title: The presence in faecal extracts of bacterial cell wall components resembling viral structures.
abstract: Electron microscopy of faecal extracts frequently shows organized structures which have a superficial resemblance to viral material in that it is more heterogenous and consists mainly of vesicles and tubules covered by subunits arranged in different patterns. Evidence is presented that this kind of material is derived from detached outer layers of bacterial cell walls.
