Nucleotide sequence and predicted translation product for an internal region of pneumococcal surface protein A (PspA). (A) database entry for a type 23F strain (GenBank/EMBL/DDBJ accession no. AF071811), (B) corresponding sequence for P833 used in nasal inoculations showing a frame-shift mutation within eight adenosines (shown by overlining) causing truncation of PspA as indicated, and (C) corresponding sequence from the last isolate obtained from subject FS1 which contains a compensatory two base pair deletion restoring expression of full-length PspA. Dash indicates a nucleotide deletion. The nucleotide and amino acid position is shown relative to the initiation codon.
