Escherichia coli Nissle 1917 is a strain of Escherichia coli that was isolated from the feces of a German soldier in 1917 by the German researcher Alfred Nissle. Since that time it has been widely studied as a probiotic and several marketed probiotics include it and naturally colonizes the human intestines and has positive probiotic properties. [1] Only 50 to 80% of patients who take it daily have detectable amounts in their feces. The precise reason is unknown. It is known that the F1C fimbriae are important for colonization. [2]
