I have aquired a quantity of HBC (Hyperimmune bovine colostrum), and I coincidentally have a friend with a White-lipped Python that is carrying a pretty heavy load of Cryptosporidium. The snake is off feed and has been for some time now. I'm going to do a stomach lavage in the next few days and see if I can get an idea of the concentration of bacteria, then treat with HBC at 7 day intervals for 3 treatments, then do another lavage and check concentrations again. If the snake isn't already too far gone, maybe I can get some good data.
