Abstract

Fungal infections are currently causing health issues all over the world, among which are species that cause cutaneous infection. Numerous dermatological studies concentrated on a single species. However, the virulence factors and the spread of specific candidiasis in specific areas have remained poorly understood. Therefore, the current study was designed to shed light on , which has been identified as the most prevalent yeast among non- species. Forty specimens were collected from patients with cutaneous fungal infection (25 females and 15 males) and underwent examination. According to conventional identification based on macroscopic and microscopic examinations, eight isolates were identified as from non-. Molecular diagnosis for internal transcribed spacers (ITS1 and ITS4) using conventional polymerase chain reaction (PCR) yielded an amplicon of 520 bp for all isolates. Further investigation of PCR-restriction fragment length using Mitochondrial sorting protein; Msp1 enzyme revealed two bands of 340 and 180 bp. The ITS gene sequence in one isolated species was found to be 98% identical to strain MYA-3404 chromosome R ATCC CP047875.1. Another isolate shared 98.02% identity with strain MA6 18S ribosomal RNA gene DQ666188.1, indicating species identity, implying that non- species should be considered when diagnosing candidiasis. This study demonstrated the significance of non-, particularly , in terms of pathogenic potential, the ability to cause potentially fatal systemic infections and candidiasis, and acquired flucozonal resistance with a high mortality rate.

摘要

真菌性感染目前在全球范围内引发了健康问题,其中包括引起皮肤感染的物种。许多皮肤科研究都集中在单一物种上。然而,特定念珠菌病的毒力因素和在特定地区的传播仍了解甚少。因此,本研究旨在阐明,它已被确定为非-物种中最普遍的酵母。从患有皮肤真菌感染的患者(25 名女性和 15 名男性)中采集了 40 个标本并进行了检查。根据基于宏观和微观检查的常规鉴定,从 非-中鉴定出 8 个分离株为 。使用常规聚合酶链反应(PCR)对内部转录间隔区(ITS1 和 ITS4)进行分子诊断,所有分离株均产生 520 bp 的扩增子。使用线粒体分拣蛋白;Msp1 酶对 PCR 限制性片段长度的进一步研究显示,两个带分别为 340 和 180 bp。在一个分离种的 ITS 基因序列与 MYA-3404 菌株的染色体 R ATCC CP047875.1 的 98%相同。另一个分离株与 菌株 MA6 18S 核糖体 RNA 基因 DQ666188.1 共享 98.02%的同一性,表明为 种,这表明在诊断念珠菌病时应考虑非-物种。本研究表明了 非-,特别是 的重要性,包括其致病潜力、引起潜在致命性全身感染和念珠菌病的能力,以及具有高死亡率的氟康唑抗性获得。
