B群溶連菌感染症（Streptococcus agalactiaeor GBS）は、新生児の罹患率と死亡率の主要な原因として知られている。母子間でのGBSのコロニー化・感染における水出しの役割は不明である．我々は，GBS 陰性の女性が GBS 乳腺炎を発症した際に，水出産で生まれた母乳のみで育てられた全期乳児の一例を紹介する．この乳児は重度の晩発性GBS髄膜炎/敗血症性ショックを呈し，その後，致死的な壊死性腸炎を発症した．GBS感染における水出産の潜在的な役割に関する文献がレビューされている。

Group B Streptococcus (Streptococcus agalactiae or GBS) infections are known as a leading cause of morbidity and mortality in the neonatal population. The role of water birth in colonizing and transmitting GBS between mother and infant is unclear. We present a case of an exclusively breastfed full-term infant, born via water birth, to a GBS-negative woman who developed GBS mastitis. The infant presented with severe, late-onset GBS meningitis/septic shock and subsequently developed fatal necrotizing enterocolitis. Literature regarding the potential role of water birth in GBS transmission is reviewed.
