quot;What about shaving creaméquot; Only on the hair part. quot;What about toothpasteéquot; That's for your teeth.
quot;Oh yeah.quot; Vaginas are not nearly asdirty as people think they are. You want dirtyé Probe someone's mouth. Warm water, your hands,a washcloth, or a loofah. That's all you need to stay clean. I swear on my vagina! I think a lot of the reasonwhy people scrub vigorously
