title: Small arrays of electron-dense cylinders in Escherichia coli cells.
abstract: Electron microscopy of unstained Escherichia coli cells from cultures kept near 0 degrees C after incubation at 37 degrees C revealed small areas of geometrically arranged electron-dense cylinders. Their morphology, organization, and occurrence are described.
