FUSARIUM MUSAE AND FUSARIUM VERTICILLIOIDES CROSS-KINGDOM PATHOGENS: GENOMICS AND DIAGNOSTIC INNOVATION
… fungi that include major plant pathogens, food contaminants, and opportunistic human pathogens. Among them, transkingdom species capable of infecting both plants and humans represent an emerging challenge within the One Health framework. Fusarium musae exemplifies this dual ecological …

Fundamental study of natural and synthetic antimicrobial peptides as novel preservatives against fungal food spoilage
A large part of food loss is associated with the development of fungal contamination at early or late stages of production. This spoilage, via the production of mycotoxins, has potentially disastrous consequences on consumers’ health. The overuse of chemical antimicrobials in foods (e.g., sorbates) …
