Emerging vector-borne diseases–incidence through vectors

Vector-borne diseases use to be a major public health concern only in tropical and sub-tropical areas,but today they are an emerging threat for the continental and developed countries also.Nowadays,in intercontinental countries ,there is a struggle with emerging diseases,which have found their way to appear through vectors.Vector-borne zoonotic diseases occur when vectors,animal hosts,climate conditions,pathogens,and suscepti-ble human population exist at the same time,at the same place.Global climate change is predicted to lead to an increase in vector-borne infectious diseases and disease outbreaks.It could affect the range and population of pathogens,host and vectors,transmission sea-son,etc.Reliable surveillance for diseases that are most likely to emerge is required.Canine vector-borne diseases represent a complex group of diseases including anaplas-mosis,babesiosis,bartonellosis,borreliosis,dirofilariosis,ehrlichiosis,andleishmaniosis.Some of these diseases cause serious clinical symptoms in dogs and some of them have a zoonotic potential with an effect to public health.It is expected from veterinarians in coor-dination with medical doctors to play a fundamental role at primarily prevention and then treatment of vector-borne diseases in dogs.The OneHealth concept has to be integrated into the struggle against emerging diseases.During a 4-year period,from2009 to2013,a total number of 551 dog samples were analyzed for vector-borne diseases(borreliosis,babesiosis,ehrlichiosis,anaplasmosis,dirofilariosis,andleishmaniasis ) in routine labora-tory work.The analysis was done by serological tests–ELISA for borreliosis,dirofilariosis,andleishmaniasis,modified Knotttest for dirofilariosis,and blood smear for babesiosis,ehrlichiosis,andanaplasmosis.This number of samples represented 75% of total number of samples that were sent for analysis for different diseases in dogs.Annually,on average more than half of the samples brought to the laboratory to analysis for different infectious diseases are analyzed for vector-borne diseases.In the region of Vojvodina(northern part of Serbia),the following vector-borne infectious diseases have been found in dogs so far :borreliosis,babesiosis,dirofilariosis,leishmaniasis,andanaplasmosis.
