Human Rickettsia heilongjiangensis Infection, Japan

Emerging Infectious Diseases, 2010
A case of Rickettsia heilongjiangensis infection in Japan was identified in a 35-year-old man who had rash, fever, and eschars. Serum contained R. heilongjiangensis antibodies, and eschars contained R. heilongjiangensis DNA. R. heilongjiangensis was also

Acute Tick-borne Rickettsiosis Caused by Rickettsia heilongjiangensis in the Russian Far East

Emerging Infectious Diseases, 2004
An acute tick-borne rickettsiosis caused by Rickettsia heilongjiangensis was diagnosed in 13 patients from the Russian Far East in 2002. We amplified and sequenced four portions of three rickettsial genes from the patients' skin biopsy results and blood ...

Identification of a Ribosomal Protein RpsB as a Surface‐Exposed Protein and Adhesin of Rickettsia heilongjiangensis [PDF]

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Rickettsia heilongjiangensis is an obligate intracellular bacterium that is responsible for far‐eastern spotted fever. Surface‐exposed proteins (SEPs) play important roles in its pathogenesis. Previous work identified a ribosomal protein RpsB as an SEP by biotin‐avidin affinity, a seroreactive antigen, and a diagnostic candidate protein, indicating ...

‘Rickettsia hulinii’ belongs to the Rickettsia heilongjiangensis species [PDF]

Clinical Microbiology and Infection, 2009
A Rickettsia species has long been defined as a distinct serotype using mouse serotyping. However, owing to a lack of reproducibility and interlaboratory comparability of this method, new taxonomic guidelines, based on multigene amplification and sequencing, have been developed and validated by an international panel of rickettsiology experts [1]. This

Detection of "Rickettsia sp. strain Uilenbergi" and "Rickettsia sp. strain Davousti" in Amblyomma tholloni ticks from elephants in Africa [PDF]

BMC Microbiology, 2007
Background To date, 6 tick-borne rickettsiae pathogenic for humans are known to occur in Africa and 4 of them were first identified in ticks before being recognized as human pathogens.

Amplicon-Based Next Generation Sequencing for Rapid Identification of Rickettsia and Ectoparasite Species from Entomological Surveillance in Thailand

Pathogens, 2021
Background: Next generation sequencing (NGS) technology has been used for a wide range of epidemiological and surveillance studies. Here, we used amplicon-based NGS to species identify Rickettsia and their arthropod hosts from entomological surveillance.

Dissemination of spotted fever rickettsia agents in Europe by migrating birds. [PDF]

PLoS ONE, 2010
Migratory birds are known to play a role as long-distance vectors for many microorganisms. To investigate whether this is true of rickettsial agents as well, we characterized tick infestation and gathered ticks from 13,260 migratory passerine birds in ...

Diagnostic Assay for Rickettsia japonica

Emerging Infectious Diseases, 2009
We developed a specific and rapid detection system for Rickettsia japonica and R. heilongjiangensis, the causative agents of spotted fever, using a TaqMan minor groove binder probe for a particular open reading frame (ORF) identified by the R.

Gene Sequence-Based Criteria for Identification of NewRickettsiaIsolates and Description ofRickettsia heilongjiangensissp. nov [PDF]

Journal of Clinical Microbiology, 2003
ABSTRACTWe propose genetic guidelines for the classification of rickettsial isolates at the genus, group, and species levels by using sequences of the 16S rRNA (rrs) gene and four protein-coding genes, thegltA,ompA, andompBgenes and gene D. To be classified as a member of the genusRickettsia, an isolate should exhibit degrees ofrrsandgltAhomology with ...
