Toxins, 2021 Staphylococcal enterotoxin type B (SEB) is associated with food poisoning. Current methods for the detection of biologically active SEB rely upon its ability to cause emesis when administered to live kittens or monkeys.

Coexistence of Competing Microbial Strains under Twofold Environmental Variability and Demographic Fluctuations [PDF]
New J. Phys 25, 123010 (2023), 2023 Microbial populations generally evolve in volatile environments, under conditions fluctuating between harsh and mild, e.g. as the result of sudden changes in toxin concentration or nutrient abundance. Environmental variability thus shapes the long-time population dynamics, notably by influencing the ability of different strains of microorganisms to ...

Octyl Gallate Use to Protect Seeds from Foodborne Fungal Pathogens
Biology and Life Sciences Forum, 2022 There is limited efficacy with conventional seed sanitation methods, directly affecting food safety. Insufficient elimination of mycotoxin-producing fungi contaminating seed surfaces can result in high mycotoxin contamination.

Toxin-mediated competition in weakly motile bacteria [PDF]
2019, J. Theor. Biol. 480 , 205-217, 2019 Many bacterial species produce toxins that inhibit their competitors. We model this phenomenon by extending classic two-species Lotka-Volterra competition in one spatial dimension to incorporate toxin production by one species. Considering solutions comprising two adjacent single-species colonies, we show how the toxin inhibits the susceptible species ...

Using Multiscale Molecular Dynamics Simulations to Obtain Insights into Pore Forming Toxin Mechanisms [PDF]
Methods in Enzymology (Chapter Sixteen), 2021, 2020 Pore forming toxins (PFTs) are virulent proteins released by several species, including many strains of bacteria, to attack and kill host cells. In this article, we focus on the utility of molecular dynamics (MD) simulations and the molecular insights gleaned from these techniques on the pore forming pathways of PFTs.

Indian Journal of Dermatology, 2010 Botulinum toxin, one of the most poisonous biological substances known, is a neurotoxin produced by the bacterium Clostridium botulinum. C. botulinum elaborates eight antigenically distinguishable exotoxins (A, B, C(1), C(2), D, E, F and G). All serotypes interfere with neural transmission by blocking the release of acetylcholine, the principal ...

Cinnamic Acid Analogs as Intervention Catalysts for Overcoming Antifungal Tolerance
Molecules, 2017 Disruption of fungal cell wall should be an effective intervention strategy. However, the cell wall-disrupting echinocandin drugs, such as caspofungin (CAS), cannot exterminate filamentous fungal pathogens during treatment.
