Exotic Rickettsiae in Ixodes ricinus: fact or artifact? [PDF]

, 2010
Several pathogenic Rickettsia species can be transmitted via Ixodes ricinus ticks to humans and animals. Surveys of I. ricinus for the presence of Rickettsiae using part of its 16S rRNA gene yield a plethora of new and different Rickettsia sequences ...

Combined infection with Tomato yellow leaf curl virus and Rickettsia influences fecundity, attraction to infected plants and expression of immunity-related genes in the whitefly Bemisia tabaci.

Journal of General Virology, 2019
We have recently shown that Rickettsia, a secondary facultative bacterial symbiont that infects the whitefly B. tabaci is implicated in the transmission of Tomato yellow leaf curl virus (TYLCV).

A eubacterial origin for the human tRNA nucleotidyltransferase? [PDF]

, 2001
tRNA CCA-termini are generated and maintained by tRNA nucleotidyltransferases. Together with poly(A) polymerases and other enzymes they belong to the nucleotidyltransferase superfamily.

Diversity of Rickettsia in Ticks Collected in Abruzzi and Molise Regions (Central Italy)

Microorganisms, 2019
Rickettsiae have worldwide occurrence and rickettsiosis are widely recognized as emerging infections in several parts of the world. For decades, it was thought that a single pathogenic tick-borne spotted fever group (SFG), Rickettsia, occurred in each ...

tRNA signatures reveal polyphyletic origins of streamlined SAR11 genomes among the alphaproteobacteria [PDF]

, 2013
Phylogenomic analyses are subject to bias from compositional convergence and noise from horizontal gene transfer (HGT). Compositional convergence is a likely cause of controversy regarding phylogeny of the SAR11 group of Alphaproteobacteria that have ...

Microbial diversity in the tick Argas japonicus (Acari: Argasidae) with a focus on Rickettsia pathogens

Medical and Veterinary Entomology, 2019
The soft tick Argas japonicus mainly infests birds and can cause human dermatitis; however, no pathogen has been identified from this tick species in China. In the present study, the microbiota in A.

Rickettsia felisand Changing Paradigms about Pathogenic Rickettsiae

Emerging Infectious Diseases, 2014
To the Editor: Mediannikov et al. recently reported several features common to the epidemiology of Rickettsia felis infection and malaria in Africa (1). Similar to the findings of several other recent studies in Africa (2,3), the authors diagnosed R. felis infection in febrile—and to a lesser extent in afebrile—persons by detecting R.
