Molecular detection of Rickettsia infection in field-collected bed bugs

New Microbes and New Infections, 2020
Bed bugs are now one of the most prevalent human-associated, blood-feeding pests in the urban world, but few studies of their association with human pathogens have been conducted since their resurgence.

Characterization of spotted fever group Rickettsiae in ticks from a city park of Rome, Italy

Annali dell'Istituto Superiore di Sanità, 2015
BACKGROUND: Ticks are vectors and important reservoirs for microbial agents that cause disease in humans and animals. Among these pathogens, the members of Rickettsia species play an important role in public health.

Rickettsia in the Regiment [PDF]

Journal of the Royal Army Medical Corps, 1989
A case of Rocky Mountain Spotted Fever (RMSF) is described, together with other cases of pyrexia whose occurrence originally gave the impression of a significant outbreak of the disease in a TA regiment after annual training in the USA. The role of the RMO is considered in such circumstances.

First detection and molecular identification of Rickettsia massiliae, a human pathogen, in Rhipicephalus sanguineus ticks collected from Southern Taiwan.

PLoS Neglected Tropical Diseases, 2022
The Rickettsia massiliae was firstly detected and identified in Rhipicephalus sanguineus ticks infested on dogs in Taiwan. A total of 1154 Rh. sanguineus ticks collected from 158 dogs of four districts of Tainan city were examined for Rickettsia ...

Torix Rickettsia are widespread in arthropods and reflect a neglected symbiosis

GigaScience, 2020
Background Rickettsia are intracellular bacteria best known as the causative agents of human and animal diseases. Although these medically important Rickettsia are often transmitted via haematophagous arthropods, other Rickettsia, such as those in the ...

Immunoproteomic profiling of Rickettsia parkeri and Rickettsia amblyommii

Ticks and Tick-borne Diseases, 2015
Rickettsia parkeri is an Amblyomma-associated, spotted fever group Rickettsia species that causes an eschar-associated, febrile illness in multiple countries throughout the Western Hemisphere. Many other rickettsial species of known or uncertain pathogenicity have been detected in Amblyomma spp.

Risk1, a Phosphatidylinositol 3-Kinase Effector, Promotes Rickettsia typhi Intracellular Survival

mBio, 2020
Rickettsia species are Gram-negative obligate intracellular bacteria that infect a wide range of eukaryotes and vertebrates. In particular, human body louse-borne Rickettsia prowazekii and flea-borne Rickettsia typhi have historically plagued humankind ...

Comparative ultrastructural study on the cell envelopes of Rickettsia prowazekii, Rickettsia rickettsii, and Rickettsia tsutsugamushi [PDF]

Infection and Immunity, 1978
Rickettsia tsutsugamushi differs from other rickettsiae in its cell envelope organization. The differences were made evident through a comparative study of the outer envelope of R. tsutsugamushi, R. prowazekii, and R. rickettsii by electron microscopy.

Genome sequence-based criteria for demarcation and definition of species in the genus Rickettsia.

International Journal of Systematic and Evolutionary Microbiology, 2020
Over recent years, genomic information has increasingly been used for prokaryotic species definition and classification. Genome sequence-based alternatives to the gold standard DNA-DNA hybridization (DDH) relatedness have been developed, notably average ...
