Rickettsiaceae are small bacteria in the family Rickettsiaceae and are fastidious, nonmotile, aerobic, gram-negative, obligate intracellular bacteria that survive only briefly outside the host.
There are two families of bacteria that cause rickettsioses: Rickettsiaceae (Rickettsia and Orientia) and Anaplasmataceae (Anaplasma, Neorickettsia, and Ehrlichia).
A BLAST search was conducted with this sequence (GenBank accession EF433794) that produced significant alignments to multiple Wolbachia species in the [alpha]-proteobacterial family Rickettsiaceae
. This sequence was different than the 16S rRNA sequence from Wolbachia obtained from the Florida population of D.
Reorganization of genera in the families Rickettsiaceae
and Anaplasmataceae in the order Rickettsiales: unification of some species of Ehrlichia with Anaplasma, Cowdria with Ehrlichia and Erlichia with Neorickettsia, descriptions of six new species combinations and designation of Erlichia equi and HE agent as subjective synonyms of Ehrlichia phagocytophila.
Of the 20,575,878 shotgun sequencing reads generated, [approximately equal to] 12% matched Rickettsiaceae.
Although reference sequences are available for multiple Rickettsiaceae, R.
The primers were chosen to be specific for bacteria belonging to the families Rickettsiaceae
and Anaplasmataceae (10), but they also amplified Bartonella spp.
The family Rickettsiaceae
includes the genera Rickettsia and Orientia (1).

Rickettsia felis (Rickettsiales: Rickettsiaceae
) in Ctenocephalides felis felis (Siphonaptera: Pulicidae) in the State of Silo Paulo, Brazil.
Scrub typhus, a widely endemic disease in Asian Pacific regions, is caused by Orientia tsutsugamushi, a gram-negative obligate intracellular bacterium in the family Rickettsiaceae
. When the rickettsia is transmitted to a human through the bite of an infected mite, it begins to multiply at the bite site, and a characteristic skin lesion known as an eschar is formed.
