Abstract
BACKGROUND: In recent years, the One Health approach and vector-borne diseases have become an increasingly topical problem around the world. In addition, climate change has a significant impact on zoonoses and public health. We present a case report of tick-borne disease in a dog. CASE DESCRIPTION: A clinical case of Anaplasma platys infection in a 10-year-old female dog (Labrador retriever) is described. Clinical, hematological, biochemical, serological, cytological, and polymerase chain reaction tests supporting the diagnosis have been performed. CONCLUSION: To the best of our knowledge, this is the first report of A. platys from Bulgaria. This report adds to the overall knowledge of Anaplasma spp. in our country and the region of Southeastern Europe.
