There is an article on foxnews about a recent breakthrough in the treatment of C-dff (common in elderly patients in hospital or nursing home settings). It is notoriously hard to treat due to it's resistance to antibiotics. It seems that researchers have discovered 7 virus strains that specifically target C-diff bacteria and destroy them, while leaving other bacteria, like the good intestinal bacteria, alone. The virus is administered in a pill. I hope this quickly gets approved for use!
