Lyme Disease might be 15 million years old

Recently studies of ticks fossilized in amber have revealed spirochetes, the bacteria that cause Lyme disease, were being carried by the ticks between 15-20 million years ago. This suggests that Lyme disease might be older than the human race. In studying four ticks preserved in amber, large populations of a spirochete-like species that closely resemble that of the spirochete species that causes Lyme disease today were found. In a similar study, bacteria that resembled the present day bacteria that causes Rocky Mountain Spotted Fever was also observed.
