Beauvericin is a cyclohexadepsipeptide mycotoxin which has
insecticidal properties and which can induce apoptosis in mammalian cells. Beauvericin is produced by some entomo- and phytopathogenic Fusarium species (Fusarium proliferatum,
F. semitectum, and F. subglutinans) and occurs
naturally on corn and corn-based foods and feeds infected by
Fusarium spp. We tested 94 Fusarium isolates belonging to 25 taxa, 21 in 6 of the 12 sections of the
Fusarium genus and 4 that have been described recently, for
the ability to produce beauvericin. Beauvericin was produced by
the following species (with the number of toxigenic strains compared
with the number of tested strains given in parentheses): Fusarium
acuminatum var. acuminatum (1 of 4), Fusarium
acuminatum var. armeniacum (1 of 3), F. anthophilum (1 of 2), F. avenaceum (1 of 6), F. beomiforme (1 of 1), F. dlamini (2 of 2),
F. equiseti (2 of 3), F. longipes (1 of 2),
F. nygamai (2 of 2), F. oxysporum (4 of 7),
F. poae (4 of 4), F. sambucinum (12 of 14), and
F. subglutinans (3 of 3). These results indicate that
beauvericin is produced by many species in the genus
Fusarium and that it may be a contaminant of cereals other
than maize.
