LYME BORRELIOSIS IN A DOG

In a 2-year old Bernese Mountain dog the diagnosis of Lyme borreliosis was made, using the criteria that are mentioned in the literature: se ropositivity in the presence of the typical clinical symptoms, with in festation of ticks in the history. The usual therapy of amoxycillin or tetracyclines was inadequate and did not resolve the clinical symptom s, possibly as a result of a combinations of initial corticosteroid th erapy, the clinical presentation of the disease (mainly meningitis), a nd a presumed immuno-incompetence often seen in this breed. Intravenou s treatment with amoxycillin finally led to total cure of the disease. Lyme borreliosis recurrred half a year later, presumably as a result of a new tick infestation. A review of the literature on Lyme borrelio lis in humans and dogs is presented. The fact that Lyme borreliosis in dogs in the Netherlands has not been diagnosed often and has not been reported before may be due to differences in approach to human and ca nine patients with fever.
