Ribotyping analysis of three H. pylori-infected families revealed that intrafamilial infections occur among children and their parents in Japan. In one family, a boy and his parents were infected with a same H. pylori strain. In one other family, a boy and his father were infected with a same H. pylori strain, while the mother was infected with a distinct H. pylori strain. In the remaining family, a boy and his father, and his brother and his mother were respectively infected with two distintly-different H. pylori strains. In addition, after eradication therapy, the boy was reinfected with the mother’s (or brother’s) strain. In those three infected families, all the parents (100%) and 50% of the children were infected with H. pylori.}, pages = {147--151}, title = {小児の家庭内Helicobacter Pylori感染と分子疫学解析}, volume = {114}, year = {2000} }
