Spotted Fever Group Rickettsial Infections in Australia

Clinical Infectious Diseases, 1991
More than four decades ago, Rickettsia australis was discovered to be the etiologic agent of Queensland tick typhus (QTT), yet many unanswered questions persist about the ecology, epidemiology, and clinical features of this disease. We review 46 previously published cases of QTT along with 16 cases discovered by active surveillance.

Mediterranean Spotted Fever And Other Spotted Fever Group Rickettsiae

1998
Abstract 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 ...

Spotted Fever Group Rickettsia Infection of Cats and Cat Fleas in Northeast Thailand

Vector Borne and Zoonotic Diseases, 2020
Rickettsia species cause rickettsioses, which are zoonotic diseases found worldwide, and are transmitted by arthropods such as lice, fleas, ticks, and mites. In Thailand, flea infestations are common among cats and dogs.

Rocky Mountain Spotted Fever and Other Spotted Fever Group Rickettsioses

2014
Rickettsioses, 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

Spotted Fever Group Rickettsia in Yunnan Province, China

Vector-Borne and Zoonotic Diseases, 2012
Information 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.

Endemicity of Spotted Fever Group Rickettsiae in Connecticut

The American Journal of Tropical Medicine and Hygiene, 1981
To 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.
