[Abstract]  The greater wax moth Galleria mellonella has emerged as an effective heterologous host to study fungal pathogenesis and the efficacy of promising antifungal drugs (Mylonakis et al., 2005; Li et al., 2013). Here, a methodology describing the Aspergillus nidulans infection in G. mellonella larvae, along with insect survival analysis, is reported. This protocol allowed the distinction between virulent A. nidulans strains (such as TNO2A3), which induced high larval mortality rates, to those in which gene deletion was accompanied by reduced pathogenicity such as ∆gcsA and ∆sdeA (Fernandes et al., 2016). [摘要]  作为一种有效的异源宿主,越来越多的蜡蛾已经出现了一种有效的异源宿主,用于研究真菌发病机制和有希望的抗真菌药物的功效(Mylonakis等人,2005; Li& et al。2013)。这里,描述了一种描述构巢曲霉感染的方法。 mellonella 幼虫与昆虫存活分析一起报道。该协议允许区分有毒的 A。造成高幼虫死亡率的构巢组织菌株(如TNO2A3)与基因缺失伴随着致病性降低的病例如ΔGCA和ΔSAA(Fernandes 等人,2016)。

背景 -G。 mellonella 是一种廉价的模型,易于处理,其先天免疫反应与哺乳动物免疫系统分享功能相似性。此外,感染真菌突变菌株的幼虫和小鼠表现出相似的存活率(Brennan等人,2002)。因此,幼虫构成了一种方便的动物宿主,用于在真菌发病机理分析中代替脊椎动物的使用。尽管昆虫模型具有所有优点,但只有少数报告显示了G中曲霉菌感染的作用。蜡螟。该协议描述了一种有效的方法,用于分析G中的构巢曲霉发病机制。 mellonella 幼虫。
