Summary. In the mouse model, the mycotoxin ochratoxin A has a non‐selective suppressive effect on various immune and defence reactions. Apart from weight depression, lymphopenia, neutrophilia and eosinophilia, antibody‐producing cells, antibody titres in blood serum and phagocytosis of Escherichia coli by blood phagocytes become suppressed. Moreover, immunized animals show a lower survival rate after experimental infection with Pasteurella multocida as well as an increase in oxygen radicals in blood cells. Zusammenfassung. Das Mykotoxin Ochratoxin A wirkt nichtselektiv suppressiv auf verschiedene Immun‐ und Abwehrvorgänge bei Modellun‐tersuchungen an der Maus. Neben Gewichts‐depressionen, Lymphopenie, Neutrophilie und einer Eosinophilie kommt es zu Suppressionen Antikörper‐bildender Zellen, der Antikörpertiter im Blutserum, der Phagozytose von Escherichia coli durch Blutphagozyten, einer geringeren Überle‐bensrate immunisierter Tiere nach experimenteller Infektion mit Pasteurella multocida sowie zu einem Anstieg von Sauerstoffradikalen in Blutzellen.
