Frontiers in Cellular and Infection MicrobiologyBackgroundArginine contributes to host defense by serving as a substrate for inducible nitric oxide synthase (iNOS) to produce antimicrobial nitric oxide (NO). However, how bacterial pathogens respond to host arginine metabolism remains poorly understood.

The Role of Essential Oils against Pathogenic Escherichia coli in Food Products
Microorganisms, 2020 Outbreaks related to foodborne diseases are a major concern among health authorities, food industries, and the general public. Escherichia coli (E. coli) is a pathogen associated with causing multiple outbreaks in the last decades linked to several ready

Electricity network regulation in the EU : The challenges ahead for transmission and distribution
, 2018 The UK model of incentive regulation of power grids was at one time the most advanced, and elements of it were adopted throughout the EU. This model worked well, particularly in the context of limited investment and innovation, a single and strong ...

Within-Host Dynamics of Multi-Species Infections:Facilitation, Competition and Virulence [PDF]
, 2012 Host individuals are often infected with more than one parasite species (parasites defined broadly, to include viruses and bacteria). Yet, research in infection biology is dominated by studies on single-parasite infections.

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila
Advanced Science, EarlyView.While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

Studies on the structure, lipid modification and interactions of the virulence-associated proteins of rhodococcus equi [PDF]
, 2014 Rhodococcus equi is a Gram-positive soil organism that causes an aggressive bronchopneumonia in foals and opportunistic infections in immuno-compromised humans.

Advanced Science, EarlyView.This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Heterogeneity in ess transcriptional organization and variable contribution of the Ess/Type VII protein secretion system to virulence across closely related Staphylocccus aureus strains [PDF]
, 2014 The Type VII protein secretion system, found in Gram-positive bacteria, secretes small proteins, containing a conserved W-x-G amino acid sequence motif, to the growth medium.

Advanced Science, EarlyView.A programmable encapsulation technology is developed to reduce bacterial immunogenicity and proliferation after systemic administration. The cross‐linked polymer networks around individual bacteria enable immunogenic shielding and permit selective proliferation in tumors, allowing the bacteria to convert tumor‐accumulated ammonia into L‐arginine and ...
