seroprevalence of human granulocytic anaplasmosis in berlin/brandenburg, germany: an 8-year survey.	this study investigated the seroprevalence of antibodies against anaplasma phagocytophilum in berlin/brandenburg, north-eastern germany. during 1994-2001, 422 sera from patients with proven tick-exposure (specimens with antibodies against borrelia burgdorferi) were compared with 249 control sera. using indirect fluorescent antibody testing, significantly more positive samples were detected among borrelia antibody-positive specimens (4.5%, 95% ci 2.5-6.5%) than among controls (1.2%, 95% ci 0.5-1. ...	2006	16882301
[seroprevalence of anaplasma phagocytophilum infection in dogs in germany].	to determine the prevalence of anaplasma phagocytophilum in dogs in germany serum samples from 1124 dogs that were under suspicion of having anaplasmosis were examined. the samples were tested by an indirect immunofluorescence test (oft) for antibodies to a. phagocytophilum. the geographical origin of positive cases were analysed with an geographic information system. antibodies to a. phagocytophilum were found in 563 (50.1%) of the tested dogs. 166 dogs came from saarland, 161 from north rhine- ...	2006	17009720
pathogens and host dna in ixodes ricinus nymphal ticks from a german forest.	unfed nymphs of ixodes ricinus were collected from vegetation in a forest on the outskirts of berlin, germany and were analyzed for host and pathogen dna. pathogens were detected in 47% of the ticks. borrelia afzelii was the commonest pathogen detected, followed by rickettsia helvetica. other pathogens included b. valaisiana, b. garinii, b. burgdorferi sensu stricto, anaplasma phagocytophilum, and a relapsing fever-like borrelia. most of the host dna detected was of rodent origin and was associa ...	2006	17187573
absence of borrelia spp., candidatus neoehrlichia mikurensis, and anaplasma phagocytophilum in questing adult dermacentor reticulatus ticks.	to determine whether dermacentor reticulatus ticks are infected by borrelia spp., candidatus neoehrlichia mikurensis, or anaplasma phagocytophilum, we collected questing adults in the outskirts of berlin, germany, examined them for the presence of dna of these pathogens, and compared the infection rates to those of sympatric ixodes ricinus ticks. questing d. reticulatus adults appeared not to harbor the bacterial pathogens that are prevalent in i. ricinus ticks. based on our sample size, the est ...	2013	22955502
[prevalence of haemotropic mycoplasma spp., bartonella spp. and anaplasma phagocytophilum in cats in berlin/brandenburg (northeast germany)].	aim of this study was to evaluate the occurrence of mycoplasma (m.) haemofelis, candidatus mycoplasma (c. m.) turicensis, c m. haemominutum, bartonella spp. (b. henselae, b. clarridgeiae and b. quintana) and anaplasma (a.) phagocytophilum in cats in northeast germany in relation to their living conditions (indoor/outdoor/ stray cat), and tick/flea exposure. 265 cats were included in the study (150 indoor, 99 outdoor access, 16 stray cats). a questionnaire provided the following data: derivation, ...	2012	23045805
pathogens in ticks collected from dogs in berlin/brandenburg, germany.	tick-borne diseases are a major health risk for humans and dogs. in addition to collection and analysis of questing ticks, analysis of host-associated ticks for the presence of pathogens is a valuable method to gain insight into transmission patterns of tick-borne diseases.	2014	25441762
