まとめ
メチシリン耐性黄色のステーキ菌 (MRSA) の鼻伝染は,HIV感染者 (PLWH) の35. 63%で確認された. 最近の呼吸器感染症と抗レトロウイルス治療の欠如は,感染制御戦略に情報を与える危険因子でした.
科学分野:
- 感染症
- 微生物学
- 公衆衛生
背景:
- HIV感染者 (PLWH) は感染に弱い集団です.
- メチシリン耐性ステロコクス・オーレウス (MRSA) は,医療関連の感染のリスクが大きい.
- PLWHにおけるMRSAの分布と危険因子の理解は,標的型予防に不可欠です.
研究 の 目的:
- PLWHにおけるMRSAの分布を調査する
- PLWHにおけるMRSA鼻菌のコロニー化のリスク要因を特定する.
- PLWHにおける病院で得られたMRSA感染に対する予防戦略を策定する.
主な方法:
- 2022年1月から2024年12月までの1,100 PLWHの横断研究
- S. aureusの特定と抗菌感受性検査のために採取された鼻のスランプ.
- ウイルス性遺伝子の検出に使用されたPCR; Stata13.0を用いた統計分析.
主要な成果:
- PLWHの25%はS. aureus (98 MRSA,177 MSSA) でコロニー化されていた.
- MRSAのキャリアは高齢 (51. 32歳対44. 26歳) で,一般的な抗生物質に対する高い耐性を示した.
- MRSAコロニー化の危険因子には,以前の呼吸器感染症,抗レトロウイルス治療の欠如,および異性交による感染が含まれる.
結論:
- PLWHではMRSAの鼻経輸送が一般的であり,特定の危険因子が特定されています.
- この発見は,この高リスク集団における標的型感染対策を支持する.
- 研究は,PLWHの間でMRSAの発生率と拡散を減らすための基礎を提供します.

Factors Affecting the Risk of Infection
12.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Pulmonary Tuberculosis I
321
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Sputum Studies II: Culture and Sensitivity
580
Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
