+Lyme disease is caused by the bacteria //Borrelia burgdorferi// and can be transmitted to humans trough the bites of ticks. It is an important public health issue in the US, where it is the most common vector-borne disease.  Other vertebrate hosts can be infected and act as reservoirs.  Host species differ in their **host competence**, which is the ability to sustain the population of ticks.  There is also variation among species in the **reservoir competence**, which is the ability of an infected host to infect a tick.

+The lizard //Sceloporus occidentalis// is by far the most competent host of the tick //Ixodes pacificus// in the western US. Nevertheless, the lizard has a very low reservoir competence, as it has highly effective immune defenses against //Borrelia burgdorferi//. Therefore, //S. occidentalis// can act as an important barrier to the transmission of Lyme disease in the region. Oddly enough, an experimental removal of lizards did not increase the tick infection prevalence, nor was there a marked increase in the tick load on alternative hosts ((Andrea Swei, Richard S.
