GENOMOSYSTEMATICS OF RICKETTSIAE

Инфекция и иммунитет, 2018
The definition of the term genome was given by the German botanist G. Winkler almost one hundred years ago in 1920. A genome  definition for bacterial (rickettsia) with a single chromosome was  recently presented from the perspective of information ...

Phylogenetic analysis of the rompB genes of Rickettsia felis and Rickettsia prowazekii European-human and North American flying-squirrel strains.

, 2000
The rickettsial outer membrane protein B (rompB) gene encodes the major surface antigens of Rickettsia species. We undertook sequencing and molecular analysis of the rompB gene of Rickettsia felis and a comparison with its homologs in spotted fever group

Transposon mutagenesis of the obligate intracellular pathogen Rickettsia prowazekii

, 2004
Genetic analysis of Rickettsia prowazekii has been hindered by the lack of selectable markers and efficient mechanisms for generating rickettsial gene knockouts.

Molecular detection of medically important rickettsiae, including Rickettsia prowazekii in Rhipicephalus appendiculatus and Hyalomma rufipes: A microbiome perspective

Ticks and Tick-Borne Diseases
The East African region hosts more than 50 % of Africa livestock and 9 % of global cattle, creating an ideal environment for ticks to thrive and transmit pathogens.

Potential role of head lice, Pediculus humanus capitis, as vectors of Rickettsia prowazekii

, 2003
Since the pioneering work of Charles Nicolle in 1909 [see Gross (1996) Proc Natl Acad Sci USA 93:10539-10540] most medical officers and scientists have assumed that body lice are the sole vectors of Rickettsia prowazekii, the aetiological agent of louse ...

Evidence of Exposure to Multiple Zoonotic Pathogens in Humans in Lusaka, Zambia: Insights from Metagenomic Next-Generation Sequencing

Zoonotic Diseases
Zoonotic diseases present a growing public health challenge, particularly in sub-Saharan Africa (SSA) due to close interactions between humans and animals and poor diagnostic capacity. This pilot study investigated human exposure to zoonotic pathogens in
