  • Spirochaete bacteria of the Borrelia burgdorferi sensu lato complex. Long and slender organism that is helical coiled (0.2-0.5 µm x 8-30 µm)

    In Europe three species, Borrelia burgdorferi sensu stricto, Borrelia garinii, Borrelia afzelii.

  • Ixodes ricinus is the vector involved in transmitting Borrelia. Larvae, nymphs and adults can transmit the bacteria.

    Learn more about the vectors: Ticks

  • The infection can be found in humans, cattle, horses and dogs in most European countries. Around 15% of all ticks harbour Borrelia DNA (the percentage varies according to the region).

  • General signs: high temperature, asthenia, anorexia and sometimes vomiting and adenopathies.

    Limp: Poly- or monoarthritis in the joints. This sign regresses on average four days before reappearing in another joint in 30 -50% of all cases. Chronic, subclinical periarthritis may develop after several recurrences.

  • Evidence of an exposure to Borrelia burgdorferi (tick bite, endemic/enzootic area)

    Compatible clinical symptoms

    Positive Indirect ImmonuFluorescence test confirmed by Western Blot

    Elimination of other vector-borne infections

    Response to treatment is the final confirmation of diagnosis.

    Differential

    Other vector-borne disease: canine ehrlichiosis, anaplasmosis

    Immunological, neoplastic or degenerative causes

  • The antibiotics most frequently used against canine borreliosis are:

    - Tetracyclines: doxycycline (10 mg/kg per day)

    - β-Lactamines: amoxicillin, penicillin.

    Treatment is necessarily long: up to 30 days of medication to reach the Borrelia embedded deep in the fibrous tissues. There can be no certainty that the infection has been cured.

  • Medical: vaccines

    Sanitary: limit the risk of transmission by vectors by using acaricides to eliminate infestation in dogs

  • Cats are not known to develop signs under normal conditions.

Learn more about parasites

The threat of arthropod parasites for human and animal health is increasingly recognized world wide. The hazard of these insects or acarids is linked to both the direct lesions

they generate as well as their ability to transmit diseases.

How does the model work ?

FleaTickRisk is a unique and dynamic model encompassing an ongoing collaboration between researchers. The maps generated allow visualisation of the risk of infestation by ticks and fleas.
