External layers of Rickettsia prowazekii and Rickettsia rickettsii: occurrence of a slime layer [PDF]
Infection and Immunity, 1978 Using a simple specific-antibody stabilization procedure on organisms gently liberated from their host cells, we have demonstrated by electron microscopy that Rickettsia prowazekii and Rickettsia rickettsii possess a coat of variable thickness, external to the outer leaflet of the cell wall and the structure designated by others as a "microcapsule ...

Effect of immunosuppression on Rickettsia rickettsii infection in guinea pigs [PDF]
Infection and Immunity, 1978 The role of the immune response in the pathogenesis of Rickettsia rickettsii infection in guinea pigs was investigated by immunosuppression, using antilymphocyte serum. Twenty guinea pigs were inoculated with R. rickettsii, Sheila Smith strain, on day 0. Fifteen animals received antilymphocyte serum on days --1, 0, 2, 4, and 6.

Experimental Infection of Amblyomma aureolatum Ticks with Rickettsia rickettsii
Emerging Infectious Diseases, 2011 We experimentally infected Amblyomma aureolatum ticks with the bacterium Rickettsia rickettsii, the etiologic agent of Rocky Mountain spotted fever (RMSF). These ticks are a vector for RMSF in Brazil. R.

Clinical manifestations of Rickettsia rickettsii in a familial outbreak in Panama.
Travel Medicine and Infectious Disease, 2023 We report an isolated outbreak of Rickettsia rickettsii in the Ngäbe-Buglé indigenous region, located 750 m (tropical wet) above sea level, in a jungle and mountainous area of Western Panama. Seven members of a family were infected simultaneously, resulting in four deaths.

Experimental infection of horses with Rickettsia rickettsii. [PDF]
Parasit Vectors, 2016 Rickettsia rickettsii is vectored by ticks, and some vertebrate hosts can be sources of infection to ticks during bacteremic periods. In Brazil, the main vector for R. rickettsii is the tick Amblyomma sculptum, a member of the A. cajennense complex. Horses, in turn, are one of the major hosts for A. sculptum.
