without much comment on my part, but during WW2 the germans had a problem with fatal diarrhea occurring in their armies in north africa. their doctors noticed that the natives would have the same issue but recover. they followed one man with diarrhea around as he followed a camel. when the camel pooped the man scooped up a handful and ate it, that was the local cure. the germans isolated the bacteria and distributed it to the troops. it is interesting to note that the germans did the same thing during WW1 when only one soldier in a pioneer unit had escaped the diarrhea that had affected all others. at that time the german doctors also isolated E. Coli Nissle 1917 and it remains a RX in germany to this day, sometimes used to treat IBD.
