Patent ID: 7037510

Claim:
A polypeptide selected from the group consisting of (a) a fusion polypeptide which comprises a first amino acid sequence including at least one stretch of amino acids constituting a T-cell epitope from the M. tuberculosis protein ESAT-6 comprising at least 6 amino acids of SEQ ID NO: 1 and a second amino acid sequence including at least one stretch of amino acids constituting a T-cell epitope from the M. tuberculosis protein Ag85B comprising at least 6 amino acids of SEQ ID NO: 2 said first and second amino acid sequences optionally being fused via a linker sequence; (b) a polypeptide comprising an amino acid sequence analogue having at least 70% sequence identity to the sequence in (a) and at the same time being immunogenic; and (c) a fusion polypeptide which comprises a first amino acid sequence having at least 70% sequence identity to the first amino acid sequence in (a) and at the same time being immunogenic, and a second amino acid sequence having at least 70% sequence identity to the second amino acid sequence in (a) and at the same time being immunogenic, said first and second amino acid sequences optionally being fused via a linker sequence.
