ABSTRACT:
Regions of the PspA protein of the R.times.1 strain of Streptococcus pneumoniae have been identified as containing protection-eliciting epitopes which are cross-reactive with PspAs of other S. pneumoniae strains and which is cross-protective. One region comprises the 68-amino acid sequence extending from amino acid residues 192 to 260 of the R.times.1 PspA strain while another region comprises the C-terminal amino acid sequence extending from amino acid residues 293 to 588 of the R.times.1 PspA strain.
