I just looked at the article and I'm glad to see them looking into this theory.
I have no idea what the virus or bacteria would have been, but both my husband and I got very sick in 1985 exactly a week after we got home from a trip to Cancun. I had numerous stool samples which never showed anything. Our d gradually improved, his more quickly than mine. I believe that a year or two after that I was diagnosed with IBS, which seems to have flared off and on over the years.
But I still wonder if I first got some virus, bacteria or parasite that was the beginning of this DD.
