New Lyme Disease Test for Dogs

New test offers earlier diagnosis – and can identify the stage of the dog’s infection.

Researchers at Cornell University’s Animal Health Diagnostic Center have developed a new test for Lyme disease in dogs. Available as of June 15, the Lyme multiplex assay is capable of distinguishing between infection and vaccination when vaccination history is available, and between early and chronic disease stages, from a single blood sample. Borrelia burgdorferi, the bacteria that cause Lyme disease, migrate by way of the tissues to the joints, nervous system, and organs, causing fever, pain, lameness, and sometimes kidney failure (Lyme nephropathy). By the time these clinical signs show up, the infection may have been present 6 to 8 weeks or longer.
