Preliminary landscape of Candidatus Saccharibacteria in the human microbiome

Citation

Names
Ca. Saccharibacteria
Abstract
IntroductionCandidate Phyla Radiation (CPR) and more specifically Candidatus Saccharibacteria (TM7) have now been established as ubiquitous members of the human oral microbiota. Additionally, CPR have been reported in the gastrointestinal and urogenital tracts. However, the exploration of new human niches has been limited to date.MethodsIn this study, we performed a prospective and retrospective screening of TM7 in human samples using standard PCR, real-time PCR, scanning electron microscopy (SE

Candidatus Alkanophaga archaea from Guaymas Basin hydrothermal vent sediment oxidize petroleum alkanes

Abstract
AbstractMethanogenic and methanotrophic archaea produce and consume the greenhouse gas methane, respectively, using the reversible enzyme methyl-coenzyme M reductase (Mcr). Recently, Mcr variants that can activate multicarbon alkanes have been recovered from archaeal enrichment cultures. These enzymes, called alkyl-coenzyme M reductase (Acrs), are widespread in the environment but remain poorly understood. Here we produced anoxic cultures degrading mid-chain petroleum n-alkanes between pentane (

Nuevos haplotipos de Diaphorina citri, vector de Candidatus Liberibacter en zonas citrícolas de México

Citation
Ceballos Ceballos et al. (2022). Revista Mexicana de Ciencias Agrícolas 13 (8)
Names
Liberibacter
Abstract
Se identificaron nuevos haplotipos de Diaphorina citri también conocido como el psílido asiático de los cítricos, denominados DcitACC-1, DcitACC-2 y DcitACC-3. Los estudios se basaron en la amplificación de ADN del gen COI mitocondrial y se utilizaron individuos de diferentes zonas citrícolas del país, en algunas zonas productoras del país no se han realizado muestreos con anterioridad, específicamente en los municipios de Acatlán de Pérez, Oaxaca, Misantla y Tantoyuca, Veracruz y Huejutla, Hida

Identificación de proteínas en Candidatus Liberibacter asiaticus para desarrollar un método de detección inmunoenzimático

Citation
Rodríguez-Quibrera et al. (2022). Revista Mexicana de Ciencias Agrícolas 13 (8)
Names
Ca. Liberibacter asiaticus
Abstract
El objetivo de este trabajo fue identificar en el genoma de Candidatus Liberibacter asiaticus (CLas), proteínas de membrana externa con potencial para el desarrollo y optimización de un método de detección inmunoenzimático. El estudio se realizó durante 2019 y se utilizó el servidor web Predict Protein, así como las bases de datos HhPred/HhSearch y Pfam. Se detectaron 52 proteínas de membrana externa en el genoma completo de CLas, de las cuales, 11 no habían sido caracterizadas previamente. Los

SeqCode: a nomenclatural code for prokaryotes described from sequence data

Citation
Hedlund et al. (2022). Nature Microbiology
Names
Kryptoniales Kryptoniia Kryptoniaceae Kryptonium mobile
Abstract
AbstractMost prokaryotes are not available as pure cultures and therefore ineligible for naming under the rules and recommendations of the International Code of Nomenclature of Prokaryotes (ICNP). Here we summarize the development of the SeqCode, a code of nomenclature under which genome sequences serve as nomenclatural types. This code enables valid publication of names of prokaryotes based upon isolate genome, metagenome-assembled genome or single-amplified genome sequences. Otherwise, it is s

A closed Candidatus Odinarchaeum chromosome exposes Asgard archaeal viruses

Citation
Tamarit et al. (2022). Nature Microbiology 7 (7)
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

Candidatus Thiovulum sp. strain imperiosus: the largest free-living Epsilonproteobacteraeota Thiovulum strain lives in a marine mangrove environment

Names
Ca. Thiovulum imperiosus
Abstract
A large (47.75 ± 3.56 µm in diameter) Thiovulum bacterial strain forming white veils is described from a marine mangrove ecosystem. High sulfide concentrations (up to 8 mM of H2S) were measured on sunken organic matter (wood/bone debris) under laboratory conditions. This sulfur-oxidizing bacterium colonized the organic matter, forming a white veil. According to conventional scanning electron microscope (SEM) observations, bacterial cells are ovoid and slightly motile by numerous small flagella
