Correlation between genotyping for cagA by PCR in isolated single colonies and by in situ hybridisation in biopsy sections from the stomach
| Patient | Disease | Site | PCR cagA* | In situ hybridisation | |
|---|---|---|---|---|---|

| *Results of PCR test for cagA to single colonies isolates; 7 to 10 colonies were isolated from each biopsy site. | |||||
| DU, duodenal ulcer; GU, gastric ulcer; ND, not determined; NUD, non-ulcer dyspepsia; PCR, polymerase chain reaction. | |||||
