> In California, adult ticks carry Lyme bacteria less often than nymphs because of a biological quirk in the region. Ticks that carry Lyme bacteria and feed on the western fence lizard lose their infection in the process. The lizard's blood actually clears the infection, said Andrea Swei, who studies ticks and disease transmission at San Francisco State University.
That’s a new one for me. Any idea why the lizard blood cleans out the ticks?
