H. pylori viability by the live/dead assay method in the absence or presence of ampicillin at neutral and acidic pH. H. pylori incubated for 8 (A) and 16 (B) hours at pH 3.0 in the absence of ampicillin were less viable then at pH 4.5 and 7.4. Ampicillin significantly decreased the viability of the bacteria at both pH 4.5 and 7.4 but had no effect at pH 3.0 at both incubation times.
