Assessment of invasion frequencies of cultured HEp-2 cells by clinical isolates of Helicobacter pylori using an acridine orange assay.
1 Feb 1998
Abstract excerpt
AIMS: Recent studies suggest that Helicobacter pylori is an invasive enteropathogen. However, the efficiency with which this pathogen invades mammalian cells remains unknown. Therefore, this study was designed to investigate the invasion frequencies of HEp-2 cells by clinical strains of H pylori. METHODS: An acridine orange assay and cultured HEp-2 cell monolayers were used to determine the HEp-2 cell penetration...
