In recent years, the distribution of Dermacentor reticulatus ticks has expanded into new territories in many European countries, including Poland, with increased population densities in areas of their regular occurrence. The spread of D. reticulatus enhances the risk of exposure of domestic animals and their owners to tick-borne diseases. The objective of this study was to assess the prevalence of infection of D. reticulatus ticks feeding on dogs with the pathogens Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum. The study material comprised 152 D. reticulatus ticks collected from dogs in the northeastern part of Lublin Province (eastern Poland). A ready-made AmpliSens® TBEV, B.burgdorferi sl, A.phagocytophilum, E.chaffeensis/E.muris-FRT PCR kit was used for qualitative detection and differentiation of tick-borne infections. The assessment of the degree of infection of the analyzed ticks with the two pathogens revealed that 9.2% (14/152) of the examined ticks were infected with one of the pathogens. No co-infections with the pathogens were detected in any of the ticks. The highest specific percentage of infections (8.6%, 13/152) was associated with A. phagocytophilum. The presence of B. burgdorferi s.l. was detected in only one of the examined ticks (0.7%). The spread of D. reticulatus to new territories and the increase in population density in areas of their regular occurrence implies the need for further studies of the prevalence of pathogens with medical and veterinary importance in order to assess the risk of tick-borne diseases.
