Effect of Freund's adjuvant on standard dark and pastel mink.

Following a long series of injections of homologous immunoglobulin in complete and incomplete Freund's adjuvant into mink, a moderate elevation in the level of gammaglobulin in the serum was observed in a few animals. Relatively mild pathological changes also were seen in liver, spleen, lymph nodes, lungs and kidney. It is concluded that the injection of Freund's adjuvant, under the experimental conditions described, produced lesions which were readily distinguishable from the lesions characteristic of aleutian disease of mink.
