re: My Lab May Die Due to Fungus (pics posted) (Updated 9-22-2016)

Glass notes that a serologic survey of hunting and retrieving dogs from at-risk areas showed that 15 to 20 percent of these animals have antibodies to Pythium, indicating previous exposure and successful destruction of the fungus. While no such serologic survey has been done in horses, Glass suspects similar findings, noting that it is "just not that easy for all horses to become infected with Pythium species since many more horses are exposed than become ill, and all the factors required for successful infection are not yet known."
