the isolation and characterization of a babesia from red deer (cervus elaphus).on three occasions, antibody positive blood from wild red deer produced overt infections with babesia when inoculated into splenectomized red deer. one of the deer also became infected with eperythrozoon sp. babesia divergens, b. capreoli and the babesia of red deer are morphologically similar and the marginal position of the parasites in the host cell is characteristic. babesia were not seen and no antibody was formed in five out of six splenectomized bovine calves which were injected with para ...1976967525
antigenic, phenotypic and molecular characterization confirms babesia odocoilei isolated from three cervids.babesia isolates from an elk (cervus elaphus canadensis) and a caribou (rangifer tarandus caribou) with fatal infections were compared to babesia odocoilei (engeling isolate) from white-tailed deer (odocoileus virginianus) by experimental infection, serologic, and small subunit ribosomal rna (ssu rrna) gene sequence analysis studies. both the indirect fluorescent antibody test and immunoprecipitation assays demonstrated antigenic variation among the isolates. experimental infection studies showe ...200010941738
[roe deer (capreolus capreolus) and red deer (cervus elaphus) as a reservoir of protozoans from babesia and theileria genus in north-western poland].the species of genus babesia and thelieria are obligate intracellular pathogens that multiply in both vertebrate and invertebrate hosts. some species of babesia cause bovine babesiosis infecting erythrocytes of the cattle and wild ruminants, and undergo a complex developmental cycle in ticks which serve as biological vectors. majority of theileria spp. cause bovine theileriosis infecting lymphocytes as well as erythrocytes of the cattle and wild ruminants, and similar to babesia undergo a comple ...200516913530
babesia spp. identified by pcr in ticks collected from domestic and wild ruminants in southern switzerland.concurrent infections with vector-borne pathogens affected a cattle herd in switzerland, and one of the pathogens was identified as babesia bigemina, which had never been observed in this country before. therefore, a survey of the occurrence of ruminant babesia spp. and their tick vectors in switzerland was conducted. a total of 2,017 ticks were collected from sheep, goats, cattle, and wild ruminants (deer, roe deer, and chamois) in southern parts of switzerland and identified morphologically. t ...200617021198
molecular detection and characterization of piroplasms infecting cervids and chamois in northern spain.wildlife can act as reservoir of different tick-borne pathogens of veterinary and zoonotic importance. to investigate the role of wild ruminants as reservoir of piroplasm infection, 28 red deer, 69 roe deer and 38 chamois from northern spain were examined by reverse line blot (rlb) hybridization. the survey detected a prevalence of 85.7% in red deer, 62.3% in roe deer and 28.9% in chamois. four different piroplasms were identified: theileria sp. ot3 (previously described in sheep) as the most pr ...200717076924
babesias of red deer (cervus elaphus) in ireland.abstract: blood samples were obtained from 38 wild red deer (cervus elaphus) at two sites in ireland and subjected to pcr analysis of the 18s rrna gene followed by sequencing. two fragments of the 18s rrna gene were generated by two different pcr protocols and subsequent sequencing suggested that at least six of the deer were infected by a babesia that, in those loci, is indistinguishable from babesia divergens, an important tick-borne pathogen of cattle and of zoonotic significance. additionall ...201121314977
molecular survey on the presence of zoonotic arthropod-borne pathogens in wild red deer (cervus elaphus).to estimate the prevalence of some zoonotic tick-borne pathogens in red deer (cervus elaphus) living in italian areas with high risk of arthropod exposure, blood samples from 60 red deer were tested by pcr for a. phagocytophilum, borrelia burgdorferi s.l., coxiella burnetii, francisella tularensis, and piroplasms. thirty-four (56.67%) animals resulted positive for one or more pathogens. in particular, 24 (40%) red deer were positive for a. phagocytophilum, 16 (26.67%) for babesia divergens, 6 (1 ...201627477510
molecular analysis of anaplasma phagocytophilum and babesia divergens in red deer (cervus elaphus) in western austria.wild ungulates may act as reservoirs of various vector borne pathogens that can infect humans and domestic animals. in the present study, blood samples from 196 red deer (cervus elaphus) from western austria (vorarlberg, tyrol and salzburg) were collected on filter paper and tested for anaplasmataceae, piroplasmida, rickettsia and filarioid helminths using molecular tools. babesia divergens was detected in ten (5.1%) and anaplasma phagocytophilum in three (1.5%) of the 196 samples. filarioid hel ...201727417532
