Figure 5.
Intraclonal heterogeneity of the nucleotide sequences of the V genes from case 4 before and after the eradication of H. pylori. Case 4B: before eradication; case 4A: after eradication. Case 4B-1 through case 4A-6 represents individual cloned sequences that are compared with the closest gene, DP-54. Silent or replacement mutations are indicated below the sequences, in lower case or upper case letters, respectively. The sequences of the PCR primers (both FR2B and ELJH) have been excluded.
