AB The  human  pathogens  in  the  family  Rickettsiaceae  are  small  bacteria  of  the  genera  Rickettsia  and  Orientia.  They  are  closely  related  to  members  of  the  family  Anaplasmataceae  that  includes  the  genera  Ehrlichia  and  Anaplasma.  These  organisms  are  obligate  intracellular  parasites  that  are  transmitted  to  humans  by  arthropods.  Many  rickettsiae  are  transmitted  transovarially  in  the  arthropod,  which  serves  as  both  vector  and  reservoir.  Rickettsial  infections,  but  not  the  ehrlichioses,  typically  are  manifested  by  fever,  rashes,  and  vasculitis.  They  are  grouped  on  the  basis  of  their  clinical  features,  epidemiologic  aspects,  and  immunologic  characteristics  (Table  26-1).  Coxiella  burnetii  resides  in  the  family  Coxiellaceae  and  is  more  closely  related  to  the  genus  Legionella;  for  convenience,  it  is  discussed  at  the  end  of  this  chapter.
