Candidatus Uabimicrobium helgolandensis”—a planctomycetal bacterium with phagocytosis-like prey cell engulfment, surface-dependent motility, and cell division

Abstract
ABSTRACT The unique cell biology presented by members of the phylum Planctomycetota has puzzled researchers ever since their discovery. Initially thought to have eukaryotic-like features, their traits are now recognized as exceptional but distinctly bacterial. However, recently discovered strains again added novel and stunning aspects to the planctomycetal cell biology—shapeshifting by members of the “ S

Abstract
ABSTRACT The microbial communities of marine seep sediments contain unexplored physiological and phylogenetic diversity. Here, we examined 30 bacterial metagenome-assembled genomes (MAGs) from cold seeps in the South China Sea, the Indian Ocean, the Scotian Basin, and the Gulf of Mexico, as well as from deep-sea hydrothermal sediments in the Guaymas Basin, Gulf of California. Phylogenetic analyses of these MAGs indicate that they form a distinct

Abstract
ABSTRACT Bacterial endosymbionts of eukaryotic hosts typically experience massive genome reduction, but the underlying evolutionary processes are often obscured by the lack of free-living relatives. Endomicrobia, a family-level lineage of host-associated bacteria in the phylum Elusimicrobiota that comprises both free-living representatives and endosymbionts of termite gut flagellates, are an excellent model to study e

Microscopic and metatranscriptomic analyses revealed unique cross-domain parasitism between phylum Candidatus Patescibacteria/candidate phyla radiation and methanogenic archaea in anaerobic ecosystems

Abstract
ABSTRACT To verify whether members of the phylum Candidatus Patescibacteria parasitize archaea, we applied cultivation, microscopy, metatranscriptomic, and protein structure prediction analyses on the Patescibacteria-enriched cultures derived from a methanogenic bioreactor. Amendment of cultures with exogenous methanogenic archaea, acetate, amino acids, and nucleoside monophosphates increased the relative abundance of

Symbiosis between Candidatus Patescibacteria and Archaea Discovered in Wastewater-Treating Bioreactors

Names
Ca. Patescibacteria
Abstract
One highly diverse phylogenetic group of Bacteria, Ca . Patescibacteria, remains poorly understood, but, from the few cultured representatives and metagenomic investigations, they are thought to live symbiotically or parasitically with other bacteria or even with eukarya.

Comparative Genomics on Cultivated and Uncultivated Freshwater and Marine “ Candidatus Manganitrophaceae” Species Implies Their Worldwide Reach in Manganese Chemolithoautotrophy

Citation
Yu et al. (2022). mBio 13 (2)
Names
Ca. Manganitrophaceae
Abstract
Manganese (Mn) is an abundant redox-active metal that cycles in many of Earth’s biomes. While diverse bacteria and archaea have been demonstrated to respire Mn(III/IV), only recently have bacteria been implicated in Mn(II) oxidation-dependent growth.

Characterization of the First Cultured Representative of “ Candidatus Thermofonsia” Clade 2 within Chloroflexi Reveals Its Phototrophic Lifestyle

Citation
Zheng et al. (2022). mBio 13 (2)

Abstract
The deep ocean microbiota represents the unexplored majority of global ocean waters. The phylum Chloroflexi is abundant and broadly distributed in various deep-sea ecosystems.

A New Model Trypanosomatid, Novymonas esmeraldas : Genomic Perception of Its “ Candidatus Pandoraea novymonadis” Endosymbiont

Citation
Zakharova et al. (2021). mBio 12 (4)
Names
Ca. Pandoraea novymonadis
Abstract
Novymonas esmeraldas is a parasitic flagellate of the family Trypanosomatidae representing the closest insect-restricted relative of the human pathogen Leishmania . It bears symbiotic bacteria in its cytoplasm, the relationship with which has been established relatively recently and independently from other known endosymbioses in protists.

Modeling the Life Cycle of the Intramitochondrial Bacterium “ Candidatus Midichloria mitochondrii” Using Electron Microscopy Data

Citation
Comandatore et al. (2021). mBio 12 (3)
Names
Ca. Midichloria mitochondrii
Abstract
Our results suggest that Midichloria mitochondrii , the intramitochondrial bacterium, does not invade mitochondria like predatory bacteria do but instead moves from mitochondrion to mitochondrion within the oocytes of Ixodes ricinus . A better understanding of the lifestyle of M. mitochondrii will allow us to better define the role of this bacterial symbiont in the host physiology.
