Human Infection with Novel Spotted Fever Group Rickettsia Genotype, China, 2015

Emerging Infectious Diseases, 2016
Only 4 species of spotted fever group rickettsiae have been detected in humans in China. However, phylogenetic analysis of samples from 5 ill patients in China indicated infection with a novel spotted fever group Rickettsia, designated Rickettsia sp ...

Improved Detection and Sequencing of Rickettsia spp. DNA in South African Wildlife. [PDF]

Vet Med Sci
Nested gltA PCR detected Rickettsia spp. DNA in 44% of South African wildlife samples previously negative by RLB, revealing spotted fever, typhus and transitional group lineages, novel host records, co‐infection and multi‐organ dissemination in impala, highlighting complex wildlife involvement and zoonotic risk within a One Health framework.

SPOTTED FEVER GROUP RICKETTSIA IN DOGS IN JAPAN

Japanese Journal of Medical Science and Biology, 1989
Prevalence of antibody against spotted fever group-rickettsia in dogs (14/134) from the northern part of Shikoku Island, where spotted fever group rickettsia infection in human is endemic, is significantly higher than that in dogs (4/189) from nonendemic areas.

Rocky Mountain Spotted Fever, Colombia

Emerging Infectious Diseases, 2007
We investigated 2 fatal cases of Rocky Mountain spotted fever that occurred in 2003 and 2004 near the same locality in Colombia where the disease was first reported in the 1930s.

Detection of Orientia spp. Bacteria in Field-Collected Free-Living Eutrombicula Chigger Mites, United States

Emerging Infectious Diseases, 2023
Scrub typhus, a rickettsial disease caused by Orientia spp., is transmitted by infected larval trombiculid mites (chiggers). We report the molecular detection of Orientia species in free-living Eutrombicula chiggers collected in an area in North ...

Rapid, simple, and sensitive detection of the ompB gene of spotted fever group rickettsiae by loop-mediated isothermal amplification

BMC Infectious Diseases, 2012
Background Spotted fever caused spotted fever group rickettsiae (SFGR) is prevalent throughout China. In this study, we describe a rapid, simple, and sensitive loop-mediated isothermal amplification (LAMP) assay targeting the ompB gene of spotted fever ...

Exposure and risk factors to coxiella burnetii, spotted fever group and typhus group Rickettsiae, and Bartonella henselae among volunteer blood donors in Namibia. [PDF]

PLoS ONE, 2014
The role of pathogen-mediated febrile illness in sub-Saharan Africa is receiving more attention, especially in Southern Africa where four countries (including Namibia) are actively working to eliminate malaria.

First Detection of Spotted Fever Group Rickettsiae in Ixodes ricinus from Italy

Emerging Infectious Diseases, 2002
Ixodes ricinus from Italy were examined for the first time to detect whether rickettsiae were present. Using molecular methods, we detected three different spotted fever group rickettsiae, including Rickettsia helvetica. Our results raise the possibility

Q Fever, Scrub Typhus, and Rickettsial Diseases in Children, Kenya, 2011–2012

Emerging Infectious Diseases, 2016
To increase knowledge of undifferentiated fevers in Kenya, we tested paired serum samples from febrile children in western Kenya for antibodies against pathogens increasingly recognized to cause febrile illness in Africa. Of patients assessed, 8.9%, 22.4%

Variations of plasmid content in Rickettsia felis. [PDF]

PLoS ONE, 2008
BACKGROUND: Since its first detection, characterization of R. felis has been a matter of debate, mostly due to the contamination of an initial R. felis culture by R. typhi. However, the first stable culture of R.
