Antibiotics are not the ultimate cure, as they are only effective during specific phases of Lyme disease proliferation. Borrelia bacteria can enter dormant phases during which antibiotics are ineffective. Under the influence of antibiotics, they sometimes form cell wall-deficient forms that the immune system no longer recognizes. Furthermore, antibiotics disrupt the horse's gut flora, which plays a crucial role in the body's defense. This often leads to fungal infections, allergic reactions, and, in rare cases, anaphylactic shock. Infections that previously appeared to be cured can recur.
Substances that repel ticks can be a good start, but they don't offer complete protection. Therefore, horses should be regularly checked for ticks. Use only appropriate tools to remove the parasites. Oil, glue, or fire should not be used. The tick should be removed whole, including the head, without squeezing it, to avoid infection. Another approach to preventing Lyme disease is to support the immune system. For example, up to 20% of Germans have antibodies against Borrelia bacteria without ever showing symptoms of the disease. This means that even if an infection occurs through a tick bite, not every infected person automatically develops the dangerous Lyme disease. Therefore, it is important to strengthen the immune system to prevent the disease.
