i did a search on corona virus and chlorotetracycline. it is heavily manufactured and sold to chinese farmers for additon to animal feed. It amkes no sense biologically to cure a coraonavirus with a tetracycline, but it is sold anyway. this is a great misuse of antibiotics. I was going to tell augie about how the name chow chow came about. I thought he would appreciate it.............., at least vis a vis the market
