Deer in more than a dozen California counties are infested with a type of louse that normally affects deer in Asia and Europe, according to wildlife authorities. Blood and hair samples from some 600 deer and elk with hair loss have been tested since 2009, confirming the presence of the lice. "What we do know is that the louse has impacted migratory populations of California deer, which now have a low fawn survival rate, making it difficult to replenish the herd," said senior wildlife biologist Greg Gerstenberg of the state Department of Fish and Wildlife.
