[A case report: horizontal infection of typhoid fever from daughter to mother (by suppository maneuver)].

A 22-year-old female was admitted to our hospital because of general fatigue and continuous high fever. Salmonella Typhi was detected from her blood. Her mother, 44-year-old female was admitted to our hospital a few days later because of high fever. She had nursed to her daughter and inserted suppositories to her daughter several times. S. Typhi was also detected from her blood. No other member of her family was infected with S. Typhi. From the study of the route of the infection, we are confident that S. Typhi was delivered from daughter to mother by insertion of suppositories.
