The standard procedure for the detection of candidemia is blood culture, a method that might require 3-5 days for a positive result. Compared with culturing, molecular diagnosis techniques can provide faster diagnosis. The current paper aimed to present the main strengths and constraints of current molecular techniques for spp. DNA extraction, analyzing their efficiency from a time, price, and ease of usage point of view. A comprehensive search was conducted using the PubMed NIH database for peer-reviewed full-text articles published before October 2022. The studies provided adequate data on the diagnosis of the infection with the spp. DNA extraction is a relevant step in yielding pure qualitative DNA to be amplified in molecular diagnostic techniques. The most used fungal DNA extraction strategies are: mechanical (bead beating, ultrasonication, steel-bullet beating), enzymatic (proteinase K, lysozyme, lyticase), and chemical extraction (formic acid, liquid nitrogen, ammonium chloride). More clinical studies are needed to formulate adequate guidelines for fungal DNA extraction as the current paper highlighted discrepancies in the reported outcome.
检测念珠菌血症的标准方法是血培养,这种方法可能需要3至5天才能得到阳性结果。与培养法相比,分子诊断技术能够提供更快的诊断。本文旨在阐述当前用于[物种名称]DNA提取的分子技术的主要优势和局限性,从时间、价格和易用性角度分析其效率。利用美国国立医学图书馆的PubMed数据库对2022年10月之前发表的同行评议全文进行了全面检索。这些研究提供了关于[物种名称]感染诊断的充分数据。DNA提取是获得纯定性DNA以在分子诊断技术中进行扩增的一个相关步骤。最常用的真菌DNA提取策略有:机械法(珠磨法、超声破碎法、钢珠研磨法)、酶解法(蛋白酶K、溶菌酶、裂解酶)和化学提取法(甲酸、液氮、氯化铵)。由于本文强调了报道结果中的差异,因此需要更多临床研究来制定关于真菌DNA提取的适当指南。
