The purpose of this study was to identify the Fusarium species associated with selected medicinal plant species of Lamiaceae and Asteraceae in Kerman, the second-largest province of Iran. The plants showing wilting/rotting symptoms as well as asymptomatic plants were collected from main medicinal plants reservoirs and production areas. Fusarium species were identified based on...

Fumonisins are phytotoxic mycotoxins which are synthesized by various species of the fungal genus Fusarium such as Fusarium verticillioides (Sacc.) Nirenberg (ex F.moniliforme Sheldon) and Fusarium proliferatum. The trichothecene (TC) mycotoxins are secondary metabolites produce by species that belong to several fungal genera, especially Fusarium, Stachybotrys, Trichothecium, Trichoderma, Memno...

To the best of our knowledge, we present here the first report of a case involving granulomatous pododermatitis caused by Fusarium proliferatum in a 10-year-old female cat. A cutaneous mass developed on the foot-pad of the right hind leg. Nodular granulomatous dermatitis with numerous macrophages and multinucleated giant cells containing cytoplasmic fungal structures were revealed on histologic...

Partially purified lipoxygenase (LOX) extracts were obtained from Fusarium proliferatum, Fusarium oxysporum, Chlorella pyrenoidosa, and Saccharomyces cerevisiae; the enzymatic extract of F. proliferatum showed the highest LOX activity while those of F. oxysporum and S. cerevisiae demonstrated only 27.8 and 16.5% of the activity at pH 8.0, and 61.2 and 9.7% of the enzyme activity at pH 10.0, res...

Real-time PCR (qPCR) is the principal technique for the quantification of pathogen biomass in host tissue, yet no generic methods exist for the determination of the limit of quantification (LOQ) and the limit of detection (LOD) in qPCR. We suggest using the Youden index in the context of the receiver operating characteristic (ROC) curve analysis for this purpose. The LOQ was defined as the amou...

Fusarium head blight (FHB) is one of the most economically important and destructive fungal diseases of wheat (Triticum aestivum L.). Golestan province, one of the most important zones of wheat cultivation in Iran, is also known for its high rate of digestive tract cancer, which has been attributed to many biotic factors such as fungal toxins. In order to investigate the distribution of toxicog...

Mycotoxins pose a challenge to a safe food supply worldwide, and their threat is expected to worsen with our changing climate. The need for diligence is exemplified by the discovery of fumonisin B2 in wine, which joins ochratoxin A as a mycotoxin of concern in the grape-wine chain. To elucidate the mycotoxin risk in southeastern American wine, grape samples were collected from vineyards during ...

In a course of survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characteristics, 32 Fusarium species were i...

Infesting Fusarium species isolated from banana fruit samples were identified and quantified by morphological, mycotoxicological and molecular tools. A total of 19 Fusarium isolates were obtained: F. semitectum was most predominant (26%), followed by F. proliferatum (16%), F. circinatum (16%), F. chlamydosporum (10.5%), F. solani (10.5%), F. oxysporum (10.5%) and F. thapsinum (5%). Fumonisin B1...

Fusarium proliferatum and F. verticillioides are considered as minor pathogens of pea (Pisum sativum L.). Both species can survive in seed material without visible disease symptoms, but still contaminating it with fumonisins. Two populations of pea-derived F. proliferatum and F. verticillioides strains were subjected to FUM1 sequence divergence analysis, forming a distinct group when compared t...
