Eurotiales fungi are thought to be distributed worldwide but there is a paucity of information about their occurrence on diverse substrates or hosts and at specific localities. Some of the Eurotiales, including Aspergillus and Penicillium species, produce an array of secondary metabolites of use for agricultural, medicinal, and pharmaceutical applications. Here, we carried out a survey of the Eurotiales in South Korea, focusing on soil, freshwater, and plants (dried persimmon fruits and seeds of Perilla frutescens, known commonly as shiso). We obtained 11 species that-based on morphology, physiology, and multi-locus (ITS, BenA, CaM, and RPB2) phylogenetic analyses-include two new species, Aspergillus ullungdoensis sp. nov. and Penicillium jeongsukae sp. nov., and nine species that were known, but previously not described in South Korea, Aspergillus aculeatinus, Aspergillus aurantiacoflavus, Aspergillus croceiaffinis, Aspergillus pseudoviridinutans, Aspergillus uvarum, Penicillium ferraniaense, Penicillium glaucoroseum, Penicillium sajarovii, and one, Penicillium charlesii, that was isolated from previously unknown host, woodlouse (Porcellio scaber). We believe that biodiversity survey and identifying new species can contribute to set a baseline for future changes in the context of humanitarian crises such as climate change.

Objective: To evaluate the characteristics of antifungal immunity in patients with bilateral chronic rhinosinusitis with nasal polyps.

Material And Methods: The study included 74 patients with bilateral chronic rhinosinusitis with nasal polyps and a control group consisting of 30 almost healthy individuals. All patients underwent surgery and were divided into two groups: Group I - with liquid secretion (=39), Group II - with thick secretion in the paranasal sinuses (=35).

Discovery, Characterization, and Application of Broad-Spectrum Antimicrobial Peptide AtR905 from as a Biocontrol Agent.

J Agric Food Chem

December 2024

Key Laboratory of Microbial Pesticides (Ministry of Agriculture and Rural Affairs), National Biopesticide Engineering Research Centre, Hubei Biopesticide Engineering Research Centre, Hubei Academy of Agricultural Sciences, Wuhan 430064, China.

This study investigates a novel antimicrobial peptide AtR905 derived from the endophytic fungus , which was successfully expressed in , purified, and characterized, and highlighted as a promising potential biocontrol agent against various plant pathogens. The results indicated AtR905 exhibited broad-spectrum antimicrobial activities against key pathogens such as and with very low minimal inhibitory concentrations (MICs). Stability tests confirmed that AtR905 retains its antimicrobial properties under varying thermal, pH, and UV conditions.

Kojic acid is a secondary metabolite with strong chelating and antioxidant properties produced by and . Although antioxidants and chelators are important virulence factors for plant pathogens, the ecological role of kojic acid remains unclear. We previously observed a greater gene expression of antioxidants, especially kojic acid, by non-aflatoxigenic when co-cultured with aflatoxigenic Aflatoxin production was also reduced.

Biological and Chemical Management of and Ochratoxin A in Vineyards.

Toxins (Basel)

December 2024

Department of Crop Science, Laboratory of Plant Pathology, Agricultural University of Athens, Iera Odos 75, 11855 Athens, Greece.

Ochratoxin A (OTA) is a widely distributed mycotoxin and potent carcinogen produced by several fungal genera, but mainly by . Grape contamination occurs in vineyards during the period between veraison and pre-harvest, and it is the main cause of OTA's presence in wine. The aim of the current study was the evaluation of 6 chemical and 11 biological plant protection products (PPPs) and biocontrol agents in commercial vineyards of the two important Greek white wine varieties cv.

The importance of fungal pathogens in cystic fibrosis (CF) patients and their diagnosis remains a challenge, so our aim was to analyze the influence of the detection of fungi in sputum by using conventional culture and molecular techniques, polymerase chain reaction (PCR), lateral flow devices (LFDs), and galactomannan (GM) on exacerbations in patients with cystic fibrosis. A prospective study was conducted in patients via follow-up in the CF Unit of the Central University Hospital of Asturias from January 2021 to April 2022. Adult patients with at least one documented exacerbation were included.
