Update on Spotted Fever Group Rickettsiae in South Africa
Vector-Borne and Zoonotic Diseases, 2004Until very recently, Mediterranean spotted fever caused by Rickettsia conorii was the only spotted fever group (SFG) rickettsioses recognized in southern Africa. However, increasing medical awareness of tick-borne infections, together with the introduction of improved isolation methods and the availability of molecular techniques, have led to the ...

Antibodies to spotted fever group rickettsiae in dogs in Croatia
European Journal of Epidemiology, 1995The prevalence of IgG antibodies to spotted fever group rickettsiae was studied by the indirect immunofluorescent antibody assay in a sample of 194 canine sera from different parts of Croatia. Dogs (n = 141) from urban and suburban-semirural environs from the middle part of the eastern coast of Adriatic sea, and dogs (n = 53) from Zagreb, the capital ...

Spotted Fever Group Rickettsia in Yunnan Province, China
Vector-Borne and Zoonotic Diseases, 2012Information about spotted fever group (SFG) rickettsiae in southern China remains sparse. A specific and sensitive real-time PCR assay for detection of SFG rickettsiae was established and used to detect the prevalence rate of SFG rickettsiae in Yunnan Province, China.

A Toxic Substance Associated with the Rickettsias of the Spotted Fever Group
The Journal of Immunology, 1953Summary A toxic substance was demonstrated in yolk sac cultures of ten strains of the spotted fever rickettsia which were selected according to their virulence for guinea pigs, tick-host species, or etiologic relationship to the various diseases of the spotted fever group. These strains included the agents of Rocky Mountain spotted fever,

Mediterranean Spotted Fever And Other Spotted Fever Group Rickettsiae
1998Abstract The spotted fever group of rickettsiae consists of 22 serotypes, or species, of Gram-negative, strictly intracellular bacteria which are associated with ticks and have common antigenic properties. Six strains isolated from patients are recognized as pathogens, while nine others have been isolated only from ticks and are ...

Seroprevalence of Spotted Fever Group Rickettsiae in Dogs in Germany
Vector-Borne and Zoonotic Diseases, 2015Tick-transmitted spotted fever group Rickettsiae (SFGR) are considered emerging disease pathogens in Europe. To assess the situation in Germany, a seroepidemiologic survey of dogs (n=605, which have never left Germany) was conducted to determine the prevalence of antibodies to SFGR. For this purpose, a commercially available enzyme-linked immunosorbent

Serologic Typing of Rickettsiae of the Spotted Fever Group by Microimmunofluorescence
The Journal of Immunology, 1978Abstract The micro-immunofluorescence (micro-IF) method was used to type rickettsiae belonging to the spotted fever or typhus groups according to their surface antigens. Seventy-two strains of rickettsiae from diverse sources, with varying histories of laboratory manipulation and immunologic characterization by other methods, were cross ...
