title: Membrane-associated viral complexes observed in stools and cell culture.
abstract: Viral complexes observed to be membrane associated rather than clumped by antibody were detected in a rotavirus-containing stool specimen by negative-stain electron microscopy. These "viral packets" were also observed in cell culture fluids after repeated passaging and contained up to 100 virions. Other stool specimens have been observed to contain similar packets of parvovirus-like particles. Such complexes must be expected in fecally contaminated water.
