Lyme Borreliosis (tick-borne)

Image for the Infectious Diseases category

Equine Lyme borreliosis is transmitted by ticks via bacteria of the Borrelia burgdorferi complex. Many horses carry antibodies without ever falling ill — attributing symptoms to an active borreliosis is diagnostically demanding and professionally disputed. The clinical picture is considered non-specific and is classified neutrally and cautiously.

Veterinary care required

This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.

Priority · vet & management

Since diagnosis is difficult and a positive antibody test alone does not prove active disease, suspected cases belong in careful veterinary clarification with exclusion of other causes; the treatment decision (antibiotic — a prescription medicine) is made solely by the vet. Complementary feeds have no pathogen-effective role.

Possible causes

  • · Borrelia burgdorferi sensu lato (bacterial complex)
  • · transmission via the bite of infected hard ticks (esp. Ixodes ricinus)
  • · higher exposure risk in tick-rich, damp pasture/woodland areas
  • · longer feeding time of the tick raises the transmission risk

Prevention

Consistent tick protection comes first: regular checking after turnout and prompt, complete removal of ticks, care of pasture margins as well as, where appropriate, vet-coordinated repellents lower the transmission risk.

Equiterna's take

Equiterna classifies equine borreliosis deliberately neutrally and cautiously, because diagnostics and disease relevance are professionally disputed — the practically usable lever is tick protection, the assessment of findings remains veterinary.
