Immunocompromised patients are susceptible to several fungal infections. The genus Aspergillus can cause increased morbidity and mortality. Developing new therapies is essential understand the biology mechanisms. Fungal EVs carry important virulence factors, thus playing pivotal roles in pathophysiology. No study date has reported EV production by flavus , a fungus considered be second most common of aspergillosis relevant food contaminator found worldwide. In this study, we produced A....
Fusarium species threaten yield and quality of cereals worldwide due to their ability produce mycotoxins cause plant diseases. Trichothecenes zearalenone are the most economically significant particular concern in barley, maize wheat. For this reason, aim study was characterize isolates from brewing barley assess deoxynivalenol contamination grains. Characterization strains carried out by phylogeny based on two loci (EF-1α RPB2). Mycotoxin detection quantification were performed LC-MS. The...
Natural mycoflora and co-occurrence of fumonisins (FB1, FB2) aflatoxins (AFB1, AFB2, AFG1 AFG2) in freshly harvested corn grain samples from four regions Brazil were investigated. Fusarium verticillioides was predominant all samples. Analysis showed that 98% the contaminated with FB1 74.5% + FB2, toxin levels ranging 0.015 to 9.67 μg/g for 3.16 FB2. Twenty-one (10.5%) AFB1, seven (3.5%) AFB2 only one (0.5%) AFG2. Co-contamination observed 7% The highest contamination Nova Odessa (SP) Várzea...
Mycotoxins are widely studied by many research groups in all aspects, but the stability of these compounds needs further for clarification. The objective this study is to evaluate deoxynivalenol and zearalenone during steps malting brewing processes. levels decreased significantly production process (barley beer). During process, DON steeping, germination, (62%, 51.5%, 68%, respectively). Considering ZEN, when were compared between barley last step a significant decrease was observed. Most...
Abstract Fungi are widely disseminated in the environment and major food contaminants, colonizing plant tissues throughout production chain, from preharvest to postharvest, causing diseases. As a result, grain development seed germination affected, reducing quality nutritional value. Some fungal species can also produce mycotoxins, toxic secondary metabolites for vertebrate animals. Natural compounds, such as essential oils, have been used control diseases cereal grains due their...
The Fusarium oxysporum species complex ( FOSC ) causes disease in plants and animals, but is also widely dispersed natural ecosystems without evidence of disease. present study screened a population representing across the Australian continent for putative effector genes pisatin demethylase 1 PDA ), pectate lyase pelD) , secreted gene expression SGE xylem SIX ). pelD were prevalent isolates, was at an intermediate level, whereas detected low levels. Phylogenies these compared to EF ‐1α...
Fungal genomes encode highly organized gene clusters that underlie the production of specialized (or secondary) metabolites. Gene key functions to exploit plant hosts or environmental niches. Promiscuous exchange among species and frequent reconfigurations make some most dynamic elements fungal genomes. Despite evidence for high diversity in cluster content closely related strains, microevolutionary processes driving gain, loss, neofunctionalization are largely unknown. We analyzed Fusarium...
O milho é uma das culturas mais importantes no mundo, utilizada extensivamente para alimentação animal e consumo humano, entanto, são susceptíveis à contaminação por micotoxinas.Esses compostos produzidos cepas toxigênicas de fungos podem estar presentes solo, na água, ou transportados pelo vento.A ocorrência proliferação em grãos pode ser estimulada fatores como o maior teor umidade nos grãos, temperatura tempo armazenamento que levam redução produtividade qualidade, com perdas econômicas...
This study investigated the fungal diversity in Brazilian barley samples, focusing on Fusarium sambucinum species complex and presence of multiple mycotoxins: aflatoxins B1, B2, G1, G2 beauvericin (BEA), enniatins (ENNs) A, A1, B, deoxynivalenol (DON), fumonisins (FB) B1 HT-2 T-2 toxins, nivalenol (NIV) ochratoxin A (OTA) from two different regions, São Paulo (SP) Rio Grande do Sul (RS). The majority isolates belonged to (FSAMSC), with F. graminearum s.s. characterized as major contaminant....
This study aimed to determine the levels of fumonisins produced by F. verticillioides and FUM gene expression on Bt (Bacillus thuringiensis) non-Bt maize, post harvest, during different periods incubation. Transgenic hybrids 30F35 YG, 2B710 Hx their isogenic (30F35 2B710) were collected from field a subset 30 samples selected for experiments. Maize sterilized gamma radiation at dose 20 kGy. Samples then inoculated with Fusarium analysed under controlled conditions temperature relative...
