Hi lineup, long time buddy!
No you're right, but the most pathogenic species will almost always cause immediate pathology, then eventually settle down to equilibrium status if not resolved by the individual's immune system.
It my case, there is a very persistent amoeba and likely other co-infections, and the ongoing pathology results in chronic dysbiosis.
I check stool regularly, with an expert eye (under microscopic examination, phase contrast),
and can detect nothing but dead and partially digested bacteria, especially during increased symptoms.
Two things are going on. The PH levels in my gut are too alkaline, from access enzymatic activity. This results from low stomach activity, and high nitrite\nitrate levels.
Second, the parasite itself produces high enzyme content and is a very potent antibiotic.
So I am a walking talking antibiotic machine!
Problem is, we need an abundance of viable lactobacillus, to maintain healthy digestion, and this requires a lower PH in the upper gut.
I can do this, with probiotics, and detox, but it is never permanent, and cannot destroy the primary parasite.
The parasite itself is very fragile, but the spores give it continuity, and they can modulate their rate of population to offset environmental attack.
My antibodies are useless against the thing, which takes us full circle to my original point.
