Exposure of domestic dogs and cats to ticks (Acari: Ixodida) and selected tick-borne diseases in urban and recreational areas in southern Poland

The public health problem of tick-borne diseases has attracted much attention in recent years due to an increasing incidence in humans and animals. The aim of this study was to compare the risk of exposure to ticks and tick-borne infections in dogs and cats in recreational and urbanized areas in the Lesser Poland and Silesian Provinces. For molecular testing for the presence of the selected pathogens, 207 I. ricinus females collected from 119 dogs and 50 cats, and 2 I. hexagonus females collected from 2 domestic dogs, were examined. Overall, A. phagocytophilum was found in 3.7% of the I. ricinus specimens, B. microti in 27.1%, and B. burgdorferi s.l. in 0.9%. In urban areas of both provinces, A. phagocytophilum was found in 4.8% of the I. ricinus specimens, B. microti in 41.6% and B. burgdorferi s.l. in 3.9%. Pathogens were detected B. microti in both studied I. hexagonus specimens. These findings may indicate the important role that these animals play in the circulation of these pathogens in nature.
