Prevalence of Cardinium Bacteria in Planthoppers and Spider Mites and Taxonomic Revision of “ Candidatus Cardinium hertigii” Based on Detection of a New Cardinium Group from Biting Midges

Citation

Names
Ca. Cardinium hertigii “Cardinium hertigii”
Abstract
ABSTRACT Cardinium bacteria, members of the phylum Cytophaga - Flavobacterium - Bacteroides (CFB), are intracellular bacteria in arthropods that are capable of inducing reproductive abnormalities in their hosts, which include parasitic wasps, mites, and spiders. A high frequency of Cardinium infection was detected in planthoppers (27 out of 57 species were infected).

The Ultramicrobacterium “ Elusimicrobium minutum ” gen. nov., sp. nov., the First Cultivated Representative of the Termite Group 1 Phylum

Citation
Geissinger et al. (2009). Applied and Environmental Microbiology 75 (9)
Names
Elusimicrobiota
Abstract
ABSTRACT Insect intestinal tracts harbor several novel, deep-rooting clades of as-yet-uncultivated bacteria whose biology is typically completely unknown. Here, we report the isolation of the first representative of the termite group 1 (TG1) phylum from sterile-filtered gut homogenates of a humivorous scarab beetle larva. Strain Pei191 T is a mesophilic, obligately anaerobic ultramicrobacterium with a gram-negative cell envelope. Cells are typically

Tissue-Associated “ Candidatus Mycoplasma corallicola” and Filamentous Bacteria on the Cold-Water Coral Lophelia pertusa (Scleractinia)

Citation
Neulinger et al. (2009). Applied and Environmental Microbiology 75 (5)
Names
Ca. Mycoplasma corallicola
Abstract
ABSTRACT The cold-water coral Lophelia pertusa (Scleractinia, Caryophylliidae) is a key species in the formation of cold-water reefs, which are among the most diverse deep-sea ecosystems. It occurs in two color varieties: white and red. Bacterial communities associated with Lophelia have been investigated in recent years, but the role of the associated bacteria remains largely obscure. This study uses catalyzed reporter depos

“ Candidatus Midichloria” Endosymbionts Bloom after the Blood Meal of the Host, the Hard Tick Ixodes ricinus

Citation
Sassera et al. (2008). Applied and Environmental Microbiology 74 (19)
Names
Ca. Midichloria
Abstract
ABSTRACT “ Candidatus Midichloria mitochondrii,” an intracellular symbiont of the tick Ixodes ricinus , is the only described organism able to invade the mitochondria of any multicellular organism. We used quantitative PCR to examine cycles of bacterial growth and death throughout the host's development and found that they correspond with the phases of engorgement and molt, respectively.

A New Huanglongbing Species, “ Candidatus Liberibacter psyllaurous,” Found To Infect Tomato and Potato, Is Vectored by the Psyllid Bactericera cockerelli (Sulc)

Citation
Hansen et al. (2008). Applied and Environmental Microbiology 74 (18)
Names
Ca. Liberibacter psyllaurous
Abstract
ABSTRACT A new huanglongbing (HLB) “ Candidatus Liberibacter” species is genetically characterized, and the bacterium is designated “ Candidatus Liberibacter psyllaurous.” This bacterium infects the psyllid Bactericera cockerelli and its solanaceous host plants potato and tomato, potentially resulting in “psyllid yellowing.” Host plant-dependent HLB transmission and variation in psyllid infection frequ

Evolution of the Secondary Symbiont “ Candidatus Serratia symbiotica” in Aphid Species of the Subfamily Lachninae

Citation
Lamelas et al. (2008). Applied and Environmental Microbiology 74 (13)
Names
Ca. Serratia symbiotica
Abstract
ABSTRACT Buchnera aphidicola BCc, the primary endosymbiont of the aphid Cinara cedri (subfamily Lachninae), is losing its symbiotic capacity and might be replaced by the coresident “ Candidatus Serratia symbiotica.” Phylogenetic and morphological analyses within the subfamily Lachninae indicate two different “ Ca . Serratia symbiotica” lineages and support the longtime coevolution of both s

Proteomic Analysis of Stationary Phase in the Marine Bacterium “ Candidatus Pelagibacter ubique”

Citation
Sowell et al. (2008). Applied and Environmental Microbiology 74 (13)
Names
Ca. Pelagibacter ubique
Abstract
ABSTRACT “ Candidatus Pelagibacter ubique,” an abundant marine alphaproteobacterium, subsists in nature at low ambient nutrient concentrations and may often be exposed to nutrient limitation, but its genome reveals no evidence of global regulatory mechanisms for adaptation to stationary phase. High-resolution capillary liquid chromatography coupled online to an LTQ mass spectrometer was used to build an accurate mass and time (AMT) tag library that

Evolutionary Relationships of “ Candidatus Endobugula” Bacterial Symbionts and Their Bugula Bryozoan Hosts

Citation
Lim-Fong et al. (2008). Applied and Environmental Microbiology 74 (11)
Names
Ca. Endobugula
Abstract
ABSTRACT Ribosomal gene sequences were obtained from bryozoans in the genus Bugula and their bacterial symbionts; analyses of host and symbiont phylogenetic trees did not support a history of strict cospeciation. Symbiont-derived compounds known to defend host larvae from predation were only detected in two out of four symbiotic Bugula species.

Intact Membrane Lipids of “ Candidatus Nitrosopumilus maritimus,” a Cultivated Representative of the Cosmopolitan Mesophilic Group I Crenarchaeota

Citation
Schouten et al. (2008). Applied and Environmental Microbiology 74 (8)
Names
Ca. Nitrosopumilus maritimus
Abstract
ABSTRACT In this study we analyzed the membrane lipid composition of “ Candidatus Nitrosopumilus maritimus,” the only cultivated representative of the cosmopolitan group I crenarchaeota and the only mesophilic isolate of the phylum Crenarchaeota . The core lipids of “ Ca . Nitrosopumilus maritimus” consisted of glycerol dialkyl glycerol tetraethers (GDGTs) with zero to four cyclopentyl moieties. Crenar
