gt;gt; Rachel Gorwitz: Hello,I am Rachel Gorwitz, Medical Officer in the Divisionof STD Prevention at the Centers for Disease Controland Prevention. Although most Chlamydia casesreported are among teens and young adults, any sexuallyactive person can get this sexually transmitteddisease or STD. In fact, CDC estimates thereare nearly 3 million new cases of Chlamydia each year.
People get Chlamydia byhaving vaginal, anal, or oral sex withsomeone who has this STD. Most people withChlamydia have no symptoms which is why the infectionoften goes undiagnosed. If symptoms occur, theymay not appear until weeks after having sex withsomeone who is infected. Women with Chlamydia may havean abnormal vaginal discharge or burning sensationwhen urinating.
Men with Chlamydia may havea discharge from the penis or a burning sensationwhen urinating. Even when a chlamydial infectiondoes not cause symptoms, if left untreated it can go on to cause pelvic inflammatorydisease, chronic pelvic pain or make it difficultor impossible for a woman to get pregnant. CDC recommends thatsexually active women
under age 26 be testedfor Chlamydia every year. It is important forboth men and women to discuss their sexualhistory with their physician to determine if they shouldbe tested for Chlamydia. Chlamydia can be cured easilywith antibiotics prescribed by a healthcare provider. Even after treatment thougha person can be reinfected if they have sex withsomeone who has Chlamydia.
So it's important that sexpartners are also treated. Learn more about Chlamydia andother STDs at cdc.govSTD.
What is bacterial vaginosis
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,
