First Global Report of Plasmid-Mediated mcr-1 and Extended-Spectrum Beta-Lactamase-Producing Escherichia coli from Sheep in Portugal

Antibiotics, 2021
Resistances to extended-spectrum cephalosporins (ESC) and colistin are One Health issues since genes encoding these resistances can be transmitted between all sectors of the One Health concept, i.e., human, animal, and the environment.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Anthropisation et maladies à tique : l’exemple de la borréliose de Lyme

Comptes Rendus Biologies, 2023
Ticks and tick-borne diseases are on the rise throughout the world. The reasons are multifactorial but all associated with human practices, including climate change and socio-economic and eco systemic changes. In the northern hemisphere, Lyme borreliosis

The influence of the accessory genome on bacterial pathogen evolution [PDF]

, 2011
Bacterial pathogens exhibit significant variation in their genomic content of virulence factors. This reflects the abundance of strategies pathogens evolved to infect host organisms by suppressing host immunity.

Bacteriocins, spite and virulence [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004
There has been much interest in using social evolution theory to predict the damage to a host from parasite infection, termed parasite virulence. Most of this work has focused on how high kinship between the parasites infecting a host can select for more prudent exploitation of the host, leading to a negative relationship between virulence and parasite

Protein O‐glycosylation in the Bacteroidota phylum

FEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

Activation of the Listeria monocytogenes Virulence Program by a Reducing Environment. [PDF]

, 2017
Upon entry into the host cell cytosol, the facultative intracellular pathogen Listeria monocytogenes coordinates the expression of numerous essential virulence factors by allosteric binding of glutathione (GSH) to the Crp-Fnr family transcriptional ...

Limitation of Screening of Different Variants of SARS-CoV-2 by RT-PCR

Diagnostics, 2021
Since January 2021, the diffusion of the most propagated SARS-CoV-2 variants in France (UK variant 20I/501Y.V1 (lineage B.1.1.7), 20H/H501Y.V2 (lineage B.1.351) and 20J/H501Y.V3 (lineage P.1)) were urgently screened, needing a surveillance with an RT-PCR

Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

FEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...
