What does "Group B Streptococcus" mean?
Table of Contents
Group B Streptococcus (GBS) is a type of bacteria commonly found in the bodies of healthy adults, especially in the intestines and the genital tract. While it usually does not cause problems, it can lead to serious infections in newborns.
How It Affects Newborns
When a mother carries GBS, her baby can be exposed to the bacteria during childbirth. This exposure can sometimes lead to invasive Group B streptococcus disease (IGbsD), which can cause severe health issues in infants, especially those under 90 days old.
Importance of Antibodies
Antibodies are proteins made by the immune system to fight off infections. Mothers can pass protective antibodies to their babies during pregnancy. Research shows that higher levels of certain antibodies in infants against GBS proteins are linked to a lower risk of IGbsD.
Potential for Vaccines
Scientists are looking into ways to develop vaccines against GBS to help protect newborns. By focusing on the surface proteins of GBS that trigger antibody responses, they aim to create vaccines that could reduce the chances of newborns getting sick from this bacteria.
