Summary
Moniliformin contamination is prevalent in Norwegian grains, particularly wheat, though high levels are infrequent. This fungal metabolite is linked to Fusarium infection and growing seasons.
Area of Science:
- Agricultural Science
- Mycology
- Food Safety
Background:
- Moniliformin is a mycotoxin produced by Fusarium species.
- Fusarium species are common pathogens of cereal crops.
- Mycotoxin contamination in grains poses a risk to human and animal health.
Purpose of the Study:
- To investigate the prevalence and levels of moniliformin in Norwegian oats, barley, and wheat.
- To explore the association between moniliformin contamination and the presence of Fusarium species.
- To assess the impact of grain species and growing season on moniliformin contamination.
Main Methods:
- Analysis of 73 oats, 75 barley, and 83 wheat samples from 2000-02 growing seasons.
- Quantification of moniliformin using ion pairing reversed-phase high-performance liquid chromatography (HPLC) with diode array ultraviolet detection.
- Extraction and cleanup using acetonitrile/water and strong anion exchange columns.
Main Results:
- Moniliformin detected in 25% of barley, 32% of oats, and 76% of wheat samples.
- Maximum moniliformin concentrations were 380 (barley), 210 (oats), and 950 (wheat) µg kg⁻¹.
- Significant correlations found between moniliformin levels and grain species, growing season, and Fusarium infection (F. avenaceum/arthrosporioides, F. culmorum).
Conclusions:
- Norwegian grain exhibits high prevalence of moniliformin, especially wheat.
- Field conditions in Norway may not favor high-level moniliformin contamination.
- Further research is needed to understand the factors influencing moniliformin accumulation in grains.

01:28Fungal Phylum Microsporidia
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
