Emergence of Clarithromycin‐Resistant <i>Helicobacter pylori</i> (CRHP) with a High Prevalence in Children Compared with Their Parents

Abstract

The rate of clarithromycin resistance in H. pylori strains from Japanese children was extremely high, in contrast to those from their parents or adult patients. Prior history of clarithromycin usage in a child suggested development of clarithromycin resistance in resident H. pylori, which was originated from a parent.
