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 ...

Rocky Mountain Spotted Fever and Other Spotted Fever Group Rickettsioses
2014Rickettsioses, caused by members of the typhus group and spotted fever group (SFG) rickettsiae, are significant, underrecognized diseases found worldwide. Rocky Mountain spotted fever (RMSF) was first described in the 1890s, and researchers have worked to characterize its manifestations, develop effective therapeutics, examine the biological aspects of

Endemicity of Spotted Fever Group Rickettsiae in Connecticut
The American Journal of Tropical Medicine and Hygiene, 1981To compare rickettsial infectivity and seropositivity rates against spotted fever group (SFG) rickettsiae, ticks and wild mammals were collected from three areas where Rickettsia rickettsii was thought to be enzootic in Connecticut during 1978-1979, and from four additional sites (with no reported human cases) between 1976 and 1979.

Unrecognized Spotted Fever Group Rickettsiosis Masquerading as Dengue Fever in Mexico
The American Journal of Tropical Medicine and Hygiene, 1996Although Rocky Mountain spotted fever was documented in northern Mexico during the 1940s, spotted fever group (SFG) rickettsioses have subsequently received little attention in Mexico. In this study, sera collected in 1993 from 50 patients from the Mexican states of Yucatan and Jalisco, who were suspected clinically to have dengue fever but had no ...

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.
