Just wanted to put my two cents in. I have had these black specks as well in my stool ever since I have gotton over the cdiff. Fortunately I took one bout of Flagl and the symptoms went away but my bowels never ever returned the same. The consistancy is soft to moderatly hard and usually yellowish brown, but never dark brown like they were before. I noticed the black specks too even though I dont have active cdiff. I think I will talk to my MD about these just to make sure. Cdiff has also left me with intolerances to certain foods, esp. combination pizza! Well, also I eat a cup of yogurt and banana everyday. Just wanted to let you know that I think it must be from the diff! What a HORRID bacteria!!
Keep Hoping until it is a REALITY (And it will be!)
