| type iv secretion system components as phylogenetic markers of entomopathogenic bacteria of the genus rickettsiella. | the genus rickettsiella (class gammaproteobacteria; order legionellales; family coxiellaceae) comprises intracellular bacterial pathogens of a wide range of arthropods that are currently classified in the three recognized species, rickettsiella popilliae, rickettsiella grylli, and rickettsiella chironomi. rickettsiella bacteria contain a type ivb secretion system (t4ss) known to be a key virulence factor of the related genus legionella. providing the first respective sequence information for the ... | 2008 | 18179586 |
| 16s rrna-, groel- and mucz-based assessment of the taxonomic position of 'rickettsiella melolonthae' and its implications for the organization of the genus rickettsiella. | 'rickettsiella melolonthae' is an intracellularly multiplying bacterial pathogen of european cockchafers, melolontha melolontha (linnaeus, 1758) and melolontha hippocastani (fabricius, 1801) (coleoptera: scarabaeidae). we report the first determination of nucleotide sequences from this organism, i.e. the 16s rrna encoding rrs gene, the chaperonin encoding groel gene and the mucz gene encoding the orthologue of a capsule synthesis-inducing factor of coxiella burnetii. within the genus rickettsiel ... | 2008 | 18398164 |
| genetic and electron-microscopic characterization of 'rickettsiella agriotidis', a new rickettsiella pathotype associated with wireworm, agriotes sp. (coleoptera: elateridae). | wireworms, the polyphagous larvae of click beetles belonging to the genus agriotes (coleoptera: elateridae), are severe and widespread agricultural pests affecting numerous crops. a previously unknown intracellular bacterium has been identified in a diseased agriotes larva. microscopic studies revealed the subcellular structures characteristic of rickettsiella infections. molecular phylogenetic analysis based on 16s ribosomal rna and signal recognition particle receptor (ftsy) encoding sequences ... | 2011 | 21638041 |
| genetic and electron-microscopic characterization of rickettsiella bacteria from the manuka beetle, pyronota setosa (coleoptera: scarabaeidae). | larvae of manuka beetles, pyronota spp. (coleoptera: scarabaeidae) cause pasture damage in new zealand by feeding on the roots of grasses. surveys for potential biocontrol agents revealed a putative disease, expressed as whitened larvae of one of the outbreak species, pyronota setosa. microbial diagnosis indicated an intracoelomic, intracellular infection, and intracellular bacteria have been identified with subcellular structures characteristic of infection by rickettsiella-like microorganisms. ... | 2011 | 21640120 |
| multilocus sequence typing (mlst) for the infra-generic taxonomic classification of entomopathogenic rickettsiella bacteria. | the genus rickettsiella comprises intracellular bacterial pathogens of a wide range of arthropods that are currently classified in four recognized species and numerous further pathotypes. however, both the delineation of and the synonymization of pathotypes with species are highly problematic. in the sequel of a previous phylogenomic study at the supra-generic level, nine selected genes - the 16s and 23s rrna genes and the protein-encoding genes dnag, ftsy, gida, ksga, rpob, rpsa, and sucb - wer ... | 2011 | 22092813 |
| multilocus sequence analysis (mlsa) of 'rickettsiella agriotidis', an intracellular bacterial pathogen of agriotes wireworms. | wireworms, the polyphagous larvae of click beetles belonging to the genus agriotes (coleoptera: elateridae) are severe and widespread agricultural pests that affect numerous crops globally. a new bacterial specimen identified in diseased wireworms had previously been shown by microscopy and 16s ribosomal rna (rrna) gene-based phylogenetic reconstruction to belong to the taxonomic genus rickettsiella (gammaproteobacteria) that comprises intracellular bacteria associated with and typically pathoge ... | 2013 | 23007524 |
| multilocus sequence analysis (mlsa) of 'rickettsiella costelytrae' and 'rickettsiella pyronotae', intracellular bacterial entomopathogens from new zealand. | larvae of scarab beetles live in the soil and are frequently hosts for microbial pathogens. in new zealand, larvae of the grass grub, costelytrae zealandica (coleoptera: scarabaeidae), and manuka beetles, pyronota spp. (coleoptera: scarabaeidae), have been collected from field populations showing loss of vigour and a whitened appearance. diagnosis indicated an intracellular infection of fat body tissues by rickettsiella-like micro-organisms. rickettsiella bacteria are under evaluation as a possi ... | 2012 | 22856625 |
