While studying yeast infections in laboratory mice, Steffen Jung and colleagues at the Weizmann Institute discovered that some of their mice carried a novel species of yeast that prevented the animals from being infected with C. albicans.
The new species, which the researchers named Kazachstania weizmannii, is closely related to yeast associated with sourdough production and appears to live innocuously in the intestines of mice, even when the animals are immunosuppressed.
