Probiotics, the bacteria associated with yogurt, can help control C. diff.

Antibiotics often aren’t enough to combat Clostridium difficile. But when combined with probiotics, or “good” bacteria, the results are striking. The treatment combo lessens the likelihood of  C. diff symptoms by 64%, according to a recent study.

“The introduction of some probiotic regimens as adjuncts to antibiotics could have an immediate impact on patient outcomes, especially in outbreak settings,” said lead researcher Bradley Johnston of The Hospital for Sick Children Research Institute in Toronto.

The Cochrane Collaboration analyzed 23 trials involving more than 4,000 people to reach its conclusion.
