Lizards Save California from Lyme Disease

A recent report by the Centers for Disease Control concludes that Lyme Disease is vastly more common than previously supposed. Yet, in California, Lyme Disease levels remain very low, despite large deer populations. California’s detox secret is the humble Western Fence Lizard, which picks up the bacteria from tics and kills the germ before it can spread:

The CDC report might lead health authorities to accelerate the research and approval of a Lyme vaccine. Promising results were found earlier this year on one vaccine under development. That would be a popular item in prime Lyme disease territory, largely the Northeast and northern Midwest states where up to 30% of deer ticks carry the infection. Almost all cases of the disease — 96% – occur in 13 states.

California isn’t among them, and one reason for that is that we have, in a sense, our own little natural vaccine program going. In this state, nymphal ticks’ favorite host is the common western fence lizard, which has a protein in it blood that kills the bacterium responsible for Lyme. As a result, few adult ticks are carriers. [LAT]

Three cheers for the Western Fence Lizard!
