11 February 2008	Amended	Converted to new review format.
1 September 2007	New search has been performed	The update of the literature search in September 2007 identified two studies published in abstract form and two ongoing studies. All four were randomized controlled trials of the use of vaginal chlorhexidine in labour to prevent neonatal infection. Neither of the two studies published in abstract form, nor the two ongoing studies have identified maternal colonization with group B streptococcus as an entry criterion. Therefore, no new information was found and our conclusions remain the same as in the original review.
