| diversionary role of hoofed game in the transmission of lyme disease spirochetes. | to determine whether the presence of ungulates may inhibit transmission of the agent of lyme disease (borrelia burgdorferi) while promoting the abundance of its european vector tick (ixodes ricinus), we compared the feeding density of subadult ticks on roe deer (capreolus capreolus), red deer (cervus elaphus), fallow deer (dama dama), and wild sheep (ovis ammon) near berlin and in brandenburg state, germany. the prevalence of spirochetal infection in these ticks was compared with that in ticks s ... | 1993 | 8517488 |
| seroprevalence study in forestry workers from eastern germany using novel genotype 3- and rat hepatitis e virus-specific immunoglobulin g elisas. | hepatitis e virus (hev) is the causative agent of an acute self-limiting hepatitis in humans. in industrialized countries, autochthonous cases are linked to zoonotic transmission from domestic pigs, wild boar and red deer. the main route of human infection presumably is consumption of contaminated meat. farmers, slaughterers and veterinarians are expected to be risk groups as they work close to potentially infected animals. in this study, we tested four escherichia coli-expressed segments of the ... | 2011 | 22179131 |
| feeding patterns of biting midges of the culicoides obsoletus and culicoides pulicaris groups on selected farms in brandenburg, germany. | host feeding patterns of engorged sibling species of the culicoides obsoletus and culicoides pulicaris groups captured during three nights on two selected farms maintaining either cattle, sheep, horses, and pigs (seedorf, brandenburg) or cattle, sheep, moufflons, and red and fallow deer (paulinenaue, brandenburg) were determined by polymerase chain reaction amplification using conserved primers and sets of species-specific primers derived from vertebrates mitochondrial cytochrome b. out of a tot ... | 2009 | 19308450 |
| evidence for an increased geographical distribution of dermacentor reticulatus in germany and detection of rickettsia sp. rpa4. | two studies were performed to elucidate the current distribution of the tick dermacentor reticulatus in germany. in the first one in 2003, a total of 365 dogs from 171 sites in the states of berlin and brandenburg was screened for ticks, and the corresponding outdoor sites that the dogs usually visited were searched for host-seeking ticks by the flagging method. a total of 1155 ticks was removed from the dogs. the majority were ixodes ricinus (88.5%), followed by d. reticulatus (9.1%) and i. hex ... | 2006 | 16524777 |
