Project description:Candida auris reference strain B11221 was spread on YPD plate supplemented with 8 μg/ml tunicamycin. Randomly 25 adaptors (T2080-T2104) were chosen. These adaptors and the parent were sequenced.
Project description:Creation of a new library entries for Candida auris using MALDI Biotyper. Candida auris has a high genetic variability in the world, the identification of Colombian isolates is difficult using the main Bruker library. A new in-house library was created using Colombian isolated and was validated using 300 isolated strains
Project description:Candida auris occupies similar niches in various infections as Pseudomonas aeruginosa; however, the details of their interspecies communication remain largely unknown. To gain deeper insights into this bacterial–fungal relationship, phenotypic and transcriptomic analyses were conducted in the presence of the primary P. aeruginosa quorum-sensing molecule, 3-oxo-C12-homoserine lactone (HSL), against C. auris, with the results compared to those of C. albicans. We demonstrated a significant HSL-induced reduction in adhesion of C. auris cells at 100- and 200-μM concentrations. Furthermore, HSL exposure reduced intracellular iron and zinc levels and modulated C. auris metabolism toward beta-oxidation, which may be associated with the observed reduction in in vivo virulence at lower HSL concentrations compared with C. albicans. RNA-sequencing transcriptome analysis revealed 67 and 306 upregulated genes, as well as 111 and 168 downregulated genes, in response to 100 and 200 μM HSL, respectively. We identified 45 overlapping upregulated and 25 overlapping downregulated genes between the two HSL concentrations. Our findings indicate that HSL-induced effects are not specific to C. albicans; additionally, several characteristics are present in C. auris but not in C. albicans following HSL exposure. Similar to other Candida-derived C12 compounds (e.g., farnesol), HSL reduces several C. auris survival strategies, which may significantly influence the nature of P. aeruginosa–C. auris co-habitation.
Project description:This study aimed to characterise the transcriptional response of two strains of Candida auris (UACa11 and UACa20) during media-induced aggregation due to differences in phenotype. RNA was isolated from each strain under both aggregating and non-aggregating culture conditions.
Project description:Candida auris clade III isolate B12039 was spread on YPD plate supplemented with 128 µg/ml fluconazole. Randomly 39 adaptors were chosen for further analysis. We did sequencing of them as as well as the parent.
Project description:Candida auris clade III isolate B11221 was spread on YPD plate supplemented with 8 µg/ml tunicamycin. Randomly 18 adaptors were chosen for further analysis. We did sequencing of these 18 adaptors as well as the parent.
Project description:Candida auris clade III isolate B12039 was spread on YPD plate supplemented with 8 µg/ml tunicamycin. Randomly 27 adaptors were chosen for further analysis. We did sequencing of these 27 adaptors as well as the parent.
