Canine leishmaniosis: An update regarding diagnostics, therapeutic approaches, and monitoring

Abstract

Canine infections with Leishmania (L.) infantum are gaining significance in Germany due to rising numbers of dogs imported from endemic countries, frequent travel and changing of climatic conditions in Central Europe. Dogs without any clinical signs suspicious for vector-borne infections imported from other countries to Germany should be tested immediately after import and 6 months later. In dogs with clinical signs suspicious for leishmaniosis, direct and indirect detection methods of the pathogen as well as hematology, biochemistry, serum protein electrophoresis and C-reactive protein are recommended. For treatment and monitoring of canine leishmaniosis, the LeishVet-guidelines are highly recommended. Different therapeutic options include first-line, second-line, and third-line drugs. For dose adjustments of allopurinol, the step plan should be taken in consideration. Due to climatic changes, habitats of sandflies as transmitting vectors of leishmaniosis are expanding. Next to vectorial transmission mating, transplacental infections, bite wounds, and blood transfusions were described in canine leishmaniosis. Additionally, L. infantum is a zoonotic vector-borne infectious pathogen, which is important regarding the One-health-aspect.
