Japanese spotted fever, a tickborne disease caused by Rickettsia japonica, has been reported in Japan, Korea, and China (1-3).
[4] There are currently three groups of diseases commonly identified as rickettsioses: (i) spotted fever group (SFG) and typhus group (TG) rickettsial infections; (ii) scrub typhus, associated with Orientia tsutsugamushi (formerly Rickettsia tsutsugamushi); and (iii) human ehrlichioses and anaplasmosis caused by pathogens in the family Anaplasmataceae.
Rickettsia diseases are caused by small intracellular Gram-negative rod-shaped bacteria that are members of the order Rickettsiales and family Rickettsiaceae in the Proteobacteria [alpha]-subdivision (RAOULT & ROUX, 1997; DUMLER et al., 2001).
Because Rickettsia is an intracellular pathogen, in vitro culture (typically cell culture) is complex (Fryer & Lannan 1994).
Because of this, very little is known about the transmission dynamics of Rickettsia species in rural areas of Yucatan.
DETECTION OF RICKETTSIA RICKETTSII BRUMPT (RICKETTSIALES: RICKETTSIACEAE) IN THE BROWN DOG TICK RHIPICEPHALUS SANGUINEUS LATREILLE (IXODIDA: IXODIDAE) IN THE COMARCA LAGUNERA, A REEMERGENT SPOTTED FEVER ZONE IN MEXICO
The Gram-negative Rickettsia bacteria are arthropod vector-borne and worldwide distributed [13, 14].
Besides primary endosymbionts, white fly harbors secondary endosymbionts namely Hamiltonella (Zchori-Fein and Brown, 2002), Rickettsia (Gottlieb et al., 2006), Cardinium (Zchori-Fein and Perlman, 2004), Fritschea (Everett et al., 2005), Arsenophonus (Baumann et al., 2004) and Wolbachia (Skaljac et al., 2010; Tram et al., 2003).
Rickettsiae and related ehrlichial organisms are obligate intracellular bacteria carried by mites, fleas, ticks, and lice and are the agents of numerous tick-borne diseases found in Virginia, such as Rocky Mountain spotted fever (Rickettsia rickettsii), Tidewater spotted fever (Rickettsia parkeri), Human monotropic ehrlichiosis (Ehrlichia chaffeensis), and Ewingii ehrlichiosis (Ehrlichia ewingii).
Rickettsia bacteria are spread to people and pets through the bite of an infected tick.
During 2012-2014, five cases of Rickettsia parkeri rickettsiosis were identified by a single urgent care practice in Georgia, located approximately 40 miles southwest of Atlanta.
