Electron microscope observations on the interaction of Mycoplasma fermentans with Trichomonas vaginalis.
Cultures of Trichomonas vaginalis were found to be contaminated with Mycoplasma fermentans. By means of electron microscopy the interaction between the prokaryotic organisms and the trichomonads was examined. Cells of M. fermentans were observed in the medium; some of them were attached to the surface of the trichomonads and others were observed in membrane-bounded vacuoles of trichomonads. They were also present in the ground substance of the cytoplasm. The mycoplasmas divided by binary fission like other prokaryotes. The most obvious change occurring in the infected trichomonad cells was an increase in number of vacuoles containing mycoplasmas.
