[Maternofetal infection by parvovirus associated with antenatal meconium peritonitis].

A case of meconium peritonitis associated with materno-fetal infection by human B19 parvovirus is reported. The meconium peritonitis was recognized by ultrasonography at 25 weeks of pregnancy and was confirmed after delivery. Postnatal "opaque index" of the small bowel revealed multiple stenosis. Evolution was favorable and did not require surgery. Diagnosis of B19 parvovirus materno-foetal infection was documented on specific IgM antibodies and viral DNA in the maternal serum and specific IgM antibodies in the infant's serum. Thus, B19 parvovirus appears to be responsible for non lethal fetopathies.
