Molecular detection of apicomplexan parasites in splenic samples of red foxes collected from northeastern Poland was conducted by PCR amplification of a fragment of the 18S rRNA spanning the V4 gene region of Apicomplexa. Positive PCR products were further analysed by restriction fragment length polymorphism (RFLP) and sequencing to identify species. One hundred and eleven red foxes (Vulpes vulpes) were acquired from 15 localities in the Mazovian Province and 27 foxes were acquired from the Mazurian Lakeland. Apicomplexan 18S rDNA was detected in 15.9% of 138 fox spleens examined. Three apicomplexan species were identified: Hepatozoon canis was detected in 11.6% of the spleen samples, Toxoplasma gondii was detected in 3.6% of the spleen samples and a Babesia sp. was sequenced from 1 sample (0.7%). This data represent the first record of H. canis, T. gondii and a B. sp. from naturally infected red foxes in Poland. Infected foxes may act as sylvatic reservoirs of these apicomplexan parasites as well as serving as a source of infection for arthropod definitive hosts and vectors.
The aim of the study was to elucidate the distribution of Anaplasma phagocytophilum and Babesia microti co-infection in Ixodes ricinus populations within the central-eastern region of Poland. The prevalence of analysed tick-borne human pathogens in single and polymicrobial infections in I. ricinus ticks were analysed using the conventional and nested PCR techniques. A total number of 1,123 questing tick individuals (291 females, 267 males and 565 nymphs) were collected at different ecosystems (municipal parks, suburban forests, and woodlands). In the presented study, 95 samples of ticks (8.5%) were infected with A. phagocytophilum, 3.1% (n=35) with B. microti, whereas the co-existence status of these human pathogens was detected in 1.8% (n=20) of all tested samples. It has been demonstrated that the prevalence of co-infection status was the highest among females of I. ricinus (11 samples, 3.8%), whereas the lowest within tested nymphs (5 samples, 0.9%). Ticks collected at city parks in Warsaw and suburban areas of this town characterized the highest prevalence of co-infections (3.3 and 4.8%, respectively). Furthermore, it was established that co-infection rates of ticks inhabiting woodlands within Kampinos National Park and Nadbużański Landscape Park were similar and reached the levels of 1.4% (n=5) and 1.1% (n=4), respectively.
