WIth new Werewolf DLC I thouhght it would be appropriate to bring this up. Since this is a racial thing, might we even see one for each beast race?
Those are different strains. If a werewolf bites any race they still transform into a werewolf. If a werecrocodile bites any race then and only then would they transform into a werecrocodile. An Argonian won't suddenly become a werecrocodile if a werewolf bites him just because the argonians look reptilian
