Acylamino-cephem-carboxylic acids of the formula I STR1 in which R1, R2 and R3 represent hydrogen or alkyl, R1 and R2 or R2 and R3 together may form an alkylene radical which may be substituted, X represents a single bond or NH, A represents a phenylene or thienylene radical which may be substituted, Y represents a single bond or oxygen and Z represents a 5- or 6-membered ring which may be substituted and which may be bound to an anellated ring system, and their physiologically tolerated salts and esters, a process for preparing these compounds and preparations containing them.
