Properties of selected rickettsiae of the spotted fever group [PDF]
Infection and Immunity, 1980 Eight strains of spotted fever group rickettsiae were studied to gain insight into the extent of variation of their properties. Two standard strains of Rickettsia rickettsii and one strain of Rickettsia conorii were included among the eight for comparison.

Adherence to and Invasion of Host Cells by Spotted Fever Group Rickettsia Species
Frontiers in Cellular and Infection Microbiology, 2010 The pathogenic lifecycle of obligate intracellular bacteria presents a superb opportunity to develop understanding of the interaction between the bacteria and host under the pretext that disruption of these processes will likely lead to death of the ...

Spotted fever group rickettsiae in ticks in Turkey
Ticks and Tick-borne Diseases, 2014 One hundred twenty-six ticks belonging to 12 tick species were collected from humans, domestic and wild animals, and from the ground as unfed (questing ticks) from distinct localities in Turkey in 2011. Ticks were individually tested by polymerase chain reaction (PCR) for Rickettsia spp., amplifying citrate synthase (gltA), and outer membrane protein ...

Spotted fever group Rickettsiae in Ticks from Missouri
Ticks and Tick-borne Diseases, 2018 Tick-borne rickettsioses pose a major health threat among vector-borne infections in Missouri but there are some uncertainties regarding the vector competence and range of tick species, as well as the virulence of certain bacterial species. A survey was developed and implemented to assess local healthcare practitioners' awareness of the prevalence and ...
