Dermacentor reticulatus plays an important role in the maintenance of pathogens of medical and veterinary importance in the environment. Currently two isolated populations of D. reticulatus are present in Poland –Western and Eastern. The range of the Eastern population covers endemic areas in eastern Poland but this population is expanding westwards(More)
Rapid expansion of the tick Dermacentor reticulatus (Fabricius) has been reported in many European countries. In Poland its range was limited to the area on the eastern side of the Vistula River up until the 1990s. However, new foci were recently discovered, while the centre of the country and mountain regions are believed to be free of this tick and are(More)
Gastrointestinal stromal tumors (GIST) mutational status is recognized factor related to the results of tyrosine kinase inhibitors therapy such as imatinib (IM) or sunitinib (SU). Arterial hypertension (AH) is common adverse event related to SU, reported as predictive factor in renal cell carcinoma. The aim of the study was to analyze the outcomes and(More)
INTRODUCTION AND OBJECTIVE Tick-borne infections constitute an increasing health problem in dogs and may lead to death, especially in young or elderly individuals. Canine babesiosis constitutes a serious health problem in dogs worldwide. The aim of the study was to verify the probability of vertical transmission of Babesia canis between the bitch and the(More)
Babesia spp. (Apicomplexa, Piroplasmida) are obligate parasites of many species of mammals, causing a malaria-like infection- babesiosis. Three routes of Babesia infection have been recognized to date. The main route is by a tick bite, the second is via blood transfusion. The third, vertical route of infection is poorly recognized and understood. Our study(More)
Although a number of new species of Babesia/Theileria have been described recently, there are still relatively few reports of species from Africa. In this study based on the evaluation of morphology and phylogenetic relationships, we describe a novel species from Wagner’s gerbil, Babesia behnkei n. sp. Rodents (n = 1021) were sampled in four montane valleys(More)
The impact of agricultural practices/ activities on the environment has been falling in many areas of Europe due to the widespread exodus of inhabitants from rural areas. The associated abandonment of agricultural lands has enabled a wide range of wild animals to prosper in the countryside, including birds, ungulates and large carnivores. One consequence(More)
The most common tick species parasitizing animals in Poland are Ixodes ricinus and Dermacentor reticulatus. These tick species differ in their distribution, habitats, seasonal activity and host specificity. Ixodes ricinus is the most prevalent and widely distributed, whereas the range of D. reticulatus is limited to eastern and central parts of the country(More)
The identification of prognostic factors in cutaneous melanoma allows choosing the most effective treatment, especially in group of patients with locoregional disease. Markers related to carcinogenesis and angiogenesis in particular have effect on the course of the disease. The aim of this study was to evaluate clinical utility of vascular endothelial(More)
OBJECTIVE The aim of the present study was to verify whether selected functional single nucleotide polymorphisms in LEP, LEPR, and ADIPOQ loci are associated with the development of obesity and serum levels of the respective adipokines in prepubertal white children with obesity. METHODS Frequencies of -2548G>A LEP (rs7799039), Q223R (rs1137101) and K656N(More)
