RESUMO
Here, we report draft genome sequences of Bacillus pseudomycoides SC107, Rossellomorea sp. SC111, Peribacillus frigoritolerans SC112, Priestia megaterium SC114, Paenibacillus sp. SC116, and Lysinibacillus fusiformis SC117, isolated from a campus wooded area in Loudonville, NY. Genomes were sequenced using the Illumina NextSeq system. The genomes range between 4,381,526 and 6,065,181 bp with GC contents between 35.33% and 43.46%.
RESUMO
Candida albicans is a commensal of the urogenital tract and the predominant cause of vulvovaginal candidiasis (VVC). Factors that increase circulatory estrogen levels such as pregnancy, the use of oral contraceptives, and hormone replacement therapy predispose women to VVC, but the reasons for this are largely unknown. Here, we investigate how adaptation of C. albicans to estrogen impacts the fungal host-pathogen interaction. Estrogen promotes fungal virulence by enabling C. albicans to avoid the actions of the innate immune system. Estrogen-induced innate immune evasion is mediated via inhibition of opsonophagocytosis through enhanced acquisition of the human complement regulatory protein, Factor H, on the fungal cell surface. Estrogen-induced accumulation of Factor H is dependent on the fungal cell surface protein Gpd2. The discovery of this hormone-sensing pathway might pave the way in explaining gender biases associated with fungal infections and may provide an alternative approach to improving women's health.
