Anaplasmosis is the most common tick-transferred disease to cause illness in horses. Humans and other animal species, including dogs and livestock can get a similar illness from ticks. Deer ticks commonly transfer the bacteria from small mammals (deer mice and woodrats). In horses, signs of illness usually appear 10 to 45 days after infection.

Lyme disease is the most common vector-borne disease in the United States. Lyme disease is caused by the bacterium Borrelia burgdorferi and rarely, Borrelia mayonii, which is transmitted by the bite of infected ticks. On the east coast of the United States, the tick vector is Ixodes scapularis, whereas on the Pacific coast, Ixodes pacificusvectors ...
There are close to 30,000 human cases reported to the Centers for Disease Control (CDC) annually. Nonetheless, two different studies estimated that the number of human cases in the United States is around 300,000 per year. Lyme disease cases are typically concentrated in the Northeast and upper Midwest, with 14 states accounting for over 96% of cas...
In New Jersey, Lyme disease is spread by the bite of either nymphs or adults of Ixodes scapularis, also known as the deer tick or blacklegged tick. Nymphs are present from early spring until the early summer, while adults are generally found during the fall. Thus, spring and fall are the times that horses are at greatest risk of exposure to Lyme di...
No, only deer ticks (I. scapularis) can transmit Lyme disease in New Jersey. Other ticks in New Jersey bite and transmit other diseases to humans and animals.
The range of specific clinical signs associated with Lyme disease in horses is not well established. The best documented syndromes associated with Lyme disease include neuroborreliosis, uveitis, and cutaneous pseudolymphoma. Other associations that are plausible but not well documented include stiffness, intermittent or shifting-limb lameness, poor...
Most horses that are seropositive to B. burgdorferinever showed symptoms of Lyme disease or were so mild that they were not diagnosed. The best characterized signs of Lyme disease are neuroborreliosis and uveitis, which are compatible with late dissemination signs that in humans generally occur months to years after the initial infection.
If clinical signs correspond to Lyme disease, your veterinarian may do a quick in-house assay to check for antibodies against one of the B. burgdorferiproteins. However, this method does not quantify the number of antibodies the animal is producing. A more comprehensive test that can follow up the course of infection is available through Cornell Un...
Treatment for Lyme disease in horses is based on human treatments and single treatment trials in experimentally-infected ponies. In Lyme endemic areas, most practitioners treat horses with clinical signs and a confirmed serological antibody titer to B. burgdorferiwith antibiotics like tetracyclines and β‐lactam drugs. Some practitioners, based on c...
Ticks found on a horse should be removed as soon as possible using a plain set of fine-tipped tweezers. However, the horse must be properly restrained by an assistant for the safety of the person removing the tick. 1. Use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible. 2. Pull outward with steady, even pressure. D...
Anaplasmosis is another common disease that can be transmitted via ticks to horses (equine anaplasmosis), humans (human anaplasmosis), and other animals. The causative organism, Anaplasma phagocytophilum, is a Gram-negative bacterium (formerly known as Ehrlichia equi, hence the persistent older disease name, equine ehrlichiosis), that deer ticks co...
May 20, 2021 · The signs can be vague and mysterious. A thumbnail-size lump on the body, general lethargy and sore joints could point to anything or nothing at all, which is exactly the problem posed by Lyme disease in horses, which can present as a number of rather generic symptoms.
