Smart pH‐Sensitive Indicator Films Based on Gellan Gum/Starch/Xanthan Gum With Aronia Extract: Real‐Time Tracking of Chicken Freshness

Packaging Technology and Science, EarlyView.
Intelligent indicators were composed of gellan gum, starch and xanthan gum, incorporated with anthocyanins extracted from aronia based on the solvent‐casting method. The films demonstrated remarkable antibacterial activity against Staphylococcus aureus and Escherichia coli. The aronia‐added films were sensitive at varying pHs.

Porcine Clostridium perfringens type A spores, enterotoxin and antibody to enterotoxin

Veterinary Record, 1989
Forty-two Clostridium perfringens type A strains isolated from cases of diarrhoea in pigs were tested for their ability to sporulate and produce enterotoxin in three different sporulation media. Enterotoxin was produced by 11 of the 42 C perfringens type A isolates (26.2 per cent).

Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

Allergy, EarlyView.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.

Virulence Factors and Phylogeny of Staphylococcus aureus Associated With Bovine Mastitis in Russia Based on Genome Sequences

Frontiers in Veterinary Science, 2020
Staphylococcus aureus is a causative agent of different infectious processes, food poisoning, and autoimmune disorders. The horizontal transfer of pathogenic strains can occur from animal to human under both house and farm conditions, and the spread of ...

Staphylococcal Enterotoxin Superantigens

Experimental Biology and Medicine, 1991
Staphylococcal enterotoxins (SE) are a family of structurally related proteins that are produced by Staphylococcus aureus. They play a role in the pathogenesis of food poisoning and are the most potent activators of T lymphocytes known. The receptors for SE on antigen-presenting cells are major histocompatibility complex class II molecules.

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, EarlyView.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Microbe‐responsive human γδ T cells: the peculiar case of Staphylococcus aureus

Immunology &Cell Biology, EarlyView.
Human Vγ9/Vδ2 T cells display a unique responsiveness towards microbial organisms producing the metabolite HMB‐PP. However, Staphylococcus aureus does not possess HMB‐PP but can induce activation, cytokine expression and proliferation of Vγ9/Vδ2 T cells regardless. We here discuss potential pathways, ligands and biological functions in this response to

Binding to The Target Cell Surface Is The Crucial Step in Pore Formation of Hemolysin BL from Bacillus cereus

Toxins, 2019
A major virulence factor involved in Bacillus cereus food poisoning is the three-component enterotoxin hemolysin BL. It consists of the binding component B and the two lytic components L1 and L2.

Understanding the rationale for metronidazole use in dogs and cats

Journal of Small Animal Practice, EarlyView.
Objective It is currently unknown how often antibiotics (including metronidazole) are used for non‐antibacterial purposes in dogs and cats. This study looked to characterise the rationale for metronidazole prescription in these species. Methods Retrospective cohort study.
