RAPD patterns obtained with primer 1281 and 1283 in two representative cases.

<p>M, 1 kb molecular marker (New England Biolabs); lanes 1–10, single colonies isolated from respective patients and “P” denotes pooled DNA sample (a) Multiple <i>H. pylori</i> colonies and pooled culture isolated from PG207 showed different RAPD patterns with primers 1281. (b) The same <i>H. pylori</i> colonies (PG207) gave different RAPD patterns with primer 1283 also. (c) Showing difference in RAPD patterns among single colonies obtained with primer 1281 for PG158 though, (d) almost identical RAPD patterns were obtained for these colonies with primer 1283.
