OCCURRENCE OF FUSARIUM-SACCHARI VAR SUBGLUTINANS AND ITS MYCOTOXIN PRODUCTION ABILITY IN BROILER FEED

Spores of Fusarium sacchari var. subglutinans isolated from broiler fe ed BR1 were obtained at an average concentration of 1.5/mg in 25 % of tested samples. The spore concentration was increased from 1 to 100/mg of solid substrate (BR2; biscuit) or to 1/nL of Sabouraud broth after 3 weeks of cultivation. Mycotoxin analyses of these three substrates showed negative reactions for T-2 toxin and zearalenone but a positive reaction for deoxynivalenol (DON) which was found in concentrations o f 5 ppm in Sabouraud broth, 50 ppm in BR2 and 220 ppm in biscuit. Ther efore, our F. sacchari isolate appeared to be a DON producer.
