I have had some success with a probiotic product called "Primal Defense". It contains 14 strains of bacteria and can be purchased on several websites . Just do a search for Primal Defense and pick one. It is made from natural ingredients and it reports to be very agressive agains pathological molds, yeast, fungi, parasites, bacteria, and viruses. It can be purchased in powder and tablet form. ( I recommend the tablets since the powder tastes a little too "earthy" ).
