The information supplied on this website and in our information materials is based on published research on GBS from around the world plus, where that is not available, the experience and expertise of our medical panel and other experts in the field. We are always on the look out for new research papers being published to keep our information up-to-date. You may be interested in our recent report (click here for Screening will save newborn lives: A case for the introduction of routine screening for GBS in late pregnancy).

If you would like a more detailed list of abstracts, then please click on this link to PubMed – there are over 8,000 papers listed, although not all are relevant.
