Abstract
Summary.A total of 30 New Zealand white rabbits were divided into five equal groups. Animals in groups 1 and 3 were sensitized with bacillus Calmette‐Guerin (BCG), and those in groups 2 and 4 with inactivated cells ofMycobacterium bovis(Sensitinogen). Group 1 and 2 rabbits were fed 2 ppm day‐1aflatonin for 3 months. Group 5 served as control. Serum samples from animals in all groups were subjected to enzyme‐linked immunosorbent assays (ELISAs) to determine antibody titre and to protein electrophoresis to determine immunoglobulin levels. The antibody litres and the immunoglobulin levels were significantly decreased in the aflatoxin‐treated groups.Zussammenfassung.Dreißig weiße New Zealand‐Kaninchen wurden in fünf gleiche Gruppen geteilt. Die Tiere der Gruppen 1 und 3 wurden mit BCG‐Impfstoff, die der Gruppen 2 und 4 mit Hitze‐inaktivierten Zellen vonMycobacterium bovis‘Sensitinogen’ immunisiert. Die Tiere der Gruppen 1 und 2 wurden 3 Monate lang mit Aflatoxin in einer Dosis von 2 ppm/Tag gefüttert. Gruppe 5 diente als Kontrolle. Serumproben aller Gruppen wurden in ELISA‐Testen auf Antikörpertiter und in der Eiweisselektrophorese auf Gesamt‐immunglobulingehak untersucht. Sowohl die Antikörpertiter als auch die Immunglobulinwerte waren in den Aflatoxin‐behandelten Gruppen signifikant vermindert.Keywords
