My grandmother is the only human ever to contract Swine Earisyphillus (SP??). She turned purple (as purple as the girl in Willy Wonka).
She worked in a pharmacutcial labratory, giving the disease of the week to rats. One day, someone distracted her as she was giving the injection of this pig disease, and accidently shot herself.
So, off to the hospital they go. The veternarians were called, and she told them the treatment procedures they had tried, and together they got her back to normal - no longer purple! Too bad, my grandkids would have loved to see that.
She also worked on cancer treatment drugs. I have a pic of her in the lab, all those beaker tubes, holding a clipboard, in her lab coat. I love that pic.
And though I never saw her at work, it typifies to me what kind of woman she was, as she had to raise her 3 girls all alone when her husband died when Mom was just a year old. It was during WW1 and there really wasn't much for a single lady to do.
