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,
Cell vs virus A battle for health Shannon Stiles
You're in line at the grocery store when, uh oh, someone sneezes on you. The cold virus is sucked inside your lungs and lands on a cell on your airway lining. Every living thing on Earth is made of cells, from the smallest onecelled bacteria to the giant blue whale to you. Each cell in your body is surrounded by a cell membrane,
a thick flexible layer made of fats and proteins, that surrounds and protects the inner components. It's semipermeable, meaning that it lets some thing pass in and out but blocks others. The cell membrane is covered with tiny projections. They all have functions, like helping cells adhere to their neighbors
or binding to nutrients the cell will need. Animal and plant cells have cell membranes. Only plant cells have a cell wall, which is made of rigid cellulose that gives the plant structure. The virus cell that was sneezed into your lungs is sneaky. Pretending to be a friend, it attaches to a projection on the cell membrane, and the cell brings it through the cell membrane and inside.
When the virus gets through, the cell recognizes its mistake. An enemy is inside! Special enzymes arrive at the scene and chop the virus to pieces. They then send one of the pieces back through the cell membrane, where the cell displays it to warn neighboring cells
about the invader. A nearby cell sees the warning and immediately goes into action. It needs to make antibodies, proteins that will attack and kill the invading virus. This process starts in the nucleus. The nucleus contains our DNA,
the blueprint that tells our cells how to make everything our bodies need to function. A certain section of our DNA contains instructions that tell our cells how to make antibodies. Enzymes in the nucleus find the right section of DNA, then create a copy of these instructions, called messenger RNA. The messenger RNA leaves the nucleus to carry out its orders.
