Identification of housekeeping genes of Candidatus Branchiomonas cysticola associated with epitheliocystis in Atlantic salmon (Salmo salar L.)

Names
Ca. Branchiomonas cystocola
Abstract
AbstractCandidatus Branchiomonas cysticola is an intracellular, gram-negative Betaproteobacteria causing epitheliocystis in Atlantic Salmon (Salmo salar L.). The bacterium has not been genetically characterized at the intraspecific level despite its high prevalence among salmon suffering from gill disease in Norwegian aquaculture. DNA from gill samples of Atlantic salmon PCR positive for Cand. B. cysticola and displaying pathological signs of gill disease, was, therefore, extracted and subject t

Reevaluation of the Phylogenetic Diversity and Global Distribution of the Genus “CandidatusAccumulibacter”

Abstract
“CandidatusAccumulibacter” is the most studied PAO, with a primary role in biological nutrient removal. However, the species-level taxonomy of this lineage is convoluted due to the use of different phylogenetic markers or genome sequencing approaches. Here, we redefined the phylogeny of these organisms, proposing a comprehensive approach which could be used to address the classification of other diverse and uncultivated lineages.

A closed Candidatus Odinarchaeum chromosome exposes Asgard archaeal viruses

Names
Ca. Odinarchaeum yellowstonii
Abstract
AbstractAsgard archaea have recently been identified as the closest archaeal relatives of eukaryotes. Their ecology, and particularly their virome, remain enigmatic. We reassembled and closed the chromosome of Candidatus Odinarchaeum yellowstonii LCB_4, through long-range PCR, revealing CRISPR spacers targeting viral contigs. We found related viruses in the genomes of diverse prokaryotes from geothermal environments, including other Asgard archaea. These viruses open research avenues into the ec

Complete Genome Sequence of “ Candidatus Nanosynbacter” Strain HMT-348_TM7c-JB, a Member of Saccharibacteria Clade G1

Citation
Baker (2022). Microbiology Resource Announcements 11 (5)
Names
Ca. Nanosynbacter
Abstract
Saccharibacteria are abundant and diverse members of the human oral microbiome; however, they are poorly understood and appear to exhibit an epibiont/parasitic lifestyle dependent on host bacteria. Here, a complete metagenome-assembled genome (MAG) sequence of an organism from Saccharibacteria clade G1 human microbial taxon (HMT) 348 is reported, strain HMT-348_TM7c-JB.

A New Gene Family Diagnostic for Intracellular Biomineralization of Amorphous Ca Carbonates by Cyanobacteria

“Synechococcus calcipolaris”
Abstract
Abstract Cyanobacteria have massively contributed to carbonate deposition over the geological history. They are traditionally thought to biomineralize CaCO3 extracellularly as an indirect byproduct of photosynthesis. However, the recent discovery of freshwater cyanobacteria-forming intracellular amorphous calcium carbonates (iACC) challenges this view. Despite the geochemical interest of such a biomineralization process, its molecular mechanisms and evolutionary history remain elu

Complete Genome Sequence of Human Oral Saccharibacterium “ Candidatus Nanosynbacter sp. HMT352” Strain KC1

Citation
Cross et al. (2022). Microbiology Resource Announcements 11 (2)
Names
Ca. Nanosynbacter
Abstract
“Cand. Nanosynbacter sp. HMT352” strain KC1 is an ectoparasitic saccharibacterium/TM7 that was co-isolated from a human saliva sample with its obligate bacterial host, Schaalia odontolytica . The genome of strain KC1 enables studies of the mechanisms and evolution of interspecies interactions and, for oral species, studies of their potential roles in health and disease.

Genome Sequence of a New “ Candidatus ” Phylum “Dependentiae” Isolate from Chiba, Japan

Names
Ca. Dependentiae
Abstract
Little is known about the bacterial phylum “ Candidatus Dependentiae,” because only three isolates have been reported. Here, I report the isolation and genome sequencing of a new member of this phylum, strain Noda2021. This is the fourth strain isolated from the phylum “ Candidatus Dependentiae.”
