Actually it is a speciman from my husband this morning. I'm not sure what c. difficile infection is. We are currently on Bowtrol. Before that we were on Wormwood Combination for 2 months. The plan now is to wait 90 days and then go on Humaworm. I also submitted this picture to Humaworm Forum and RG@Humaworm said it looks like candida - a yeast overgrowth. Thanks for responding. We are new at all this.
