Centromeres ofCandida albicans form on unique and different DNA sequences but a closely related species,Candida tropicalis, possesses homogenized inverted repeat (HIR)-associated centromeres. To investigate the mechanism of centromere type transition, we improved the fragmented genome assembly and constructed a chromosome-level genome assembly ofC. tropicalis by employing PacBio sequencing, chromosome conformation capture sequencing (3C-seq), chromoblot, and genetic analysis of engineered aneuploid strains. Further, we analyzed the 3D genome organization using 3C-seq data, which revealed spatial proximity among the centrom...

c F, Nováková L Abstract The new ultra-high performance liquid chromatography method with tandem mass spectrometry detection (UHPLC-MS/MS) has been optimized to allow fast, selective, and high-throughput analysis of two Candida albicans quorum sensing molecules (QSM), farnesol and tyrosol. The problem of the presence of the interference in the samples and system was successfully solved by careful optimization of chromatographic conditions. Charged hybrid stationary phase modified with pentafluorophenyl group and optimized gradient elution provided adequate separation selectivity and peak shapes. The ...

We report here on a 31 years old female patient suffering from severe mucosal aphthous mucositis and ulcers and recurrent herpes simplex for decades. We found a previously unknown heterozygous sequence variant in STAT1 (c.1219C>G; L407V) affecting the DNA-binding domain of the protein in the patient and her 4 years old daughter. We found this mutation gain-of-function (GOF) by using immunoblot and luciferase assays. We detected low proportion of IL-17A-producing CD4+ T cell lymphocytes by using intracellular staining and flow cytometry. Candida-induced secretion of IL-17A and IL-22 by mononuclear cells from the patient ...

Candida diddensiae, a yeast found in olive oil, is considered non-pathogenic to humans. Here, we describe the first case of fungemia caused by C. diddensiae in a hospitalized patient with underlying diseases.

We report here that isolates of the pathogenic yeast species Candida parapsilosis show within-species polymorphism for the location of centromeres on two of its eight chromosomes. Its old centromeres have an inverted-repeat (IR) structure, whereas its new centromeres have no obvious structural features but are located within 30 kb of the old site. Centromeres can therefore move naturally from one chromosomal site to another, apparently spontaneously and in the absence of any significant changes in DNA sequence. Our observations are consistent with a model in which all centromeres are genetically determined, such as by the ...

Small molecule inhibitors targeting sterol 14α-demethylase (CYP51): synthesis, molecular modelling and evaluation against Candida albicans. ChemMedChem. 2020 May 27;: Authors: Simons C, Binjubair F, Warrilow AG, Puri K, Braidley PJ, Tatar E, Kelly SL, Kelly DE, Parker J Abstract Fungal infections are a global issue affecting over 150 million people worldwide annually with 750,000 of these caused by invasive Candida infections. Azole drugs are the frontline treatment against fungal infections however resistance to current azole antifungals in C. albicans poses a threat to public health. Two serie...
