Fusarium species are causal agents of fungal diseases occurring frequently in numerous agriculturally important plants, including potato, garlic and are one of the common pathogens of tomato, causing root rot in the west part of Iran. Therefore, the objectives of this study were to isolate and identify disease-causing Fusarium species from infected tomatoes based on the morphological and molecu...

Fusarium wilt diseases caused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Biocontrol agents such asTrichoderma viride , Trichoderma harzianum and Pseudomonas fluorescens are applied to control Fusarium wilt of Arachis hypogaea. Experiments were conducted on the effect of culture filtrates of T.viride (1%), T.harzianum (1.5%), and P. fluorescens (2%) on biochemica...

Nine different Fusarium species were isolated from Acacia koa seeds, seedpods, seedling stem and root tissues, rhizosphere soil and soil surrounding roots of diseased trees. Fusarium oxysporum, the cause of koa dieback and wilt, was not isolated from seeds or seedpods but was found most commonly on roots and soil near diseased koa seedlings. Fusarium subglutinans was the most common species iso...

The genus Fusarium comprises a high number of fungal species that can be plant-pathogenic, causing diseases in several agriculturally important crops including cereals, and also can be harmful for humans and animals since many of them are toxigenic. The identification of mycotoxigenic Fusarium species still remains a most critical issue, given that the number of species recognized in the genus ...

The vascular wilt of tomato caused by Fusarium oxysporum f.sp. lycopersici is an important soil borne pathogen causes severe yield loss. The molecular characterization and their interaction with its host is necessary to develop a protection strategy. 20 isolates of F. oxysporum f.sp. lycopersici (FOL) were isolated from wilt infected tomato plants across Tamil Nadu. They were subjected to cultu...

Species determination by sequencing and PCR genetic chemotyping, used to determine the toxigenic potential of Fusarium strains, is fundamental for developing preventive strategies in food safety. Here we propose and statistically validate a quick protocol for standardizing the procedure of species determination by sequencing of the elongation factor 1and multiplex genetic chemotyping using the ...

Nine of 11 hematological patients with disseminated/deep-seated Fusarium infection tested at least twice for Aspergillus galactomannan (GM) had repeated positive results in the absence of Aspergillus isolation in culture. The centrifuged supernatants of 12 Fusarium isolates were tested by a GM enzyme-linked immunosorbent assay (EIA). All the isolates produced positive reactions when tested undi...

We aim to highlight the key factors for a good outcome of fungal keratitis. We describe a case of contact lens-related Fusarium keratitis in a young girl. After identification of Fusarium spp under direct microscopic examination and in culture, a prolonged treatment with topic natamycin 5% was started and administered for five months with restitutio ad integrum of the eye. Prompt microbiologica...

T-2 and HT-2 toxins are two of the most toxic members of type-A trichothecenes, produced by a number of Fusarium species. The occurrence of these mycotoxins was studied in barley samples during a survey carried out in the 2011-2014 growing seasons in climatically different regions in Italy. The percentage of samples found positive ranges from 22% to 53%, with values included between 26 and 787 ...

Fusarium head blight is one of the most important and most common diseases of winter wheat. In order to better understanding this disease and to assess the correlations between different factors, 30 cultivars of this cereal were evaluated in a two-year period. Fusarium head blight resistance was evaluated and the concentration of trichothecene mycotoxins was analysed. Grain samples originated f...
