Perinatal Campylobacter fetus ss jejuni enteritis.

A 2-day-old breast-fed male infant developed mucoid and blood diarrhoea, and Campylobacter fetus ss jejuni was isolated from the stools but not from the blood. The probable source of transmission was his mother in whom symptoms of Campylobacter jejuni-associated illness began one day earlier. Both showed IgM, IgG and IgA antibody responses to autologous and reciprocal strains of Campylobacter jejuni as studied by ELISA.
