The new fission yeast species Schizosaccharomyces lindneri is described. The description is based on data derived from phenotypic characterization, genomic sequence and structural analysis, and hybridization trials. Genomic rearrangements most likely played an important role during sympatric speciation. Strains of the new species were isolated from honeybee honey, which seems to be its main habitat. The new species is closely related to Schizosaccharomyces octosporus.

Ninety-seven yeast strains, mostly non-Saccharomyces, were isolated from six species of dung beetles in Botswana's unexplored environments, representing 19 species from 11 genera. An in silico polymerase chain reaction-restriction fragment length polymorphism approach method revealed genetic diversity among isolates of the same species. Potential new yeast species have been discovered.

During infection, Candida albicans employs a variety of virulence factors, that is, release of hydrolytic enzymes, toxins, extracellular vesicles, and quorum-sensing molecules. Furthermore, C. albicans change the morphological form from yeast-like to a more invasive hyphal form. The development of C. albicans infection drives the activation of host immune cells (mainly neutrophils, macrophages, Th17) and strongly stimulates epithelial cells. In later stages of infection, C. albicans form polymicrobial biofilms with a wide range of bacterial species present in the oral cavity.

Tropical forest biomes encompass less than 20% of Earth's terrestrial area, but may contain about 50% of the planet's biodiversity. This review shows that these biomes, mostly situated in regions very vulnerable to deforestation, represent a huge source of new yeast species.
