概括
目前,Trichophyton indotineae是伊朗皮肤植物病的主要原因,由于烯环氧化酶基因突变,它经常表现出对terbinafine的耐药性. 这凸显了持续监测和谨慎使用抗真菌药物的必要性.
科学领域:
- 医学真菌学 医学真菌学
- 传染性疾病 传染性疾病
- 遗传学 是一个遗传学.
背景情况:
- 皮肤植物病是一种普遍存在的全球性皮肤感染.
- 三植物 (Trichophyton mentagrophytes var.) 是一种不同的植物. 印丁菌是难以治疗的皮肤植物病的新兴原因.
- 关于伊朗皮肤植物病流行病学的全国数据有限,尽管观察到遗传多样性.
研究的目的:
- 调查伊朗当前皮肤植物病的流行病学.
- 识别主导性皮肤植物物种及其临床关联.
- 分析与特尔比纳耐药性相关的烯环氧化酶 (SQLE) 基因突变.
主要方法:
- 这是一项为期一年的多中心,基于医院的调查,涉及伊朗9个省份2211名患者.
- 使用特定物种PCR和ITS测序进行物种识别.
- 用SQLE基因测序来检测与耐药性相关的突变.
主要成果:
- 皮肤菌从71%的样本中恢复,T. indotineae在76%的病例中被确定,使其成为主要的病原体.
- 印度丁菌与各种临床形式有关,包括 tinea cruris, corporis 和通用感染.
- 与耐药性相关的突变 (F397L和L393S) 在45%的T. indotineae分离物中被发现,特别是在南部省份.
- 在T. indotineae.中确定了两个ITS基因型 (VIII和一个新的亚基因型XXIX).
结论:
- 印丁菌是伊朗占主导地位的皮肤植物,对反抗性感染的负担作出了重大贡献.
- 由于SQLE突变的高患病率导致了对terbinafine的耐药性,因此需要紧急进行分子监测.
- 这些发现支持当地的传染正在进行中,并强调了对抗真菌管理的需要.

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...

Fungal Phylum Microsporidia

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...
