[Lysozyme in calves].

Relatively high lysozyme concentrations, depending on age, were recorded from intestinal content, spleen, liver, kidney, lung, lymph nodes, and mucosa of calves. Yet, only minor quantities of lysozyme were found in blood serum or plasma and in granulocytes. Physicochemical characterisation, precipitation, using polyclonal antisera, and crosswise neutralisation of lysis reaction were likely to suggest occurrence of immunological relationship reactions as well as differences between organ lysozymes, on the one hand, and intestinal lysozymes, on the other.
