title: Electron spectroscopic imaging of calcium in the hydrogenosomes of Tritrichomonas foetus.
abstract: Electron spectroscopic imaging (ESI) of very thin unstained sections of Tritrichomonas foetus fixed in an osmium tetroxide solution containing calcium and potassium ferrocyanide showed the presence of calcium in the form of electron-dense deposits located in the hydrogenosomes.
