Isolation of Rickettsia heilongjiangensis strains from humans and ticks and its multispacer typing [PDF]

Clinical Microbiology and Infection, 2009
Tick-borne rickettsiosis in the far east of Russia was simultaneously observed in 1932 in two neighbouring territories: in the Primorye (Maritime) region by E. I. Mill and in the Khabarovsk region by N. I. Antonov and A. G. Naishtat [1,2]. The described illness was acute and febrile; skin manifestation presented with maculopapular rash, sometimes ...

Identification of a new serotype of Rickettsia heilongjiangensis in wild rats from Guangdong Province, China [PDF]

Clinical Microbiology and Infection, 2009
Spotted fever (SF) rickettsioses are acute febrile, mostly tick-borne infections caused by obligate intracellular bacteria of the genus Rickettsia. In China, three rickettsiae SF groups, including Rickettsia sibirica subsp. sibirica, R. sibirica subsp. mongolitimonae, and Rickettsia heilongjiangensis, have been isolated in humans [1].

Rickettsia heilongjiangensis suppresses RIPK1 kinase-mediated host cell death during the infection

Infection and Immunity
Spotted fever group Rickettsia (SFGR) poses a significant challenge in the field of tick-borne diseases, characterized by its obligate intracellular lifestyle and its ability to disrupt various host cellular pathways. A deeper understanding of Rickettsia’

New approaches in the systematics of rickettsiae

New Microbes and New Infections, 2018
The development of a formal order analysis (FOA) allowed constructing a classification of 49 genomes of Rickettsiaceae family representatives. Recently FOA has been extended with new tools—‘Map of genes,’ ‘Matrix of similarity’ and ‘Locality-sensitive ...
