Interaction of soil amoeba Protostelium aurantium with three pathogenic yeasts Candida spp. (here: C. albicans and C. glabrata)

Project description:We investigated different escape and defense strategies of Candida glabrata and Candida albicans against the natural fungivorous predator Protostelium aurantium using dual RNA-Seq. While C. albicans was found to be very succesfull in preventing from amoeba recognition, C. glabrata in turn, was rapidly taken up but remained undigested with a comparably low transcriptional activity. Trophozoites of the amoeba Protostelium aurantium were fed seperately with the two fungal species and samples for RNA isolation were taken at time points 0 min (control), 30 min and 60 min. At indicated time points samples were shock frozen and used for RNA isolation. Samples for RNAseq were taken at time points 0 min (control), 30 min and 60 min. RNA samples from identical timepoints for C. albicans and C. glabrata were pooled for RNA sequencing. We investigated different escape and defense strategies of Candida spp. against natural fungivorous predator. While C. parapsilosis underwent rapid predation and intracellular killing of the yeast, C. albicans was found to be very succesfull in preventing from amoeba recognition. C. glabrata in turn, was rapidly taken up but remained undigested with a comparably low transcriptional activity.

Limosilactobacillus fermentum Limits Candida glabrata Growth by Ergosterol Depletion

Project description:Candida glabrata is a human-associated opportunistic fungal pathogen. It shares its niche with Lactobacillus spp. in the gastrointestinal and vaginal tract. In fact, Lactobacillus species are thought to competitively prevent Candida overgrowth. We investigated the molecular aspects of this antifungal effect by analyzing the interaction of C. glabrata strains with Limosilactobacillus fermentum. From a collection of clinical C. glabrata isolates, we identified strains with different sensitivities to L. fermentum in coculture. We analyzed the variation of their expression pattern to isolate the specific response to L. fermentum. C. glabrata-L. fermentum coculture induced genes associated with ergosterol biosynthesis, weak acid stress, and drug/chemical stress. L. fermentum coculture depleted C. glabrata ergosterol. The reduction of ergosterol was dependent on the Lactobacillus species, even in coculture with different Candida species. We found a similar ergosterol-depleting effect with other lactobacillus strains (Lactobacillus crispatus and Lactobacillus rhamosus) on Candida albicans, Candida tropicalis, and Candida krusei. The addition of ergosterol improved C. glabrata growth in the coculture. Blocking ergosterol synthesis with fluconazole increased the susceptibility against L. fermentum, which was again mitigated by the addition of ergosterol. In accordance, a C. glabrata Derg11 mutant, defective in ergosterol biosynthesis, was highly sensitive to L. fermentum. In conclusion, our analysis indicates an unexpected direct function of ergosterol for C. glabrata proliferation in coculture with L. fermentum.
