The synthesis and function of the alarmone (p)ppGpp in firmicutes

International Journal of Medical Microbiology, 2010
In most bacteria, nutrient limitations provoke the stringent control by the rapid synthesis of the alarmones pppGpp and ppGpp. The most prominent and highly conserved reaction is the repression of rRNA synthesis. Additionally, (p)ppGpp synthesis is also linked to many other physiological changes involving gene activation/repression but also protein ...

Corrigendum: ‘A comparative genome analysis of the Bacillota (Firmicutes) class Dehalobacteriia’

Microbial Genomics, 2023
In the published version of the article, Dr Julian Zaugg was omitted as a co-author, and now has been added as an author in fifth position. His contributions to the manuscript (implementation of bioinformatics pipelines used for functional inference and proteomics analysis) occurred very early during the project and consequently he was inadvertently ...

Evidence for shared ancestry between Actinobacteria and Firmicutes bacteriophages

Peer Community Journal, 2021
Bacteriophages typically infect a small set of related bacterial strains. The transfer of bacteriophages between more distant clades of bacteria has often been postulated, but remains mostly unaddressed. In this work we leverage the sequencing of a novel

Discovery of a new family of relaxases in Firmicutes bacteria

PLOS Genetics, 2017
Antibiotic resistance is a serious global problem. Antibiotic resistance genes (ARG), which are widespread in environmental bacteria, can be transferred to pathogenic bacteria via horizontal gene transfer (HGT). Gut microbiomes are especially apt for the emergence and dissemination of ARG.

Highly diverse nirK genes comprise two major clades that harbour ammonium-producing denitrifiers [PDF]

, 2016
Background: Copper dependent nitrite reductase, NirK, catalyses the key step in denitrification, i.e. nitrite reduction to nitric oxide. Distinct structural NirK classes and phylogenetic clades of NirK-type denitrifiers have previously been observed ...

Mixed Spices at Culinary Doses Have Prebiotic Effects in Healthy Adults: A Pilot Study. [PDF]

, 2019
Spices were used as food preservatives prior to the advent of refrigeration, suggesting the possibility of effects on microbiota. Previous studies have shown prebiotic activities in animals and in vitro, but there has not been a demonstration of ...

Evaluating the capacity of human gut microorganisms to colonize the zebrafish larvae (Danio rerio) [PDF]

, 2018
Indexación: Scopus.In this study we evaluated if zebrafish larvae can be colonized by human gut microorganisms. We tested two strategies: (1) through transplantation of a human fecal microbiota and (2) by successively transplanting aerotolerant anaerobic

Firmicutes/Bacteroidetes and Firmicutes/Proteobacteria ratios are associated with worse prognosis in a cohort of Latin American patients with cirrhosis

Clinics
Some evidence suggests an association between gut dysbiosis and cirrhosis progression. The authors investigated Gut Microbiome (GM) influence on 90-day mortality and hospitalization/rehospitalization rates in cirrhotic patients.Compensated/decompensated outpatients and decompensated inpatients were prospectively included and compared to healthy ...
