L Lyme Disease in humans is caused by infection with a spirochete bacterium. The spirochete is transmitted from mammal to mammal by the deer tick. Scientists discovered that heavy ("mast") acorn production, which occurs every two to six years in oak forests, sets off an ecological chain reaction that regulates Lyme disease. Heavy crops of acorns attract deer to oak forests in autumn. Deer are the preferred host for the adult deer ticks, which lurk in vegetation, waiting to attach to a passing deer so they can take a blood meal. While on the deer, the ticks mate, then eggs drop off. White-footed mice are the favorite hosts of first-year tick larvae. Ticks become infected with the bacterium when they feed on infected animals. Deer are immune to infection by the bacterium, but support tick populations.
