Species/Subspecies: Fusarium graminearum
Categories: Plant pathogen; toxic for animals; toxic for humans; of practical use
Etymology: Genus name: spindle.
Species epithet: of grass.
Alternative Species Name(s):Gibberella zeae, which is the name of the fungus in the teleomorphic stage.
Significance:This fungus is of great economic importance due to reduced crop yields and contamination of mycotoxins.
  [Very important]   
Macromorphology (smell):
Fusarium graminearum 
Fusarium graminearum
Forms banana-shaped septated macroconidia.
Spec. Char.:
Hosts/substrateDisease/effectClinical picture or result
Barley, maize, rice and wheat.Fusarium head blight (FHB) which is a devastating disease on wheat and barley.Infected grains become wrinkled and the remains will contain mycotoxins, which can poison livestock and humans.
MaizeStalk and ear rotDiscolouration and rotting of stem and ear
CattleDeoxydivalenol toxicosisFeed refusal, vomiting, poor growth and liver damage.
CattleZearalenone toxicosis.Reproductive defects (including abortion)
HumansSee cattleSee cattle
Virulence Factors: The mycotoxins deoxydivalenol (inhibits protein biosynthesis) and zearalenone (estrogenic mycotoxin). These mycotoxins can cause vomiting, liver damage and reproductive disorders in livestock, but are also dangerous to humans.
