PURPOSE Human granulocytic anaplasmosis, former ehrlichiosis, is a tick-borne zoonosis of increasing recognition. The aim of the study was: 1) to assess the prevalence of Anaplasma phagocytophilum infection in Ixodes ricinus ticks collected in recreational forests in Bialystok vicinity, the capital of podlaskie voivodship; 2) to evaluate the prevalence of IgG and IgM antibodies to A. phagocytop...

The genetic diversity of Borrelia burgdorferi sensu lato was assessed in a focus of Lyme borreliosis in southern Britain dominated by game birds. Ticks, rodents, and pheasants were analyzed for spirochete infections by PCR-targeting the 23S-5S rRNA genes, followed by genotyping by the reverse line blot method. In questing Ixodes ricinus ticks, three genospecies of B. burgdorferi sensu lato were...

Developmental forms of Babesia spp. were studied in isolated salivary glands of Ixodes ricinus, subjected to the Feulgen reaction. The same ticks were also hosts to Babesia microti, which was determined by PCR amplification with primers specific to the fragment of a gene encoding the nuclear small sub-unit ribosomal RNA (SS-rDNA). Presence of Babesia spp. was recorded in the salivary glands of ...

We report the first molecular evidence of the presence of Babesia sp. EU1 and Babesia microti in Ixodes ricinus ticks in Belgium. A 1-year national survey collected 1005 ticks from cats and dogs. A polymerase chain reaction technique amplifying a part of the 18S rRNA gene detected Babesia spp. in 11 out of 841 selected and validated tick extracts. Subsequent sequencing identified Ba. microti (n...

Fleas (95 Pulex irritans, 50 Ctenocephalides felis, 45 Ctenocephalides canis) and ixodid ticks (223 ixodes ricinus, 231 Dermacentor reticulatus, 204 Haemaphysalis concinna) were collected in Hungary and tested, in assays based on PCR, for Bartonella infection. Low percentages of P. irritans (4.2%) and C. felis (4.0%) were found to be infected. The groEL sequences of the four isolates from P. ir...

Hard ticks are hematophagous arthropods that act as vectors of numerous pathogenic microorganisms of high relevance in human and veterinary medicine. Ixodes ricinus is one of the most important tick species in Europe, due to its role of vector of pathogenic bacteria such as Borrelia burgdorferi and Anaplasma phagocytophilum, of viruses such as tick borne encephalitis virus and of protozoans as ...

Climate warming is changing distributions and phenologies of many organisms and may also impact on vectors of disease-causing pathogens. In Europe, the tick Ixodes ricinus is the primary vector of medically important pathogens (e.g., Borrelia burgdorferi sensu lato, the causative agent of Lyme borreliosis). How might climate change affect I. ricinus host-seeking behavior (questing)? We hypothes...

Lyme disease is one of the infectious diseases discovered in the last three decades. It is a systemic, infectious and zooantropoic disease. Lyme disease is caused by spirochetes Borrelia burgdorferi s.l., and is primarily transferred via Ixodes ticks. Ticks that are vectors for Lyme disease in Europe and also in Serbia are from Ixodes ricinus species (Burgdorfer et all, 1989). Up to date the ex...

The aim of the study was to determine the infection level of adult forms and larvae of ticks and mosquitoes with Borrelia burgdorferi in the forested areas of Szczecin. A total of 1699 ticks Ixodes ricinus, including 1422 nymphs, 277 adult forms and 2862 mosquito females representing the genera Aedes (89.6%) and Culex (10.4%) were collected between the years 2004 and 2005. A further 3746 larvae...

Anaplasma phagocytophilum is an intracellular tick-borne rickettsial pathogen, which causes granulocytic anaplasmosis in various species of livestock and companion animals and also in humans. Previously A. phagocytophilum has been isolated and propagated in cell lines derived from the tick Ixodes scapularis and in the human promyelocytic cell line HL60. In this study we used the Ixodes ricinus-...
