I came across this 2014 article at the National Geographic website which discusses how a biologist and his graduate student at MIT tracked the constituents of their microbiomes every day for a year.
In the student's case, his microbiome was temporarily altered when he visited Bangkok and suffered a couple of bouts of diarrhea. Meanwhile, his professor's microbiome was permanently altered by a salmonella-based episode of food poisoning.
Below is the professor's year long chart. The salmonella-based food poisoning event occurs at about day 150. The upper portion shows the relative proportion of the dominant species. The lower section shows changes in each species, with drops in blue and increases in red.
The article summarizes this paper in Genome Biology.

I found this article when I went looking for information on food poisoning and the microbiome. Eighteen months prior to the onset of ME/CFS, I had an exceptionally acute case of food poisoning. It knocked me off my feet for days and nearly sent me to the ER. Due to the recent interest in the microbiome, I've come to wonder if this event could have somehow "set me up" for ME.
I'm curious if anyone else can recall coming down with severe food poisoning or any other acute, but transitory, gastrointestinal illness within a couple of years prior to coming down with ME.
[Of course, since such illness is not wildly uncommon, the significance of such accounts would be hard to appraise unless it was very common among ME patients.]

It appears that [the student's] microbiome switched from one state to another on his trip, and then back again. [The professor's] microbes had a different experience. His food poisoning disrupted his microbiome, allowing a different combination of species to become dominant. It pushed him into a different state–a healthy one–and he’s now stuck there.
