In Europe, spirochetes within the Borrelia burgdorferi sensu lato complex are transmitted by Ixodes ricinus ticks. Specific associations are described between reservoir hosts and individual genospecies. We focused on green lizard (Lacerta viridis) as a host for ticks and potential host for borreliae. In 2004 and 2005, a total of 146 green lizards infested(More)
A new field survey monitoring the spatial distribution of Dermacentor (D.) reticulatus (Fabricius, 1794) tick in Slovakia was carried out in 2005-2008 in order to record changes in its distribution when compared to former studies. Last surveys on the geographical distribution were conducted in 1950s and 1970s and the presence of D. reticulatus was(More)
Tissue samples from nine red foxes (four samples of striated muscle tissue and five samples of heart tissue) that originated from the Michalovce district (Slovakia), an area with endemic occurrence of canine babesiosis were examined by PCR method using primers amplifying a fragment of the 18S rRNA spanning the V4 region of Babesia and Theileria. An(More)
In this study, 746 questing Ixodes (I.) ricinus ticks from eastern Slovakia and 187 ticks from southern Poland were investigated for infection with Borrelia (B.) burgdorferi sensu lato and different outer surface protein A (OspA) types by an improved restriction fragment length polymorphism (RFLP) analysis of the ospA gene. The method enables(More)
Studies were conducted on the role of small mammals in maintaining toxocariasis foci in urban, rural and montane biotopes. The lowest relative density of small mammals was recorded in the urban locality and the highest in the rural and montane localities. Anti-Toxocara antibodies were most frequently detected in synanthropic and hemisynanthropic species Mus(More)
Canine babesiosis is a severe and potentially life threatening infection. In Europe, Babesia canis is considered to be the most common species responsible for the disease. We report two cases of babesiosis caused by Babesia gibsoni. The polymerase chain reaction, restriction fragment length polymorphism analysis and further sequencing of 18S rRNA gene(More)
In order to evaluate the potential risks of human granulocytic anaplasmosis in Slovakia, blood and serum samples of hunters and foresters from the northern parth of Slovakia were tested. We present the first case of HGA from Slovakia confirmed by nested PCR amplification of the 16S rRNA gene fragment of A. phagocytophilum.
Anaplasma phagocytophilum is an obligate intracellular bacterium, circulating in the natural foci in enzootic, vector-host cycle. In Europe, A. phagocytophilum is transmitted by Ixodes ricinus ticks. In Slovakia, cervids which are considered as naturally infected reservoirs of A. phagocytophilum are besides the ticks commonly infested with insects from the(More)
Raising abundance of ticks and tick-borne diseases in Europe is the result of multiple factors including climate changes and human activities. Herein, we investigated the presence and seasonal activity of Ixodes ricinus ticks from 10 urban and suburban sites in two different geographical areas of southeastern and northeastern Slovakia during 2008–2010. Our(More)
Anaplasmoses are common tick-borne zoonotic bacterial diseases of livestock and free-living ungulates from the genus Anaplasma that are recently emerging in Central Europe. The main aim of this study was to analyze the prevalence and genetic variability of Anaplasma phagocytophilum and Anaplasma ovis in small ruminants and questing ticks from six different(More)
