Essentially they can get gut bacteria from darned near anywhere -- including, but not limited to, drinking out of a puddle or licking your shoe or some grass.
Now, all those things (stress, etc.) set the gut up to not deal as well with that bacteria -- it can be anything from one incident of something overwhelming to a whole cluster of things all "stressing a bit more" or adding a bit more bacteria.
this is not a cop out ... but seriously sometimes it just "happens". That doesn't sound scientific but it's simply a normal name for a whole chain of events that all conspires against them.
That IS one of the reasons why I tend to have fecals for my dogs far more often than most folks -- 3 of my 4 tend to be immune-suppressed so they can be sitting targets. *sigh*
