Diverse Lineages of Live on Old Oaks.

The human pathogen is considered an obligate commensal of animals, yet it is occasionally isolated from trees, shrubs, and grass. We generated genome sequence data for three strains of that we isolated from oak trees in an ancient wood pasture, and compared these to the genomes of over 200 clinical strains. strains from oak are similar to clinical in that they are predominantly diploid and can become homozygous at the mating locus through whole-chromosome loss of heterozygosity.
