Rifabutin= BV100 is a rifamycin antibiotic; one of them is rifampicin, which is still a cornerstone for treating tuberculosis.
So it may be that also the side effects of BV100 are somehow similar to rifamycins and there are many of them if you look at Wikipedia. But all drugs have adverse effects and I would say PBT2 had perhaps less than most of them. Usually, antibiotics are not used for months to avoid side effects. The dog problem may not be so valid when used as an antibiotic when compared to used every day for years in AD, HD, etc.

PBT2 is money to ATH as was told to us already 2 years ago by Kempler. ATH is keen on money as any company, and also QU with the 4 inventors, all want money as do we, investors.
