[Immunology of the mammary gland of cattle].

A successful control of udder diseases in dairy cattle widely depends on the knowledge of the mammary gland immune functions. They are responsible not only for the self-protection of this organ but also for the supply of the newborn with immunoprotective substances of humoral and cellular character. In the mammary gland, selected immunology methods may be used in the diagnosis of both local and systemic function disorders. Such evaluation represents a necessary prerequisite for a possible treatment by immunomodulators.
