title: Freeze-fracture study of Bodo sp. (Kinetoplastida: Bodonidae).
abstract: Freeze-fracture technique was used to analyse the structure of conventionally fixed and quickly frozen Bodo sp., a free-living kinetoplastid. In the former method, chemically fixed and cryopreserved cells presented a corrugated membrane pattern in the flagella and cell body surfaces. In the latter, however, replicas from quickly frozen unfixed flagellates showed membranes with a smoother aspect, allowing the observation of intramembranous particles (IMPs) on the fracture faces, hardly detectable in previously fixed samples. The IMPs were randomly distributed throughout the cell surface, except in the sparsely seen short IMP rows.
