Surface proteins of typhus and spotted fever group rickettsiae [PDF]
Infection and Immunity, 1978 Six proteins, previously established as major constituents of intact organisms, were identified in cell envelopes obtained from intrinsically radiolabeled Rickettsia prowazekii. Extrinsic radioiodination of intact organisms conducted at 0.5 micronM iodide indicated that protein 4 was the most peripheral, although protein 1 also had reactive groups ...

Investigation of Spotted Fever Group Rickettsia Pathogenesis of Mammalian Cells [PDF]
, 2021 Spotted fever group (SFG) Rickettsia are obligate intracellular bacteria that are transmitted by ticks during a bloodmeal to a mammalian host. Interestingly, the SFG pathogen, Rickettsia conorii, has been shown to infect and grow in macrophages with a ...

Genetic variation in Australian spotted fever group rickettsiae [PDF]
Journal of Clinical Microbiology, 1996 Rickettsiae were isolated by cell culture of buffy coat blood from six patients with spotted fever from southeastern Australia and Flinders Island in Bass Strait. The isolates were genetically compared with two previous Rickettsia australis patient isolates.

SPOTTED FEVER GROUP RICKETTSIA IN DOGS IN JAPAN
Japanese Journal of Medical Science and Biology, 1989 Prevalence of antibody against spotted fever group-rickettsia in dogs (14/134) from the northern part of Shikoku Island, where spotted fever group rickettsia infection in human is endemic, is significantly higher than that in dogs (4/189) from nonendemic areas.

A rickettsia infection from Saudi Arabia
International Journal of Infectious Diseases, 2020 We here present a young patient who developed fever, headache, maculopapular skin rash and an eschar 3 days following a tick bite. Serology for Rickettsia was consistent with acute spotted fever group (SFG) infection.

Susceptibility of inbred mice to rickettsiae of the spotted fever group [PDF]
Infection and Immunity, 1984 A mouse strain susceptible to lethal infection with Rickettsia conorii was required for testing vaccine efficacy and for studying the immunology and pathogenesis of infection. Among 20 strains of inbred mice inoculated intraperitoneally with the Malish strain of R.
