Details of the tick-borne diseases that travelling pets can acquire in Europe can be found by visiting the parasite maps information on the Travelling Pets page. When ticks feed they can transfer pathogens they are carrying into the animal on which they are feeding. Ixodes ricinus is the most important vector tick in the UK as it transmits the spirochaete, Borrelia burgdorferi sensu lato (Lyme disease), and Anaplasma phagocytophilum (anaplasmosis) and it is the most widespread tick. Transmitted by Ticks (Tick-Borne Diseases - TBDs): Prevention of phlebotome bites by the application of repellents/insecticides to dogs in the form of impregnated collars, sprays and spot-on preparations is currently the most promising strategy for preventing leishmaniosis infection.The main risks in endemic areas are related to vector exposure and abundance of reservoir hosts which include dogs living outdoors, a high stray dog population, dogs adopted from animal shelters in endemic areas and hunting dogs.The incubation period can vary between 2 months and 8 years and is dependent on a number of immunological mechanisms.Vector activity is highest during the night and at a minimum temperature of about 18- 22☌ are highly vector specific and are transmitted by the blood-sucking females of several Phlebotomus species while feeding on their hosts. infantum transmitted by several phlebotome species infantum infection, but cats can also be hosts of L. The dog is considered the main host of L.In Europe, canine leishmaniosis is caused by Leishmania infantum which comprises various enzymatic types (zymodemes).Vector-borne diseases can only be effectively controlled through knowledge of the infectious agents and their vectors.įor more information about VBDs please click the links below. Babesiosis, for example, has been observed across central Europe in the past few years, emerging from previous endemic regions in Europe. Such an expansion of endemic areas has been recorded for various parasitic diseases such as dirofilariosis, babesiosis and leishmaniosis. Rare diseases may increase in frequency in certain areas, either due to increased importation of infected animals or because the causative agents and their vectors spread to and establish in previously non-endemic areas. Several are important zoonoses such as leishmaniosis, borreliosis, rickettsiosis, bartonellosis and dirofilariosisĬlimatic and ecological changes, national regulations on management of stray dogs and cats together with the increase in pet travel and translocation of pet animals can influence the present epidemiological situation of vector-borne diseases in Europe.Animals may have persistent infections and thus act as reservoirs.Variable clinical signs can develop after long incubation periods and these are rarely pathognomonic.Their diagnosis and control are difficult.Their transmission is often unpredictable.They may be highly pathogenic in dogs and cats.
