Molecular analyses of the phase-2 antigen complex 1,2,.. of Salmonella spp

The nucleotide sequences of the structural genes (fljB) for salmonellar flagellins representative of the phase-2 flagellar antigens 1,2.., 1,5.., 1,6.., and 1,7.. were determined. The results did not indicate linear epitopes for the antigen 1 subfactors, suggesting that conformational aspects are involved in determining these antigenic specificities.
