Urban animals may get some dangerous gut microbes from humans
Animals moving into the big city could be getting more than they bargained for. Gut microorganisms from humans in cities may be spilling over into urban wildlife, potentially putting the…
A disinfectant made from sawdust mows down deadly microbes
A new, sustainable disinfectant made from sawdust and water can knock out more than 99 percent of some disease-causing microbes, including anthrax and several strains of flu. Widespread use of…
Drug-resistant bacteria evolved on hedgehogs long before the use of antibiotics
Beneath the prickly spines of European hedgehogs, a microbial standoff may have bred a dangerous drug-resistant pathogen long before the era of antibiotic use in humans. It’s no question that…
A bacteria-virus arms race could lead to a new way to treat shigellosis
When some bacteria manage to escape being killed by a virus, the microbes end up hamstringing themselves. And that could be useful in the fight to treat infections. The bacterium…
Gut bacteria let vulture bees eat rotting flesh without getting sick
