tick-borne rickettsiosis

Etymology: ME, tike + beren + Rickettsia + Gk, osis, condition

any disease transmitted by Ixodid ticks carrying the Rickettsia pathogens, microorganisms smaller than bacteria but larger than viruses. A common infectious species in North America is Rickettsia rickettsii, the cause of Rocky Mountain spotted fever.

tick-borne rickettsiosis

A tick-borne rickettsial infection–eg, north Asian tick-borne rickettsiosis, Queensland tick typhus, and African tick typhus–fiévre boutonneuse, etc, which is similar to RMSF, but less severe, with fever, a small ulcer at the site of the tick bite, satellite lymphadenopathy, and a maculopapular rash. See Rocky Mountain spotted fever.

tick-borne rickettsiosis

The spotted-fever group (SFG) of tick-borne rickettsioses. Included are infections caused by the pathogenic organism Rickettsia rickettsii, which causes Rocky Mountain spotted fever. There are six other pathogenic SFG rickettsial species, five of which (R. conorii, R. sibirica, R. japonica, R. australis, and R. africae) are most likely to be transmitted by a tick bite. R. akari, which causes rickettsialpox, is transmitted to humans by mouse mites.
