No genetic link between E. coli isolates carrying mcr-1 in bovines and humans in France

Journal of Global Antimicrobial Resistance
Background: Colistin is a last-line antibiotic used to treat severe human infections caused by carbapenemase-producing Gram-negative bacteria. In parallel, colistin has massively been used in the veterinary field so that mcr-1-positive E.

Phytophthora megakarya and Phytophthora palmivora, closely related causal agents of cacao black pod rot, underwent increases in genome sizes and gene numbers by different mechanisms [PDF]

, 2017
Phytophthora megakarya (Pmeg) and Phytophthora palmivora (Ppal) are closely related species causing cacao black pod rot. Although Ppal is a cosmopolitan pathogen, cacao is the only known host of economic importance for Pmeg.

Ribonucleases and bacterial virulence

Microbial Biotechnology, 2010
SummaryBacterial stress responses provide them the opportunity to survive hostile environments, proliferate and potentially cause diseases in humans and animals. The way in which pathogenic bacteria interact with host immune cells triggers a complicated series of events that include rapid genetic re‐programming in response to the various host ...

Probiotic‐Enhanced Porous Bio‐Hybrids with Inflammatory Targeting, ROS Scavenging, and Long‐Term Drug Release for Ulcerative Colitis Treatment

Advanced Science, EarlyView.
Probiotic‐enhanced porous bio‐hybrids (E‐xPAM@ASA), developed by coupling the drug‐loaded hairy microporous nanospheres xPAM@ASA with probiotic EcN, integrate inflammatory‐targeting, ROS scavenging, and long‐term release of 5‐ASA to improve inflammation and regulate microbiota structure in the DSS‐induced colitis model, providing an advanced strategy ...

CTX-M-15/27-positive Escherichia coli and VIM-2-producing Pseudomonas putida in free-living pigeons (Columba livia) in Tunisia

Journal of Global Antimicrobial Resistance
Objectives: Wild birds are vectors of antimicrobial resistance. Birds living in close contact with humans or other animals, like feral pigeons (Columba livia), might be especially prone to acquire resistance genes such as those encoding extended-spectrum

Protection efficacy of Argentinian isolates of Mycobacterium avium subsp. paratuberculosis with different genotypes and virulence in a murine model [PDF]

, 2018
Paratuberculosis is a chronic disease caused by Mycobacterium avium subsp. paratuberculosis (Map). The disease causes economic losses and, therefore, it is imperative to follow proper control strategies, which should include an effective vaccine. Several

Commensal Viruses Promote Intestinal Stem Cell Regeneration Following Radiation Damage by Inhibiting Hyperactivation of RIG‐I and Notch Signals

Advanced Science, EarlyView.
Ionizing radiation disrupts gut virome and bacteriome. Gut commensal viruses protect against intestinal damage and promote stem cell regeneration by inhibiting hyperactivation of RIG‐I and Notch signaling in stem cells. Fecal virome transplantation (FVT) from healthy donors can serve as a potential therapeutic intervention by enriching phages targeting

Friend and foe: factors influencing the movement of the bacterium Helicobacter pylori along the parasitism-mutualism continuum. [PDF]

, 2014
Understanding the transition of bacterial species from commensal to pathogen, or vice versa, is a key application of evolutionary theory to preventative medicine.

Quorum Sensing Inhibits Type III‐A CRISPR‐Cas System Activity Through Repressing Positive Regulators SarA and ArcR in Staphylococcus Aureus

Advanced Science, EarlyView.
This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.
