Assessment of invasion frequencies of cultured HEp-2 cells by clinical isolates of Helicobacter pylori using an acridine orange assay.

Abstract

These results may have important implications for treatment and prevention strategies for this gastric pathogen. Furthermore, the acridine orange assay may be useful for assessing, in vitro, the ability of conventional and newer antibiotics, alone or in combination, to kill intracellular H pylori organisms.
