Analytical electron microscopy of Bacterionema matruchotii calcification.
The morphology and elemental analyses of calcification occurring in Bacterionema matruchotii were studied by analytical electron microscopy. Early electron densities were found associated with metachromatic granules and cell membranes. Amorphous calcium phosphate appeared before apatite was detected.
