Identifying Novel Inhibitors of RpFabG in Typhus-inducing Rickettsia prowazekii [PDF]

open access: yes, 2019
Epidemic typhus is a rickettsial disease that is contracted via ticks and lice found on the flying squirrel. The disease is caused by Rickettsia prowazekii, an intracellular, gram-negative coccobacillus.

Torix Rickettsia are widespread in arthropods and reflect a neglected symbiosis

open access: yesGigaScience, 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 ...

Metagenomic-based Surveillance of Pacific Coast tick Dermacentor occidentalis Identifies Two Novel Bunyaviruses and an Emerging Human Ricksettsial Pathogen. [PDF]

open access: yes, 2017
An increasing number of emerging tick-borne diseases has been reported in the United States since the 1970s. Using metagenomic next generation sequencing, we detected nucleic acid sequences from 2 novel viruses in the family Bunyaviridae and an emerging ...

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

open access: yesInternational 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 ...

Detection of antibodies anti-Rickettsia spp. in dogs and horses in the state of Mato Grosso, Brazil

open access: yesSemina: Ciências Agrárias, 2014
This study evaluated the infection caused by Rickettsia spp. among dogs and horses from Mato Grosso State. A total of 384 dogs and 460 horses were tested by the Indirect Immunofluorescence Assay (IFA) for Rickettsia rickettsii, Rickettsia parkeri ...

Bartonella infections in fleas (Siphonaptera : Pulicidae) and lack of Bartonellae in ticks (Acari : Ixodidae) from Hungary [PDF]

open access: yes, 2006
Fleas (95 Pulex irritans, 50 Ctenocephalides felis, 45 Ctenocephalides canis) and ixodid ticks (223 Ixodes ricinus, 231 Dermacentor reticulatus, 204 Haemaphysalis concinna) were collected in Hungary and tested, in assays based on PCR, for Bartonella ...

Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia [PDF]

open access: yes, 2001
The current classification of the rhizobia (root-nodule symbionts) assigns them to six genera. It is strongly influenced by the small subunit (16S, SSU) rRNA molecular phylogeny, but such single-gene phylogenies may not reflect the evolution of the ...

New Real-Time PCRs to Differentiate Rickettsia spp. and Rickettsia conorii

open access: yesMolecules, 2020
Rickettsia species are an important cause of emerging infectious diseases in people and animals, and rickettsiosis is one of the oldest known vector-borne diseases. Laboratory diagnosis of Rickettsia is complex and time-consuming. This study was aimed at
