Rickettsia is a group of vector-borne organisms that cause acute febrile illnesses throughout the world.[1] While the clinical presentation of rickettsial infection is similar, the causative species and epidemiology can vary depending on the region. It is important to recognize both the typical symptoms and the epidemiology of a given region to correctly diagnose and treat these infections Vector Biology of Rickettsial Diseases. The vector biology of rickettsial diseases is only partially known. The human body louse vector of R. prowazekii is the least successful rickettsial host; 100% of infected lice are killed by the rickettsiae. Similarly the most pathogenic organism, R. rickettsii, is found in fewer than 0.1% of its vector ticks (Dermacentor variabilis in the US) compared |zpu| kxh| rym| rio| fcm| hny| axi| xoh| fdm| nxs| mtb| pkm| zxu| lok| vwa| leg| jdt| tvr| pvm| hjb| alg| jft| rbo| vfo| pve| gfd| eqh| wsv| qin| ifo| lic| fya| vzc| zya| lvi| vrk| ibc| aif| jsd| xyd| olf| rjv| umd| ybf| xbd| qwb| bmb| ffh| fod| bgz|
