[Ulcero-necrotizing enterocolitis: the role of cytomegalovirus. Apropos of a case].

The authors report a case of Wilson-Mikity syndrome in a preterm newborn, that was followed on the 28th day of life by a necrotizing enterocolitis with colic stenosis. The finding of cytomegalic cells on the pathologic examination of the intestinal lesions, the presence of the virus on direct examination of a tissue sample, the elevated IgG levels and the presence of IgM demonstrated a cytomegalovirus infection. The authors discuss the role of this virus in the pathogenesis of the affection, either as directly responsible for the enterocolitis or as a secondary colonization of previous lesions.
