Lyme Disease and Our Blue Belly Hero

Lizardcave.jpg

The bacterium Borrelia burgdorfii, causes Lyme disease which is transmitted 
to the blood of a host by a biting tick.

The Western United States has just a many potential Lyme disease-bearing ticks as the Eastern United States. Why then is 
Lyme disease 400 times more common in Connecticut than California? They don’t have Sceloporus occidentalis, the Western 
Fence Lizard, also known as Blue Bellies.

A component of the Blue Belly blood has a bactericidal factor that destroys the Lyme disease-causing bacteria in ticks. 
The lizards pickup the ticks in their nymphal stages, lying among the leaf litter. Tick nymphs that have their fill of 
Blue Belly blood become adults that do not carry the Lyme disease bacteria.
