Influence of B cells in liver fibrosis associated with hepatitis B virus harboring basal core promoter mutations [PDF]

, 2012
The development of the liver disease in chronic hepatitis B with common viral variants can be determined through the interaction between the virus and the host immune response.

Beyond “you are what you eat”: Unlocking gut microbiota‐mediated biotransformation of dietary phytochemicals

iMetaOmics, EarlyView.
The “efficacy paradox” of phytochemicals, low bioavailability yet significant health benefits, is associated with gut microbiota, which biotransforms dietary precursors into bioactive metabolites, enabling systemic effects. Thus, health outcomes of diet depend not just on intake “the rainbow”, but on gut microbial metabolism, redefining “you are what ...

Occurrence of antibiotic-resistant bacterial strains isolated in poultry

Veterinární Medicína, 2002
The main goal of the study was to analyse the occurrence of antibiotic-resistant bacterial strains in poultry in the Czech Republic in 1999-2000. The resistance was determined in 128 selected Escherichia coli, 88 Staphylococcus sp.

Proteomic characterization of persisters in Enterococcus faecium

BMC Microbiology
Abstract Background Enterococcus faecium is a Gram-positive bacterium, naturally present in the human intestinal microbiota, but is also an opportunistic pathogen responsible for healthcare-associated infections. Persisters are individuals of a subpopulation able to survive by arrest of growth coping with conditions that

Epidemic and Nonepidemic Multidrug-ResistantEnterococcus faecium [PDF]

Emerging Infectious Diseases, 2003
The epidemiology of vancomycin-resistant Entero- coccus faecium (VREF) in Europe is characterized by a large community reservoir. In contrast, nosocomial outbreaks and infections (without a community reservoir) characterize VREF in the United States.

L‐EasyARG: A long‐read metagenomics tool for rapid antibiotic‐resistance‐gene profiling

iMetaOmics, EarlyView.
L‐EasyARG is a pipeline for long‐read metagenomic profiling of antibiotic resistance genes (ARGs) and their genetic context. It integrates ARG identification, plasmid and mobile genetic element (MGE) detection, taxonomic classification, and further identifies ARGs carried by human bacterial pathogens (HBPs) defined in the WHO and ESKAPE pathogen lists.

Microbial keystone taxa and metabolic signatures in centenarians regulate intestinal homeostasis during aging

iMeta, EarlyView.
Clostridium scindens and its metabolite indole‐3‐acetic acid (IAA) are identified as a keystone taxon and metabolic signature in centenarians. Clostridium scindens enhances microbial network stability and produces IAA via its own amidase (AMIE) and aldehyde dehydrogenase (ALDH), thus promoting intestinal homeostasis by activating the aryl hydrocarbon ...
