| 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 |
| 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 |
