An experimental compound has been shown to effectively fight Clostridium difficile in lab mice.

The compound mimics a natural cellular defense mechanism that neutralizes the toxins that cause C. difficile. In laboratory studies, mice treated with the compound became less ill and were more likely to survive C. diff infection than untreated mice.

“This may prove to be an alternative to antibiotics,” study author Tor Savidge, M.D., told Reuters. He added that more study is needed.

Full findings were published in the journal Nature Medicine.
