Relative efficiency of biological transmission of Anaplasma marginale (Rickettsiales: Anaplasmataceae
) by Dermacentor andersoni (Acari: Ixodidae) compared with mechanical transmission by Stomoxys calcitrans (Diptera: Muscidae).
Prevalence of Borrelia burgdorferi (Spirochaetales: Spirochaetaceae), Anaplasma phagocytophilum (Rickettsiales: Anaplasmataceae
), and Babesia microti (Piroplasmida: Babesiidae) in Ixodes scapularis (Acari: Ixodidae) collected from recreational lands in the Hudson Valley Region, New York State.
 There are currently three groups of diseases commonly identified as rickettsioses: (i) spotted fever group (SFG) and typhus group (TG) rickettsial infections; (ii) scrub typhus, associated with Orientia tsutsugamushi (formerly Rickettsia tsutsugamushi); and (iii) human ehrlichioses and anaplasmosis caused by pathogens in the family Anaplasmataceae
. [3,4,8-10] Rickettsioses do not have any specific pathognomonic signs, but rather a range of generalised signs and symptoms that may include fever, rash, lymphadenopathy and headache.
In cattle, anaplasmosis caused by different genres of Anaplasma (Rickettsiales: Anaplasmataceae
) including Anaplasma marginale (A.
Reorganization of gene in families Rickettsiaceae and Anaplasmataceae
in the order Rickettsiales: unification of some species of Ehrlichia with Anaplasma, Cowdria with Ehriichia with neorickettsia, description of six new species combinations and designations.
Reorgarnization of genera in the families Rickettsiaceae and Anaplasmataceae
in the order Rickettsiales: unification of some species of Ehrlichia with Anaplasma, Cowdria with Ehrlichia and Ehrlichia with Neorickettsia, descriptions of six new species combinations and designation of Ehrlichia equi and HGE agent' as subjective synonyms of Ehrlichia phagocytophila.
pipientis, the nomen of the genus, forms a monophyletic clade within the Alphaproteobacteria class, closely related to the Anaplasma, Ehrlichia and Neorickettsia genera of the Anaplasmataceae
Anaplasma marginale (Rickettsiales: Anaplasmataceae
): recent advances in defining host-pathogen adaptations of a tick-borne rickettsia.
Molecular diagnosis of Anaplasmataceae
organisms in dogs with clinical and microscopical signs of ehrlichiosis.
For example, Palmer and colleagues studied the surface proteome of the tick-borne intracellular pathogen Anaplasma marginale (Rickettsiales: Anaplasmataceae
) using liquid chromatography and tandem MS .
