Lyme disease in horses

Three new papers on Lyme Disease provide interesting information but do little to clarify this complex and frustrating disease. All three have free links to the actual paper if you are interested in getting down into the weeds.

The first shows that dog Lyme vaccines do a poor job of inducing a protective immune response in the horse.

The second shows that in a nearby area, Blacksburg, VA, about a third of normal horses have a positive titer to Lyme and that those titers are unlikely to change over a year's time.

Rarely Borrelia, the causitive agent in Lyme disease can cause neurologic disease.  Even when confirmed histologically at postmortem, blood and csf tests were not always reliable diagnostics.
