Analysis of Additional Virulence Genes and Virulence Gene Regions in Listeria monocytogenes Confirms the Epidemiologic Relevance of Multi-Virulence-Locus Sequence Typing

open access: yesJournal of Food Protection, 2008
Previous molecular subtyping studies have defined four epidemic clones (ECs) of Listeria monocytogenes (ECI, ECII, ECIII, and ECIV). Partial sequences of eight virulence genes were previously shown to be identical within individual ECs of L. monocytogenes.

Evolution of linked avirulence effectors in Leptosphaeria maculans is affected by genomic environment and exposure to resistance genes in host plants

open access: yes, 2010
Brassica napus (canola) cultivars and isolates of the blackleg fungus, Leptosphaeria maculans interact in a ‘gene for gene’ manner whereby plant resistance (R) genes are complementary to pathogen avirulence (Avr) genes.

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

open access: yes, 2014
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.

A Dual‐Functional Biohybrid Nanorobot to Synergistically Eradicate Biofilm and Degrade Antibiotic Resistance Genes

open access: yesAdvanced Science, EarlyView.
A biohybrid nanorobot integrating lytic bacteriophage N4 with Pd nanozymes is developed for targeted eradication of multidrug‐resistant E. coli biofilms. Synergistic bacterial lysis and ROS‐mediated oxidation enable simultaneous biofilm removal and antibiotic resistance genes degradation, maintaining high efficacy in complex wastewater environments ...

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

open access: yesPLoS 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 ...

The ability to utilize mucin affects the regulation of virulence gene expression in Streptococcus pneumoniae.

open access: yes, 2008
Streptococcus pneumoniae colonizes the mucin-rich environment of the nasopharynx. As colonization may be the first stage of infection, investigation was carried out as to whether the pneumococcus could utilize mucin as a source of nutrient and whether ...

Predicting the virulence of MRSA from its genome sequence [PDF]

open access: yes, 2014
This work is supported by the EC-FP7 program no. 245500 and the BBSRCMicrobial virulence is a complex and often multifactorial phenotype, intricately linked to a pathogen's evolutionary trajectory.

Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

open access: yesAdvanced Science, EarlyView.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

MOLECULAR IDENTIFICATION OF Aeromonas hydrophila STRAINS RECOVERED FROM KAFRELSHEIKH FISH FARMS

open access: yesSlovenian 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 ...
