Scientists uncovered viruses that infect bacteria, called bacteriophages, in animal poop and are testing whether they could work as antibiotics.
Viruses scooped from the poop of giraffes, lemurs and long-whiskered mammals called binturongs could be useful for killing drug-resistant bacteria and preventing further antibiotic resistance, scientists say.
Why go digging for phages in animal poop? Phages are the key ingredient in an emerging treatment for bacterial infections, known as phage therapy. In clinical trials and extreme cases where other treatments have failed, doctors have used phages as an alternative or a supplement to traditional antibiotics. Phages typically kill disease-causing bacteria by invading the germs' cells and slicing them open from the inside.
Stafford and his colleagues are aiming to discover new phages in the environment — and yes, in animal dung — to add to the variety of phages that can be used in treatments."They tend to target only certain species, or even certain strains, so the more that we've got … then the more chance we've got of taking this therapy to a point where we can cover as many bases as possible," he told Live Science.
