By employing electrospray ionization tandem mass spectrometry (ESI-MS/MS), the phospholipidomes of eight hemiascomycetous human pathogenic Candida species have been characterized. Over 200 phospholipid molecular species were identified and quantified. There were no large differences among Candida species in phosphoglyceride class composition; however, differences in phosphoglycerides components (i.e., fatty acyl chains) were identified. In contrast, differences in sphingolipid class composition as well as in molecular species were quite evident. The phospholipid compositions of C. albicans, C. glabrata, C. parapsilosis, C. kefyr, C. tropicalis, C. dubliniensis, C. krusei, and C. utilis could be further discriminated by principal component analysis. Notwithstanding that a single strain of each species was analyzed, our data do point to a typical molecular species imprint of Candida strains.
采用电喷雾串联质谱法(ESI-MS/MS),对八种半子囊菌属人致病性念珠菌的磷脂组进行了表征。鉴定和定量了超过 200 种磷脂分子种类。在磷酯酰基甘油类别组成方面,各念珠菌种之间没有很大差异;然而,鉴定到了磷酯酰基甘油成分(即脂肪酸链)的差异。相反,鞘脂类别组成以及分子种类的差异非常明显。通过主成分分析,可以进一步区分白念珠菌、光滑念珠菌、近平滑念珠菌、卡氏酵母、热带念珠菌、都柏林念珠菌、克柔念珠菌和酿酒酵母的磷脂组成。尽管分析了每种菌的单个菌株,但我们的数据确实表明了念珠菌菌株的典型分子种类特征。
