These are indicative of a strong immune response involving the adrenal/pancreas as well. The burping could be to the dysbiosis but I would suspect due to the protozoa infections. You could try a good probiotic (Jarrow EPS, Dr. Ohirra, Garden of Life SBO) and see if that resolves the burping -but I suspect the protozoa are reponsible for this. Burping or gas is coming from the living organisms that are forgein the body.
B. hominis will put a hurt on you (brain fog, dpression, fatigue) and again these will evoke the adrenal/pancreas response which are there to help your body mount a defense. If you want more detailed info on adrenal support let me know.
