The hydrosoluble extract of mycobacteria is a tetrasaccharide-heptapeptide or its dimer, trimer or tetramer possibly associated with non-amino reducing sugars. The derivative has the formula: ##STR1## IN WHICH M IS A WHOLE NUMBER COMPRISED BETWEEN 1 AND 4 INCLUSIVE, N IS A WHOLE NUMBER AT LEAST EQUAL TO 1 AND R is an alkyl radical containing 9 to 17 carbon atoms.
