This has been discussed many times on the mouse forums. New people come on and think that adding in wild mice will help with genetic diseases or make stronger mice.
But it's simply un-true. Like Dr.Del said, a LOT (as in 300+ years) has been put into domesticating mice, and breeding them for show, breeding them for pets, and breeding them to have large litters for feeders. Adding in wild mice would just add in un-knowns, and set back all that hard work.
Also, any mice with wild genes in them, tend to be extremely skittish, flighty, and bitey. It just ruins domestication.
Also, antibiotics will not kill parasites.
