The fungus that some dogs carry in their nose evolves within the dog's nose. The genetic changes indicate adaptation of the fungus to the dog. That's also of importance for humans, since infection with this fungus can be deadly. Researchers of Utrecht University gained these new insights in research on natural infections of dogs that came with an inflammation at the veterinarian. The study thus also shows that studying natural infections is an alternative to experiments with laboratory animals. They publish their findings 12 November in Nature Biofilms and Microbiomes.
