Abstract

Watersoluble extracts of corynebacteria cells are obtained by a process which comprises the steps of subjecting bacterial residues of corynebacteria containing diaminopimelic acid, e.g. Corynebacterium parvum cells, to a mild extraction and of isolating the watersoluble extracts so obtained by physico-chemical methods. Said extracts are useful as immunological adjuvants.
