  • b Cla, clarithromycin; Mz, metronidazole; S, sensitive; R, resistant; ND, not determined.

  • c Urease AB type according to the new classification of Owen (5).

  • d The AFLP type was arbitrarily designated when visual comparison indicated a high degree of overall similarity in the band patterns. Numbers indicate pattern variations.

  • e Ribotypes were previously determined for these strains (6). The two pretreatment strains were ribotype 1, and the two posttreatment strains were ribotype 4.
