I actually had to go to the doctor this morning to do my testing for Strep B. While I was there they gave me a spreadsheet with facts about Strep B so I'll share what info they provided for me.
1. Strep B (Streptococcus) is a bacteria which can be present in the lower intestinal tract and vagina of 1 out of every 3-5 women. It is NOT a sexually transmitted infection, and usually causes no illness in the adult, although it is associated with urinary tract infections.
2. 1-2 out of every 1000 newborn babies will develop an infection during the first few days of life and in most cases this is due to Group B Strep, which may be transmitted from the mother. This infection is treatable but can sometimes cause very serious illness or death.
3. In an effort to help prevent this infection your care provider will offer to preform a culture of the vagina and rectum during the ninth month of pregnancy to determine if you carry the bacteria. If the test is positive we will advise you to receive antibiotics during labor. If the test is negative the likelihood of Group B Strep being present during labor is very low. This method of treatment will help lower the risk of the newborn infections.
4. There may be other factors besides a positive culture that may indicate the need for antibiotics during labor. If you have had a previous child with a newborn infection make sure your care providers are aware.
5. Group B Strep is fairly common in pregnant women. Fortunately very few babies become infected. Through the use of antibiotics in selected individuals during labor the relative low risk of Group B Strep infection in newborns can be made even less.
Hope this helps a little I'm from the US and this was some info that was passed along to me from my OB. xx
