[Submicroscopic organization of certain mycoplasma species]
Abstract:
The following Mycoplasma species have been studied by the method of ultrathin sections: A. laidlawii, M. hominis, M. arthritidis, M. gallesepticum. After fixation both in the presence and in the absence of sucrose and magnesium material of medium electron density, resembling a microcapsule, could be detected on the surface of all mycoplasmas under study. The cytoplasmic membranes of A. laidlawii, M. hominis and M. arthritidis had a symmetric or asymmetric profile, depending on the method of fixation, and the cytoplasmic membrane of M. gallescepticum had an asymmetric profile in all cases, which was seemingly a species specific characteristics. In the mycoplasmic cells fixed in the absence of sucrose and magnesium 3- or 5-layer annular membrane structures were detected in the cytoplasm.
