Samples of grain from 40 New Zealand wheat and barley crops harvested in 2000 were assayed for Fusarium infection. Grain from all crops was infected, and Fusarium incidence ranged from 3 to 52% of grains infected, with a mean of 14%. Incidence of Fusarium was higher in spring wheat than in autumn wheat or spring barley. The highest level of infection (52% grains infected) was found in Otane whe...

In recent years, market pressures have reinforced the demand to solve the problem of an increased occurrence of Fusarium head blight (FHB) in cereal production, especially in wheat. The symptoms of this disease are clearly detectable by means of image analysis. This technique can therefore be used to map occurrence and extent of Fusarium infections. From this perspective, a separate harvest in ...

In immunocompromised patients, Fusarium species cause infections that lead to high mortality. Our case report describes a case of disseminated fusariosis in a neutropenic patient with AML after myelosuppressive chemotherapy, and a neutropenic multiple myeloma patient with Fusarium fungemia awaiting stem cell collection. Both cases highlight the fact that Fusarium can grow as yeast-like structur...

The biosyntheses of both macrocyclic trichothecenes in Myrothecium roridum and simple trichothecenes in Fusarium species begin with the cyclization of farnesyl pyrophosphate to form the sesquiterpene hydrocarbon trichodiene. A previous study showed that Myrothecium has a cluster of 3 genes that are homologous with Fusarium trichothecene genes: Tri4, a P450 oxygenase; Tri5, the sesquiterpene cyc...

The MICs and minimum fungicidal concentrations of amphotericin B, natamycin, miconazole, itraconazole, and flucytosine against 17 isolates of Fusarium solani, 14 isolates of Fusarium moniliforme, 10 isolates of Fusarium oxysporum, and 3 isolates of Fusarium semitectum were determined by a broth microdilution method. Amphotericin B and natamycin were the most active agents tested and failed to s...

BACKGROUND AND PURPOSE The Fusarium species are among the most important fungi in the medical, veterinary and agricultural fields. MATERIALS AND METHODS In the present study, 172 strains of these fungi have been analyzed. The high molecular weight DNAs were extracted from 23 reference strains as well as from 149 isolated Fusarium species. Using the designed nucleotide primers from rDNA of Fus...

Most species of Fusarium that produce fumonisin mycotoxins produce predominantly B fumonisins (FBs). However, Fusarium oxysporum strain O-1890 produces predominantly C fumonisins (FCs). In this study, the nucleotide sequence of the fumonisin biosynthetic gene (FUM) cluster in strain O-1890 was determined. The order and orientation of FUM genes were the same as in the previously described cluste...

As the 20th century ended, Fusarium mycotoxicology entered the age of genomics. With complete genomes of Fusarium graminearum and F. verticillioides and several Fusarium gene expression sequence databases on hand, researchers worldwide are working at a rapid pace to identify mycotoxin biosynthetic and regulatory genes. Seven classes of mycotoxin biosynthetic genes or gene clusters have been ide...

Fungal endophytes are found inside host plants but do not produce any noticeable disease symptoms in their host. In the present study, endophytic Fusarium species were isolated from roots of lawn grass (Axonopus compressus). A total of 51 isolates were recovered from 100 root segments. Two Fusarium species, F. oxysporum (53%) and F. solani (47%), were identified based on macroconidia and conidi...

The relationship between the toxicities of crude extracts and purified toxins of Fusarium spp. belonging to the section SporotrichieUla has been assessed. Toxicity was determined on the basis of death ofArtemia salina larvae and of viability and blastogenic response of bovine and human lymphocytes. Trichothecene-producing strains ofFusarium sporotrichioides and Fusarium poae were toxic toA. sal...
