The acute @entity137 of @entity2829 culture material of eight strains of Diplodia maydis in ducklings, as well as the ability of five of these strains to induce typical diplodiosis (a @entity4094 ) in @entity291 and @entity742 was shown. Typical diplodiosis was induced in 17 @entity742 and 11 @entity291 . Two of the five toxic strains were isolated from @entity2829 involved in diploidiosis outbreaks, the others from commercial @entity2829 . Strains inducing diplodiosis could be isolated from commercial @entity2829 from the USA, Argentina and South Africa. There was no correlation between the @entity137 of D. maydis strains in ducklings and their ability to induce diplodiosis in @entity291 and @entity742 . Some isolates were acutely toxic to ducklings and @entity35 but were unable to induce diplodiosis in either @entity291 or @entity742 . Others, equally toxic to ducklings and @entity35 , induced diplodiosis in @entity291 and @entity742 at low dose levels. Two doses, each of 5 g/kg, of @entity2829 culture material of isolates from the USA, Argentina and South Africa induced diplodiosis in @entity742 . Culture material incubated for less than 8 wk could not induce diplodiosis in @entity291 . Acute @entity137 in ducklings and @entity35 also increased with longer incubation periods. Cultures of non-sporulating and profusely sporulating strains were equally toxic to ducklings. Heat treatment of culture material for 48 days at 45 degrees C failed to reduce @entity137 in ducklings.
