Antigenic, morphologic, and molecular characterization of new Ehrlichia risticii isolates.
Ehrlichia risticii causes an acute infectious disease in horses called Potomac horse fever. To investigate the biological diversity of E. risticii organisms, nine E. risticii isolates derived from the peripheral blood monocytes of clinically sick horses in Ohio and Kentucky during the summers of 1991 and 1993 were compared with Illinois and Virginia isolates originally obtained from horses in M...
متن کاملUltrastructure of Ehrlichia canis.
The ultrastructure of Ehrlichia canis was examined in both pulmonary mononuclear cells and in monocytes cultured from an infected dog. The cytoplasmic inclusions, or morulae, of E. canis consisted of a membrane-lined vacuole-containing elementary bodies which varied in size and number. The elementary bodies were bound by two trilamellar membranes. The organism shared morphological properties of...
متن کاملAdaptation of Ehrlichia sennetsu to canine blood monocytes: preliminary structural and serological studies with cell culture-derived Ehrlichia sennetsu.
Ehrlichia sennetsu, the causative agent of human sennetsu rickettsiosis, was successfully propagated in primary canine blood monocyte cultures. The growth cycle of this organism appears to be similar to that of Ehrlichia canis. The antigen derived from our E. sennetsu cultures was used to develop an indirect fluorescent antibody test for detection and titration of serum antibodies to the organi...
متن کاملAntigenic protein modifications in Ehrlichia
To develop effective vaccination strategies against Ehrlichia, we have previously reported developing an animal model of cross-protection in which C57BL/6 mice primed with E. muris were resistant to lethal infection with Ixodes ovatus ehrlichia (IOE). Polyclonal antibody produced in mice after priming with E. muris and later injected with IOE-detected antigenic proteins in E. muris and IOE cell...
