Occurrence of virulence genes in multidrug-resistant Escherichia coli isolates from humans, animals, and the environment: One health perspective.

PLoS ONE
Escherichia coli is one of the critical One Health pathogens due to its vast array of virulence and antimicrobial resistance genes. This study used multiplex PCR to determine the occurrence of virulence genes bfp, ompA, traT, eaeA, and stx1 among 50 ...

Distribution of Virulence Factors in Vancomycin-Resistant Enterococci Isolated from Clinical and Intestinal Samples

Microorganisms
Virulence factors in enterococci play an important role in the pathogenesis of enterococcal infection and colonization. The aim was to determine the prevalence of genes encoding virulence factors in VRE from clinical and intestinal samples.

Genomic variations associated with attenuation in Mycobacterium avium subsp paratuberculosis vaccine strains [PDF]

, 2013
BACKGROUND: Mycobacterium avium subspecies paratuberculosis (MAP) whole cell vaccines have been widely used tools in the control of Johne's disease in animals despite being unable to provide complete protection. Current vaccine strains derive from stocks

Ionic–Bionic Interfaces: Advancing Iontronic Strategies for Bioelectronic Sensing and Therapy

Advanced Science, EarlyView.
Ionic–bionic interfaces for bioelectronics leverage ions as multifunctional mediators that combine mechanical compliance, ionic and electronic functionalities, and therapeutic effects. These systems offer real‐time biosignal transduction, effective wound dressing, responsive drug delivery, and seamless interaction between soft tissues and electronic ...

MOLECULAR IDENTIFICATION OF Aeromonas hydrophila STRAINS RECOVERED FROM KAFRELSHEIKH FISH FARMS

Slovenian Veterinary Research, 2019
The aim of this study was to recover Aeromonas hydrophila from Kafrelsheikh tilapia (Oreochromis niloticus) farms and to study its virulence. Adult fish (n = 100) exhibiting the onset of clinical signs were bacteriologically examined using aeromonas ...

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Bistable Expression of Virulence Genes in Salmonella Leads to the Formation of an Antibiotic-Tolerant Subpopulation

PLoS Biology, 2014
The bistable expression of virulence genes in Salmonella allows a clonal population to hedge its bets: one subpopulation suffers a growth cost, but is tolerant to antibiotics.

Genome‐Wide Codon Reprogramming Enables a Multifactorially Attenuated Influenza Vaccine with Broad Cross‐Protection

Advanced Science, EarlyView.
Genome‐wide codon reprogramming of influenza A virus introduces 1956 synonymous mutations across five segments and elevates CpG content, causing defective NA packaging, loss of NS1 accumulation, and enhanced ZAP‐mediated antiviral responses without affecting RNA or protein synthesis. These mechanisms result in profound attenuation and potent homologous

The PAS domain-containing histidine kinase RpfS is a second sensor for the diffusible signal factor of Xanthomonas campestris [PDF]

, 2014
Summary: A cell-cell signalling system mediated by the fatty acid signal DSF controls the virulence of Xanthomonas campestris pv. campestris (Xcc) to plants. The synthesis and recognition of the DSF signal depends upon different Rpf proteins.
