Summary. Vector infections of dogs, transmitted by ticks, are found in many regions of Russia. During the last 10-15 years in many European countries as well as in Russia new natural focal infectious diseases associated with ticks – herlichiose and anaplasmose – were registered. Their presence in the Rostov region was confirmed by Russian scientists in 2010. For the diagnosis of infection we have developed a kit for detecting Ehrlichia, Anaplasma and Babesia PCR. For species identification of members of the genus Ehrlichia and Anaplasma used a variant of real-time PCR. Association of ehrlichiose, anaplasmose and babesiose is the most serious in dogs. It was found that in non- pregnant animals severe clinical disease is registered in the form of half of the cases, whereas the animals in the second half of the prenatal period, severe disease is very serious in all diseased animals with pronounced changes in the morphological and biochemical parameters of blood.

Keywords: vector infection, diagnosis of vector infection, canine ehrlichiose, canine anplalsmose, ehrlichiose carrier, canine babesiose, canine piroplasmose, chronic anaplasmose, association of vector infections, canine ehrlichiose in the prenatal period, pathogenesis.
