If the animal is showing clinical signs associated with Lyme disease, in many cases the outer-surface protein F will be elevated, but not always. “If one of these areas, particularly the outer-surface protein F, is positive, it doesn’t mean it’s causing disease in the horse it simply means the animal has been exposed. “What is considered positive is a little hard to specifically define,” notes Mittel. These results leave room for interpretation. “Outer surface protein F” antibodies in horses with chronic infection, identifiable from two to three months on.“Outer surface protein C” antibodies in recently infected horses, which are present within three to five weeks of infection, declining by seven to 11 weeks and no longer present by five months and.“Outer surface protein A” antibodies, which were previously thought to be found in vaccinated horses, but now the research is undecided.This screening identifies three antigen proteins: burgdorferiantibodies (the immune system produces antibodies to fight antigens, or foreign substances, it detects) in the blood is the equine Lyme Multiplex assay developed by the Animal Health Diagnostic Center. Researchers have made strides in Lyme disease diagnostic testing, but there’s still a long way to go. While Lyme disease symptoms are not necessarily cut-and-dried, they can include low-grade fever, muscle tenderness, muscle wasting, weight loss, a stiff or uncoordinated gait, swollen joints, “shifting” lameness in various joints, lethargy, hyperesthesia (sensitivity to sound and touch), and uveitis (simply, inflammation of the vascular layer of the eye). burgdorferi infects the horse’s nervous system. Lyme neuroborreliosis (NB), a rare condition, occurs when B. Some signs might arise from the bacterial infection itself, while others (e.g., uveitis) result from the body’s immune response to it. While in private practice in the Northeast, Mittel often saw non-neurologic clinical signs of Lyme disease that included unexplained weight loss, changes in attitude and behavior, uveitis, and hypersensitivity. So while Lyme disease symptoms are not necessarily cut-and-dried, they can include low-grade fever, muscle tenderness, muscle wasting, weight loss, a stiff or uncoordinated gait, swollen joints, “shifting” lameness in various joints, lethargy, hyperesthesia (sensitivity to sound and touch), and uveitis (simply, inflammation of the vascular layer of the eye). An infected tick might or might not transmit the bacteria to its host, and an infected animal might or might not exhibit signs of disease. In short, nothing is straightforward with this disease. Even if you know an infected tick bit your horse (You can actually test it!), signs of Lyme disease might not appear for up to six weeks after exposure. “ Signs of Lyme disease might not appear until 6 weeks after exposure” Diagnosis Here’s why diagnosing Lyme disease is tricky: Not all infected horses exhibit clinical signs, and the signs themselves are often confounding, meaning they can point to any number of other diseases. Horses contract Lyme disease when the spirochete (a type of bacterium) Borrelia burgdorferi is transmitted through the bite of an infected tick. Lyme disease is a very difficult disease to prevent, diagnose, and treat in horses, says Linda Mittel, MSPH, DVM, senior extension associate at Cornell University’s Animal Health Diagnostic Center, in Ithaca, New York. In these regions contracting Lyme disease from infected ticks is entirely possible for horses and humans alike. Horse owners living in areas of the country heavily infested with Ixodes scapularis, commonly known as blacklegged ticks (also referred to as deer ticks or bear ticks), know these parasites are more than a nuisance. In this article we’ll take a look at the three that pose the biggest risk to horses: Lyme disease, anaplasmosis, and piroplasmosis. With Centers for Disease Control and Prevention (CDC) maps outlining tick ranges throughout the majority of the United States, it’s important we brush up on our understanding of tick-borne diseases. That feeling is founded on more than a natural aversion to arachnids diseases transmitted by ticks can pose a real health threat.
