“…To date, 27 enniatins have been described and isolated from different fungal species (Lin et al 2002;Nilanonta et al 2003). They can act as ionophores and exhibit insecticidal, antimicrobial, cytotoxic and phytotoxic activities (Gäumann et al 1960;Grove and Pople 1980;Ovchinnikov et al 1974;Uhlig et al 2004;Vesonder and Golinski 1989). In New Zealand, one F. avenaceum isolate and two F. culmorum isolates produced uncharacterised enniatins in detectable concentrations (Bosch et al 1989), whereas relatively high amounts were produced by all of the Western Australian F. acuminatum, F. avenaceum and F. tricinctum isolates, and one F. sambucinum isolate from pasture species.…”

Mycotoxins produced by Fusarium species associated with annual legume pastures and ‘sheep feed refusal disorders’ in Western Australia

Sheep grazing in Western Australia can partially or completely refuse to consume annual Medicago pods contaminated with a number of different Fusarium species. Many Fusarium species are known to produce trichothecenes as part of their array of toxigenic secondary metabolites, which are known to cause feed refusal in animals. This study reports the identity of Fusarium species using species-specific PCR primers and a characterization of the toxigenic secondary metabolites produced by 24 Fusarium isolates associated with annual legume-based pastures and particularly those associated with sheep feed refusal disorders in Western Australia. Purification of the fungal extracts was facilitated by a bioassay-guided fractionation using brine shrimp. A number of trichothecenes (3-acetyldeoxynivalenol, deoxynivalenol, fusarenon-X, monoacetoxyscirpenols, diacetoxyscirpenol, scirpentriol, HT-2 toxin and T-2 toxin), enniatins (A, A1, B, and B1), chlamydosporol and zearalenone were identified using GC/MS and/or NMR spectroscopy. Some of the crude extracts and fractions showed significant activity against brine shrimp at concentrations as low as 5 μg ml(-1), and are likely to be involved in the sheep feed refusal disorders. This is the first report of chlamydosporol production by confirmed Fusarium spp.; of the incidence of F. brachygibbosum and F. venenatum in Australia and of F. tricinctum in Western Australia; and of mycotoxin production by Fusarium species from Western Australia.

Fungi of the genus Fusarium are important plant pathogens and contaminants of cereal grains producing different types of mycotoxins. Enniatins are a group of mycotoxins with ionophoric properties frequently detected in North European grains. Within the Fusarium complex responsible for grain infection, Fusarium avenaceum, Fusarium poae and Fusarium tricinctum are the most potential enniatins producers. This study presents the development of two quantitative TaqMan MGB (Minor Groove Binder) assays for the specific quantification of F. avenaceum/F. tricinctum and F. poae esyn1 genotypes, respectively. Two sets of genotype-specific primers/probes were designed on the basis of esyn1 gene homologues encoding multifunctional enzyme enniatin synthetase. The specificity of the assays developed has been tested successfully on 111 Fusarium isolates from different geographical origins. The detection limits for F. avenaceum/F. tricinctum esyn1 genotype and F. poae genotype were 19 and 0.3 pg, respectively. The application of the assays developed on asymptomatic wheat grain samples revealed significant positive correlations between the enniatins levels and the amount of F. avenaceum/F. tricinctum esyn1 genotype (R=0.61) and F. poae esyn1 genotype (R=0.42).
