Abstract
A simple, effective procedure was developed for scanning electron microscopic examination of mycoplasmas and similar organisms. Cultivation of several mycoplasmal species, an acholeplasma, and a spiroplasma in broth media in Leighton tubes with cover slips resulted in attachment of the organisms to the cover slips. The attached cells were easily processed for either scanning electron microscopy or light microscopy. By eliminating the need for centrifugation, which was used in previously described techniques, physical stress on the cell is minimized. The effects of different preparative procedures on the morphology of Mycoplasma gallisepticum are described.
