[imported arthropod-borne parasites and parasitic arthropods in dogs. species spectrum and epidemiologic analysis of the cases diagnosed in 1995/96].	between january 1995 and december 1996 nonendemic or only regionally occurring arthropodborne parasites including ehrlichiae and parasitic arthropods in germany were detected in 484 dogs, whereby at least 15 species were involved. listed in decreasing order, leishmania infections occurred most frequently, followed by infections/infestations with babesia canis, ehrlichia canis, rhipicephalus sanguineus, dirofilaria immitis and dermacentor reticulatus. the other species, namely babesia gibsoni, tr ...	1998	9531673
tick-borne bacteria in free-living jaguars (panthera onca) in pantanal, brazil.	abstract tick-borne bacteria were investigated in 10 free-living jaguars and their ticks in the pantanal biome, brazil. jaguar sera were tested by indirect fluorescent antibody assays using rickettsia rickettsii, rickettsia parkeri, rickettsia amblyommii, rickettsia rhipicephali, rickettsia felis, rickettsia bellii, ehrlichia canis, and coxiella burnetii as crude antigens. all 10 jaguar sera reacted (titer ≥64) to at least one rickettsia species; 4 and 3 sera reacted with e. canis and c. burneti ...	2011	21612532
ultrastructure of ehrlichia mineirensis, a new member of the ehrlichia genus.	recently, we reported the in vitro isolation and the molecular characterization of a new species of ehrlichia (ehrlichia mineirensis) from haemolymph of brazilian rhipicephalus (boophilus) microplus ticks. this organism shows an ortholog of ehrlichia canis major immunogenic protein gp36 with a new structure of tandem repeats. in the present study, we used electron microscopy (high pressure freezing and freeze substitution preparative techniques) to characterize morphologically this new agent gro ...	2013	23998429
in vitro culture of a novel genotype of ehrlichia sp. from brazil.	ehrlichiae are obligate intracytoplasmic gram-negative, tick-borne bacteria belonging to the anaplasmataceae family. ehrlichioses are considered emerging diseases in both humans and animals. several members of the genus ehrlichia have been isolated and propagated in vitro. this study describes the continuous propagation of a brazilian ehrlichia sp. isolate in ide8 tick cells, canine dh82 cells and bovine aorta cells. initially, the organisms were isolated from the haemolymph of a rhipicephalus ( ...	2013	24589106
complete genome sequence of ehrlichia mineirensis, a novel organism closely related to ehrlichia canis with a new host association.	we report here the complete genome sequencing of ehrlichia mineirensis, an ehrlichia organism that was isolated from the hemolymph of rhipicephalus microplus-engorged females. e. mineirensis is the best characterized ehrlichia isolate from a novel cattle-related clade closely related to the monocytotropic pathogen e. canis.	2015	25614563
identification of intestinal bacterial flora in rhipicephalus microplus ticks by conventional methods and pcr-dgge analysis.	in this study, we have analyzed the intestinal microbial flora associated with rhipicephalus microplus ticks using both culture-dependent and independent methods based on pcr and denaturing gradient gel electrophoresis (pcr-dgge). the r. microplus ticks were collected from cattle and goats in jiangxi, hunan and guizhou provinces of china. three distinct strains of bacteria were isolated using culture-dependent methods: staphylococcus simulans, bacillus subtilis and bacillus flexus strain. ninete ...	2015	25784070
molecular epidemiological surveillance to assess emergence and re-emergence of tick-borne infections in tick samples from china evaluated by nested pcrs.	an investigation was performed to detect eight pathogens in ticks collected from grass tips or animals in the southern, central and northeast regions of china. dna samples extracted from ticks were collected from ten different locations in eight provinces of china and subjected to screening for tick-borne pathogens, including borrelia burgdorferi sensu lato, ehrlichia spp., rickettsia spp., babesia/theileria spp., ehrlichia ruminantium, coxiella burnetii, and francisella tularensis, using nested ...	2016	26943995
minimum infection rate of ehrlichia minasensis in rhipicephalus microplus and amblyomma sculptum ticks in brazil.	a new genotype phylogenetically close to ehrlichia canis named as ehrlichia minasensis was identified infecting cattle and deer in canada, as well as rhipicephalus microplus ticks and cattle in brazil. although it was detected in r. microplus, little is known about the epidemiology of this ehrlichiosis, especially in other tick species. this study evaluated the minimum infection rate of e. minasensis in amblyomma sculptum and r. microplus ticks from locations where naturally infected cattle were ...	2016	27084673
