title: Pathomorphological changes caused by T-2 trichothecene fusariotoxin in geese.
abstract: T-2 trichothecene fusariotoxin was administered to 110 laying geese and 33 ganders in the active egg production period through a tube at 2-day intervals on a total of 10 occasions. After the treatment, the geese were subjected to detailed pathomorphological examination. In the ovaries of layers, a cessation of follicle maturation and follicle degeneration dependent on the toxin dose were observed, accompanied by ovulation and consequent peritonitis in the birds that died and in some of those killed by bleeding. Additional findings included involution of the oviduct, lymphocyte depletion, necrosis and amyloidosis in the spleen, catarrhal enteritis, signs of colloid stasis in the thyroid and large numbers of secretory granules in the cytoplasm of the adrenaline-producing cells of the adrenal gland. In the ganders, toxin administration did not reduce the intensity of spermatogenesis but in the spleen, intestine and endocrine glands it caused changes similar to those seen in the layers.
