Project description:Azole resistance was induced in vitro by growth of a susceptible C. parapsilosis isolate in the presence of posaconazole. Whole genome microarrays were used to compare the transcriptional response of the posaconazole-resistant and susceptible isolates.

Loss of sterol demethylase activity reduces both azole and echinocandin antifungal susceptibility in a clinical isolate of C. parapsilosis

Project description:The present study describes a novel mechanism of antifungal resistance affecting the susceptibility of both the azole and echinocandin antifungals in an azole-resistant isolate from a matched pair of C. parapsilosis isolates obtained from a patient with prosthetic valve endocarditis. Transcriptome analysis indicated differential expression of several genes in the resistant isolate including upregulation of ERG1, ERG2, ERG5, ERG6, ERG11, ERG24, ERG25, ERG27, DAP1 and UPC2, of the ergosterol biosynthesis pathway. Whole genome sequencing revealed a mutation in the ERG3 gene leading to a G111R amino acid substitution in the resistant isolate. Subsequent introduction of this allele in the native ERG3 locus in the susceptible isolate resulted in a fluconazole MIC of >64 mg/ml and a caspofungin MIC of 8 mg/ml. Corresponding allelic replacement of the wildtype allele for the mutant allele in the resistant isolate resulted in a drop in MIC to 1 mg/ml for both fluconazole and caspofungin. Sterol profiles indicated a loss of sterol demethylase activity as a result of this mutation. This work demonstrate that this G111R mutation is wholly responsible for the resistant phenotype in the C. parapsilosis resistant isolate and is the first report of this multidrug resistance mechanism.

Proteogenomic of Blastocystis sp. subtype 4 isolate WR1

Project description:description Blastocystis sp. is a highly prevalent anaerobic eukaryotic parasite of humans and animals. The genome of several representatives has been sequenced revealing specific traits such as an intriguing 3’-end processing of primary transcripts. We have acquired a first high-throughput proteomics dataset on the difficult to cultivate ST4 isolate WR1 and detected 2,761 proteins. We evidenced for the first time by proteogenomics a functional termination codon derived from transcript polyadenylation for seven different key cellular components.

A three-dimensional chromatin contact map of Puccinia graminis f.sp. tritici

Project description:Puccinia graminis f.sp. tritici (Pgt), the causal agent of stem rust disease in wheat, is one of the most destructive pathogens and can cause severe yield losses. Here, we utilize Hi-C sequencing technology to scaffold and phase the haplotypes for the genome assembly of a US Pgt isolate 99KS76A-1.

Transcriptional response of an azole-resistant Candida parapsilosis isolate [voriconazole].

Project description:Azole resistance was induced in vitro by growth of a susceptible C. parapsilosis isolate in the presence of voriconazole. Whole genome microarrays were used to compare the transcriptional response of the voriconizole-resistant and susceptible isolates. Transcriptional profile of an in vitro derived voriconazole-resistant isolate of C. parapsilosis (BC014VRC) compared to the susceptible isolate (BC014S). Cell were grown in YPD medium in normoxia at 35 degrees. Each strain was labelled with Cy3 or Cy5. Overall, 4 independent biological replicates were compared; 2 dye swaps were performed to normalize dye effects.
