Clinical case of spotted fever group rickettsiae [PDF]
International Journal of Infectious Diseases, 2019 We report a Astrakhan ricketsiosis fever in woman who came from Astrakhan. On admission she had fever, intoxication syndrome, exanthema. In complex examination of blood serum by ELISA were reveled IgM and IgG to Rickettsia conorii on the 15th day of the ...

Spotted Fever Group Rickettsiae in Ticks, Germany
Emerging Infectious Diseases, 2011 To explore increased risk for human Rickettsia spp. infection in Germany, we investigated recreational areas and renatured brown coal surface-mining sites (also used for recreation) for the presence of spotted fever group rickettsiae in ticks.

Spotted Fever Group Rickettsiae in and Ticks in Italy
European Journal of Inflammation, 2006 In this study Ixodes ricinus and Haemaphysalis punctata ticks are examined. For the first time we detected Rickettsia conorii in I. ricinus and H. punctata , and Rickettsia sibirica in I. ricinus.

Proteins of typhus and spotted fever group rickettsiae [PDF]
Infection and Immunity, 1976 Purified radioactive rickettsiae were obtained from irradiated and cycloheximide-inhibited L cells, and their proteins were analyzed by polyacrylamide gel electrophoresis. Rickettsial species could be distinguished by comparing the relative mobilities of constituent proteins after migration of two differentially labeled preparations in a single gel ...

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.

Restriction of the growth of a nonpathogenic spotted fever group rickettsia [PDF]
FEMS Immunology & Medical Microbiology, 2012 The growth kinetics of pathogenic and nonpathogenic rickettsiae were compared to elucidate the mechanism responsible for the pathogenicity of rickettsiae. Vero and HeLa cells derived from mammals were inoculated with a nonpathogenic species of spotted fever group rickettsia, Rickettsia montanensis, before being infected with the pathogenic species ...

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 ...

Spotted Fever Group and Typhus Group Rickettsioses in Humans, South Korea
Emerging Infectious Diseases, 2005 The presence of the nucleic acid of the spotted fever group (SPG) and typhus group (TG) rickettsiae was investigated in 200 serum specimens seropositive for SFG rickettsiae by multiplex-nested polymerase chain reaction with primers derived from the ...

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.
