... Some species of Rickettsia are known to cause harmful diseases in humans, such as epidemic typhus (R. prowazekii) and Rocky Mountain spotted fever (R. rickettsii), while others have been identified as emerging pathogens and critical agents for the development of bioweapons. The Rickettsia felis bacteriu...2-step process filters evolution of genes of human and chimpanzee
