Lyme disease descibes the clinical syndrome caused by infection with ''[[Borrelia burgdorferi]]'' sensu lato in humans, dogs, horses, cattle and sheep.  The disease is named after the town of [http://townlyme.org/ Lyme] in Connecticut, USA where clinical cases were first described in humans in 1975.  Since its identification, analysis of historical samples of ticks has shown that ''B. burgdorferi'' has been present in Europe and North America since at least the start of the twentieth Century<ref>Marshall WF 3rd, Telford SR 3rd, Rys PN, Rutledge BJ, Mathiesen D, Malawista SE, Spielman A, Persing DH.

==Prognosis==

Prognostication is difficult as the clinical presentation varies so widely between animals.  With the exception of those animals with Lyme nephritis, the response to treatment is generally good, even if the bacteria are eliminated.
