Outline of Final Research Achievements

The subjects were children who developed early-onset GBS disease (EOGBSD) or late-onset GBS disease (LOGBSD) and their mothers from 5 institutes between 2007 and 2016. There were 14 cases of EOGBSD and 17 cases of LOGBSD, inborn cases were 4 cases both EOGBSD and LOGBSD, with estimated incidence of 0.10 per 1,000 live births for both EOGBSD and LOGBSD. We divided the study period into two parts; the period before (period I: 2007-2008) and after (period II: 2009-2016) issue of the guideline for prevention of vertical transmission in Japan. The incidence of EOGBS was significantly lower in period II (0.03 per 1,000 births) than in period I (0.42 per 1,000 births) (p = 0.02). The incidence of EOGBSD would further decline with proper timing of GBS screening, sampling site, culture method, and appropriate antibacterial prophylaxis for pregnant GBS carriers.
