Tick-borne infections of dogs in Serbia: a review of research

Abstract

Increased prevalence of tick-borne disease in humans and animals is an important public health issue. Dogs can be clinically ill, reservoirs of tick-borne pathogens, or sentinel populations for research. Certainly, small-scale research has been conducted in dogs and this review will focus on the recent studies of emergent and re-emergent tick-borne pathogens in dogs in Serbia. Babesiosis stands out as the most common and important tick-borne disease in dogs. In addition to this pathogen, the presence of Hepatozoon canis and “Candidatus Mycoplasma haematoparvum” in the blood of dogs was proved using molecular methods. Seroreactivity in dogs has been proven for Borrelia burgdorferi sensu lato (s.l.) complex, Ehrlichia canis, Ehrlichia ewingii, Anaplasma phagocytophilum, Anaplasma platys, Rickettsia conorii, and tick-borne encephalitis virus (TBEV). The presence of B. burgdorferi s.l. complex, A. phagocytophilum, Rickettsia spp. from the group of spotted fevers, and TBEV in ticks indicates the geographical distribution and potential for infecting humans, dogs, and other animals in Serbia. Further systematic, comprehensive, well designed, bacteriological, virological, parasitological, epidemiological, clinical (infectological), and acarological research is needed in Serbia.
