“…In Hungary, Sze´csi and Barto´k (1995) found both chemotype Ib and II isolates. In other studies, isolates belonging to chemotype Ia were found to be predominant in Japan, China, Argentina, Norway and Nepal, while chemotype Ib was predominant in the USA, Uruguay, New Zealand, Great Britain and Hungary (Lauren et al, 1992;Pineiro et al, 1996;Moon et al, 1999;Broggi and Molto, 2001;Carter et al, 2002). Consequently, there is no clear geographic structuring in the distribution of these chemotypes.…”

Genetic Variability of Central European Isolates of the Fusarium graminearum Species Complex

The main causative agents of Fusarium head blight in central Europe are Fusarium graminearum and F. culmorum. We examined the mycotoxin producing ability, aggressiveness and molecular variability of F. graminearum isolates. Altogether twenty-six Hungarian, three Austrian isolates and representatives of eight species identified in the F. graminearum species complex were involved in this study. Mycotoxin producing abilities of the isolates were tested by GC-MS and HPLC. The central European isolates were found to belong to chemotype I (producing deoxynivalenol). Most isolates produced more 15-acetyldeoxynivalenol than 3-acetyl-deoxynivalenol suggesting that they belong to chemotype Ib. All F. graminearum isolates were found to be highly pathogenic in in vitro aggressiveness tests. Phylogenetic analysis of random amplified polymorphic DNA profiles, and restriction profiles of the intergenic spacer region of the ribosomal RNA gene cluster of the isolates allowed clustering of the central European isolates into 17 and 16 haplotypes, respectively. When RAPD and IGS-RFLP data were combined,

“…The F. equiseti isolates included in our study produced scirpentriol and its acetylated derivatives. While they were two of the most toxigenic isolates, only one F. equiseti isolate from a New Zealand pasture has previously been shown to produce a trichothecene, namely sambucinol (Bosch et al 1989;Lauren et al 1988Lauren et al , 1992. The limited studies on sambucinol showed that it is less toxic than DON (Dowd et al 1989).…”

“…Toxic type A and type B microcyclic trichothecenes have been reported from Fusarium-contaminated pasture species in countries such as South Africa and New Zealand (Bosch et al 1989;Lamprecht et al 1986;Lauren et al 1992). Most of the Western Australian trichothecene-producing Fusarium species produced either DAS or DON, both well-known to cause feed refusal disorders and to be toxic to a number of different test animals (Vesonder et al 1973(Vesonder et al , 1976.…”

“…F. avenaceum, F. crookwellense, F. culmorum and F. sambucinum were prevalent in New Zealand pasture species (Bosch et al 1989;Lauren et al 1988Lauren et al , 1992; whereas F. acuminatum, F. avenaceum and F. oxysporum were predominant in South African annual medic pastures (Lamprecht et al 1986(Lamprecht et al , 1988(Lamprecht et al , 1990. The above studies highlighted the capability of at least some of these Fusarium species to produce a range of mycotoxins, including butenolide, moniliformin, trichothecenes, and wortmannin that can be lethal to rats, ducklings and/or sheep (Bosch et al 1989;Lamprecht et al 1986).…”

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.
