The Were's in the book I'm trying to sell have two rather specific differences in their blood. Scott Gardener touched on it when he said
"Unknown something in the blood in large numbers".
My Were's have extra Red Blood cells stored in their Spleen (like a horse), and exertion will draw them out. THe other "somethings" look like White Cells; Leucocytes, but they aren't: They are Type-R cells (sort of a hyper stem cell) that accounts for the healing capability, and Type-I cells, which do the following: Act as a sort of "Super White Cell"-or Macrophage. In the case of Poisoning or Infection, they do the White cell thing and surround the harm-causing matter and get flushed out with the Urine. Unlike White Cells, they don't die after they do this, but rather release a trigger-chemical that "calls' other Type-I cells to congregate in the area, looking for other "not body" substances.
The Red Cells are slightly different, too; in that they are not the normal Disk shaped cells in unmutated Humans, but are instead, shaped like a figure "eight" and flatter than Non-mutated RBC's, carrying more Oxygen and being able to fit two into a capillary that would accomodate only a single non-mutated RBC.
There are also cysted-over Viroids: new Werewolves waiting for a new host to convert. They are literally all over the place, and you'll find them in just about every bodily structure and fluid: even the Reproductive fluids and cells are loaded with them, and if they wind up in a body that doesn't have the trigger that makes them go cystic, they become active and invade their new host; making it stronger, healthier, more robust, and just a bit Fuzzy and Toothy.
This is their Survival strategy: Community Improvement. The Werewolf is just a side effect.
