Zearalenol was extracted from Fusarium-infected stems of corn from southern Italy. The toxin, which appeared as a single compound in various thin-layer chromatography systems, was resolved by high-pressure liquid chromatography into two components. A gas chromatography-mass spectrometry examination of a purified fraction confirmed the natural occurrence of zearalenol as a diastereomeric mixture...

We investigated the interaction between amphotericin B and azithromycin in vitro against 26 clinical isolates of Fusarium. Synergy was demonstrated in all isolates. Amphotericin B MICs were reduced from a mean of 1 mg/L when tested alone to a mean of 0.37 mg/L when tested in combination with azithromycin. Azithromycin demonstrated no activity against Fusarium when tested alone (MIC > 128 mg/L)....

In South Africa, the main causal organisms of Fusarium head blight (FHB) are Gibberella zeae (=Fusarium graminearum), F. culmorum and F. crookwellense. Fusarium graminearum and F. culmorum are associated with warmer regions, and F. crookwellense with cooler regions. Sporadic FHB outbreaks occur principally in the irrigation areas of the country. In favourable years significant damage is caused....

Fusarium is a type of mould capable of producing several diseases in cereals. Infection is a worldwide problem associated with yield losses and the accumulation of toxic secondary metabolites, mycotoxins, which are harmful to both humans and animals. F. graminearum, F. culmorum, F. avenaceum, F. poae, and F. tricinctum, including corresponding mycotoxins were quantified in wheat samples from 6 ...

Twenty-five isolates of Fusarium fujikuroi acquired from rice seeds and rice plants evidencing symptoms of Bakanae disease were evaluated to determine their mating types and characterize the formation of their sexual state. The mating types of the isolates were evaluated via multiplex PCR with the diagnostic primers of the mating-type (MAT) region: GFmat1a, GFmat1b, GFmat2c, and GFmat2d. Among ...

Rabbit antibody to cutinase-I, isolated from Fusarium solani f. pisi, was conjugated to ferritin. With this ferritin-conjugated antibody it was shown that germinating spores of this fungus excreted cutinase during the penetration of the host pisum sativum. This result constitutes the most specific and strongest evidence for an enzymic penetration of a plant cuticle by a pathogen during infection.

Eleven antifungal drugs were tested against representative isolates of the four phylogenetic clades of the Fusarium solani species complex obtained in a multilocus sequence analysis. They all showed very poor activity, with no differences among the clades. Amphotericin B was the most active drug.

Pathogenic effects of 6 Fusarium spp., viz., F. equiseti, F. longipes, F. scirpi (Section Gibbosum), F. oxysporum (Section Elegans), F. pallidoroseum (Section Arthrosporiella) and F. solani (Section Martiella) were studied on sunflower plants. Symptoms produced by Fusarium spp., were root-, collar-, stemand seedling rots, damping-off, stunting, wilting, tip burning and reduction in growth. Wilt...

VATCHEV, T. D., 2015. Fusarium root and stem rot of greenhouse cucumber: aerial distribution of inoculum. Bulg. J. Agric. Sci., 21: 650–654 Fusarium root and stem rot is one of the most damaging diseases of greenhouse cucumber. This study reveals development and spread of airborne inoculum of Fusarium oxysporum f. sp. radicis-cucumerinum the causal agent of the disease. Infective propagules of ...

Biodegradable capacities of fungal strains of Fusarium oxysporum (DSMZ 2018) and Fusarium culmorum (DSMZ 1094) were tested towards racemic mixture of chiral 2-hydroxy-2-(ethoxyphenylphosphinyl) acetic acid-a compound with two stereogenic centres. The effectiveness of decomposition was dependent on external factors such as temperature and time of the process. Optimal conditions of complete miner...
