2025年2月から5月のテキサス州におけるネイスリア・メンニンジティス結膜炎の発生
MMWR. Morbidity and mortality weekly report
|September 4, 2025
まとめ
ワクチン接種にもかかわらず,軍人研修生で髄膜炎の発生が発生しました. 局所的な抗生物質はほとんどの症例で有効であり,この珍しい細菌性眼感染症の治療に変化を起こす可能性を示唆しています.
科学分野:
- 眼科について
- 感染症
- 微生物学
背景:
- 細菌性結膜炎はウイルス性またはアレルギー性より健康な成人に少ない.
- ネイセリア髄膜炎は,細菌による結膜炎の珍しい原因です.
- 共同体の環境での結膜炎の発生は,病原体と効果的な治療法を調査する必要があります.
研究 の 目的:
- 研修生の中での 髄膜炎の発生を調査する
- ネイセリア・メンニギティス菌株の特徴を特定する.
- 髄膜炎の異なる治療法の有効性を評価する.
主な方法:
- 軍事訓練生における結膜炎の症例の特定と疫学的調査
- バクテリア培養と全ゲノムシーケンシング
- 抗生物質の使用を含む患者の治療と結果の臨床レビュー
主要な成果:
- 予防接種を受けた研修生では41例の髄膜炎が発生した.
- 全ゲノム配列解析は,封じ込まない (グループ化できない) N. meningitidis株を示した.
- ほとんどの患者は局所抗生物質にうまく反応し,1人は入院と静脈内投与が必要でした.
結論:
- グループ化できないネイセリア髄膜炎は,ワクチン接種した個人でも,共同での結膜炎の発生を引き起こす可能性があります.
- 局所抗菌薬は,合併症のないN. meningitidisの結膜炎の治療に十分である可能性があります.
- 培養と全ゲノム配列化は,発症の原因を特定し,粘膜炎発症の対応を導くための貴重なツールです.

Transmission-based Precautions II: Airborne and Protective Environment
1.5K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Sexually Transmitted Infections
410
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
