|| Fusarium graminearum|
||Plant pathogen; toxic for animals; toxic for humans; of practical use|
||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.
||Forms banana-shaped septated macroconidia.
|Hosts/substrate||Disease/effect||Clinical 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.|
|Maize||Stalk and ear rot||Discolouration and rotting of stem and ear|
|Cattle||Deoxydivalenol toxicosis||Feed refusal, vomiting, poor growth and liver damage.|
|Cattle||Zearalenone toxicosis.||Reproductive defects (including abortion)|
|Humans||See cattle||See cattle|
||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.|
