Prof Juichi YAMAGIWA, Kyoto Prefectural university, has screened and characterized a new species of Bifidobacterium from the excrements of a herd of about 20 Western lowland gorillas in Gabon. Genetic analysis revealed that this species might be phylogenetically older compared to Bifidobacteria species in the human gut.
