耐性菌が疑われる市中肺炎への薬の使い方

著者： 伊藤正仁¹ 柳秀高¹

所属機関： ¹東海大学医学部総合内科

ページ範囲：P.1577 - P.1581

ポイント

●市中肺炎の最大の起因菌である肺炎球菌のペニシリン感受性の定義が変化した結果，ほとんどの肺炎球菌性肺炎をペニシリンで治療することが公式に可能となった．

●髄膜炎におけるペニシリン感受性の定義はほぼ以前と変わりがないことに注意．

●インフルエンザ桿菌にはβラクタマーゼ陰性でもアンピシリン耐性の株（BLNAR）がある．

●緑膿菌のリスクファクターがある患者では重症度，グラム染色などを手掛かりにカバーするかどうかを決める．
