Gibberella and Fusarium Ear Rot and Fusarium Head Blight are major diseases affecting European cereals. These diseases are mainly caused by fungi of the Fusarium genus, primarily Fusarium graminearum and Fusarium verticillioides. These Fusarium species pose a serious threat to food safety because of their ability to produce a wide range of mycotoxins, including type B trichothecenes and fumonis...

Infections of Exophiala spp. and Fusarium spp. are often chronic and recalcitrant. Systemic disseminations, which mostly occur in immunocompromised patients, are often refractory to available antifungal therapies. The conserved target of rapamycin (TOR) orchestrates cell growth and proliferation in response to nutrients and growth factors, which are important for pathogenicity and virulence. IN...

This study was conducted to assess evolutionary relationships, species diversity and trichothecene toxin potential of five Fusarium graminearum complex (FGSC) isolates identified as genetically novel during prior Fusarium head blight (FHB) surveys in Nepal and Louisiana. Results of a multilocus genotyping (MLGT) assay for B-trichothecene species determination indicated these isolates might repr...

BACKGROUND Fusarium species are ubiquitous environmental fungi that occasionally provoke serious invasive infections in immunocompromised hosts. Among Fusarium species, Fusarium ramigenum, belonging to the Fusarium fujikuroi species complex, has thus far never been found to cause human infections. Here we describe the first case of invasive fusariosis caused by Fusarium ramigenum in a human and...

BACKGROUND Infections caused by Fusarium are difficult to treat because these fungi show in vitro and in vivo resistance to practically all the antifungal agents available, which explains the high mortality rates. An attempt to overcome fungal resistance is the combination of antifungal agents, especially those with different mechanisms of action. AIMS Evaluate the in vitro interactions of co...

Fusarium species are ubiquitous in nature, cause a range of plant diseases, and produce a variety of chemicals often referred to as secondary metabolites. Although some fungal secondary metabolites affect plant growth or protect plants from other fungi and bacteria, their presence in grain-based food and feed is more often associated with a variety of diseases in plants and in animals. Many of ...

Mycotoxin-producing Fusarium graminearum and related species cause Fusarium head blight on cultivated grasses, such as wheat and barley. However, these Fusarium species may have had a longer evolutionary history with North American grasses than with cultivated crops and may interact with the ancestral hosts in ways which are biochemically distinct. We assayed 25 species of asymptomatic native g...

The genus Fusarium is a species rich genus. Different media are required to study the morphological characters and classify different species, a time consuming technique. In this study pectic zymograms were used to identify species and form species of Fusarium isolates. Fusarium isolates (318) were obtained from different areas and hosts in Isfahan Province, Iran. Isolates were identified to sp...

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 ...
