“…Moreover, it is not only cereal crops that can be contaminated by ENNs. Other food commodities include sorghum, for which significant levels of ENNs were quantified by Oueslati et al, but also potato, apple, sugar beet, and coffee. ,,,− Altogether, the ENN occurrence data indicate that these mycotoxins can be produced on a wide variety of host plants cultivated in a wide range of pedo-climatic context, suggesting that the Fusarium species able to produce ENNs have a wide range of ecological niches and/or that the ecophysiological conditions conducive to ENN biosynthesis are broad.…”

Cereal grains and their processed food products are frequently contaminated with mycotoxins produced by the Fusarium genus. Enniatins (ENNs), which belong to the so-called "emerging mycotoxins" family, are among the most frequently found in small grain cereals. Health hazards induced by a chronic exposure to ENNs or an association of ENNs with other major mycotoxins is a risk that cannot be excluded given the current toxicological data. Thus, efforts must be pursued to define efficient control strategies to mitigate their presence in cereal grains. A key condition for achieving this aim is to gain deep and comprehensive knowledge of the factors promoting the appearance of ENNs in crop harvests. After an update of ENN occurrence data, this review surveys the scientific literature on the Fusarium species responsible for ENN contamination and covers the recent advances concerning the abiotic determinants and the genetic regulation of ENN biosynthesis.

“…In the search for new antibiotics, BEA was isolated for the first time from Beauveria bassiana as early as in 1969 [ 25 ]. BEA and ENNs are cyclic depsipeptides produced by a wide variety of Fusarium fungi, including but not limited to F. acuminatum , F. avenaceum , F. oxysporum , F. poae , F. sporotrichioides , F. sambucinum and F. tricinctum [ 26 , 27 , 28 , 29 , 30 ]. Most frequently detected mycotoxins are BEA, ENN A, A1, B and B1 ( Figure 1 ).…”

Emerging Fusarium and Alternaria mycotoxins gain more and more interest due to their frequent contamination of food and feed, although in vivo toxicity and toxicokinetic data are limited. Whereas the Fusarium mycotoxins beauvericin, moniliformin and enniatins particularly contaminate grain and grain-based products, Alternaria mycotoxins are also detected in fruits, vegetables and wines. Although contamination levels are usually low (µg/kg range), higher contamination levels of enniatins and tenuazonic acid may occasionally occur. In vitro studies suggest genotoxic effects of enniatins A, A1 and B1, beauvericin, moniliformin, alternariol, alternariol monomethyl ether, altertoxins and stemphyltoxin-III. Furthermore, in vitro studies suggest immunomodulating effects of most emerging toxins and a reproductive health hazard of alternariol, beauvericin and enniatin B. More in vivo toxicity data on the individual and combined effects of these contaminants on reproductive and immune system in both humans and animals is needed to update the risk evaluation by the European Food Safety Authority. Taking into account new occurrence data for tenuazonic acid, the complete oral bioavailability, the low total body clearance in pigs and broiler chickens and the limited toxicity data, a health risk cannot be completely excluded. Besides, some less known Alternaria toxins, especially the genotoxic altertoxins and stemphyltoxin III, should be incorporated in risk evaluation as well.

“…Various methods of ear inoculation are used in phytopathological experiments to determine genotype susceptibility to infection by Fusarium spp. [14,[36][37][38][39][40]. The current study applied the method of spraying panicles with a suspension of F. equiseti macroconidia (after Kiecana et al [33]) as it was found to be most consistent with natural infection.…”

Fusarium head blight and the contamination of cereals with toxic fungal metabolites are particularly important problems in global agriculture. The increasingly frequent isolation of F. equiseti from cereal grain and the sparse information in the literature on the harmfulness of this fungus to oat encouraged us to conduct the present research. The aim of the study was to determine the susceptibility of oat genotypes to panicle infection by F. equiseti and mycotoxin content in the grain. Field experiments involving 10 oat genotypes were conducted over three years (2015–2017). Oat panicles were inoculated with a conidial suspension of F. equiseti, which reduced the kernels yield by 38.34%, the number of kernels per panicle by 31.16% and 1000 kernels weight by 12.33%. F. equiseti accumulated type A trichothecenes (T-2 and HT-2 toxins, scirpentriol, diacetoxyscirpenol, T-2 triol, T-2 tetraol) and type B trichothecenes (deoxynivalenol, 3Ac-DON, 15Ac-DON, nivalenol, fusarenone X) in kernels at an average level of 0.0616 and 0.2035 mg·kg−1, respectively. The highest susceptibility to scabs caused by F. equiseti was found for genotype POB 4901/10, whereas cv. Elegant exhibited the highest resistance to F. equiseti in terms of yield reduction after inoculation.
