Epipolythiodioxopiperazine‐Based Natural Products: Building Blocks, Biosynthesis and Biological Activities

open access: yesChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Housing sulfur: Certain fungi produce diketopiperazine compounds with a transannular sulfur bridge. These so‐called epipolythiodioxopiperzines are toxic by non‐specifically interacting with intracellular proteins and contribute to fungal pathogenicity. Producer strains serve as bio‐pesticides but also question safety of food fermentation.

pH‐Responsive AIE Photosensitizers for Enhanced Antibacterial Therapy

open access: yesAngewandte Chemie, EarlyView.
This study develops DHTPA, a NIR fluorescent, pH‐responsive AIE photosensitizer that enhances photodynamic therapy for bacterial infections by promoting ROS generation in acidic environments, demonstrating effective antibacterial activity and accelerated wound healing in vitro and in vivo.

Analysis of Pseudomonas aeruginosa Virulence in Dictyostelium discoideum Strains [PDF]

open access: yesarXiv, 2018
Dictyostelium discoideum is an ideal organism to test the pathogenicity of Pseudomonas aeruginosa, since its eukaryote nature allows for comparisons to be made to human health. Additionally, D. discoideum naturally feeds on bacteria and has a simplistic genome which improves result interpretation. P.

Strategic use of virulence pattern to develop genetic markers for resistance to common bunt (Tilletia caries) in wheat [PDF]

open access: yes, 2018
When assesssing races of common bunt for virulens pattern within a region, it is important to take into account that collected spores may represent a diverse population of different virulence races.

Identification of the long polar fimbriae gene variants in the locus of enterocyte effacement-negative Shiga toxin-producing Escherichia coli strains isolated from humans and cattle in Argentina [PDF]

open access: yes, 2010
The long polar fimbriae (Lpf) is one of few adhesive factors of Shiga toxin-producing Escherichia coli (STEC) and it is associated with colonization of the intestine. Studies have demonstrated the presence of lpf genes in several pathogenic E.

Investigating Social Immunity in Swarming Locusts via a Triple Animal–Robot–Pathogen Hybrid Interaction

open access: yesAdvanced Intelligent Systems, EarlyView.
This study explores social immunity in gregarious locusts using a groundbreaking animal–robot–pathogen interaction model. By comparing locust responses to biomimetic agents mimicking healthy and infected individuals, significant behavioral changes are revealed.

Antimicrobial Usages and Antimicrobial Resistance in Commensal Escherichia coli From Veal Calves in France: Evolution During the Fattening Process

open access: yesFrontiers in Microbiology, 2019
Extended-Spectrum-Cephalosporin (ESC)-resistant Enterobacteriaceae have widely spread in all settings worldwide. In animals, Extended-Spectrum Beta-Lactamase (ESBL) producers have been frequently identified in veal calves.

Characterizing virulence differences in a parasitoid wasp through comparative transcriptomic and proteomic [PDF]

open access: yesarXiv
Background: Two strains of the endoparasitoid Cotesia typhae present a differential parasitism success on the host, Sesamia nonagrioides. One is virulent on both permissive and resistant host populations, and the other only on the permissive host. This interaction provides a very interesting frame for studying virulence factors.
