ソフトボールチームのメンバーの1人は、1週間前の試合当日は元気だったが、突然治療のため入院した。病名は「肺蓄膿症（肺膿瘍、化膿性肺炎）」で、肺に腫瘍ができることで起こります。口腔内の嫌気性細菌が肺に移動することで起こるようですが、原因の多くは口腔内の細菌（特に嫌気性細菌）の感染や、口腔内が不潔であったり虫歯を放置したりした場合に起こります。飲み込むと、多くの細菌が肺に侵入したり、血流に乗って肺に侵入したりして、肺膿瘍を引き起こす可能性が高くなります。細菌に効果のある抗菌薬を投与することで治療します（第一選択はβ-ラクタム/β-ラクタマーゼ阻害薬の組み合わせです；例：アンピシリン/スルバクタム1～2gを6時間ごとに静脈内注射）。早く元気なって活動再開してほしい。

One of the members of the softball team was fine on the day of the game a week ago, but suddenly she was hospitalized for treatment. The name of the disease is ``pulmonary empyema (lung abscess; purulent pneumonia),'' which is caused by a tumor forming in the lungs. It seems to occur when anaerobic bacteria in the oral cavity migrates to the lungs, but most of the causes are infection by bacteria in the oral cavity (especially anaerobic bacteria), and if the oral cavity is unclean or cavities are left untreated. When swallowed, many bacteria enter the lungs or enter the bloodstream and enter the lungs, making it more likely to cause a lung abscess. Treat by administering an antibacterial agent that is effective against the bacterium (the first choice is a combination of β-lactams/β-lactamase inhibitors; (e.g., ampicillin/sulbactam 1 to 2 g, intravenously injected every 6 hours). It seems to be done using .　　I hope he get well soon and resume his activities.
