概括
一种导致皮肤感染的真菌Trichophyton indotineae在比利时出现. 这种耐药性与烯环氧化酶 (SQLE) 基因突变有关,需要持续监测和向治疗.
科学领域:
- 医学真菌学 医学真菌学
- 抗微生物耐药性 抗微生物耐药性
- 基因组学就是基因组学.
背景情况:
- 与T.interdigitale和T.mentagrophytes相关的皮肤植物Trichophyton indotineae越来越普遍,并且表现出高的特尔比纳耐药性.
- 在欧洲出现的T. indotineae需要加强监测,因为它具有抗性机制,主要涉及烯环氧化酶 (SQLE) 基因.
- 皮肤细胞中terbinafine耐药性是一个日益增长的全球健康问题,影响表面真菌感染的治疗疗效.
研究的目的:
- 为了确定T. interdigitale,T. mentagrophytes和T. indotineae在比利时的流行率和抗真菌易感性.
- 调查这些皮肤植物物种中与特尔比纳芬耐药性相关的SQLE基因替代物的存在.
- 对临床分离物进行基因组学分析,以了解遗传关系和种群结构.
主要方法:
- 使用EUCAST E.Def.11.0方法对137个临床分离物进行抗真菌敏感性测试.
- 全基因组测序 (WGS) 使用Illumina技术进行详细的遗传分析.
- 遗传学分析以区分和分类Trichophyton物种并识别遗传标记.
主要成果:
- 遗传学分析发现了8种T. indotineae,91种T. interdigitale和38种T. mentagrophytes的分离物.
- 在5.1%的隔离物中观察到特比纳芬耐药性,主要在T. indotineae (87.5%),与SQLE替代物一致相关.
- T. interdigitale 隔离物对特尔比纳完全敏感,而 T. mentagrophytes 显示轻微升高的最小抑制度 (MIC),通常与 K276N SQLE 替代物相关.
结论:
- 在比利时,抗特尔比纳耐药的T. indotineae正在出现,主要是通过进口病例.
- 证实SQLE基因替代是T. indotineae.中特尔比纳芬耐药性的主要机制.
- 持续的分子监测和物种特异性治疗策略的开发对于管理耐特巴纳皮肤植物病至关重要.

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
