The genus Rickettsia encompasses a large group of obligate intracellular, Gram-negative bacteria that fall under the family Rickettsiaceae, order Rickettsiales, class Alphaproteobacteria, phylum Proteobacteria. The family Rickettsiaceae consists of three … The classification of Rickettsia into three groups (spotted fever, typhus, and scrub typhus) was initially based on serology. This grouping has since been confirmed by DNA sequencing. All three of these groups include human pathogens.
