Research Abstract

急性中耳炎患児から分離された無莢膜型インフルエンザ菌がバイオフィルム形成を行うことが明らかとなり、加えて無莢膜型インフルエンザ菌のバイオフィルム形成が、抗菌薬治療に抵抗し遷延・難治化する急性中耳炎の臨床経過に重要な役割を果たすことが示された。さらに溶連菌の細胞内侵入遺伝子の検討では、sil遺伝子の発現が12%の株に認められ、抗菌薬治療後の感染再発が上気道粘膜内に侵入した細菌の再活性化による可能性が示唆競れた。免疫予防の可能性として、肺炎球菌菌株共通抗原であるPspAの母体経鼻免疫免疫により、免疫能の未熟な乳幼児期に特異的免疫応答が誘導可能であり、乳幼児期における肺炎球菌感染症の予防方法として有用と考えられた
