Detailed Description
-----------------
Deeply influenced of bacterial vaginosis infection during pregnancy for pregnant women and fetus during childbirth, in which Group B Streptococcus agalactiae(GBS) is generally about 30% of pregnant women will be infected, about 1% vertical and infect the fetus, babies are not infected about 50% of the mortality rate in the treatment status, is considered an important reason for infection and death before and after the baby is born.
