Antibodies from the class of the immunoglobulins G against the peptide-subunit pentapeptide L-Ala-D-Glu(L-Lys-D-Ala-D-Ala) of peptidoglycan in biological test material, and against bacterial cell walls containing these peptidoglycans, characterised by a) specific bonding on pentapeptides of the general formula R - A1 - D - Ala (I) in which R represents an amino acid moiety having 1 - 3, preferably 3, amino acids from the group comprising Gly, L-Ala, D-Glu, L-Lys and A1 represents one of the amino acids D-Ala, D-Ser, D-Val or D-Leu, or b) specific bonding on isolated bacterial cell walls containing pentapeptides of the general formula I or c) specific bonding on gram-positive bacteria containing pentapeptides of the general formula I, process for their preparation, methods for their quantitative determination, and their use. |
