STUDIES ON THE FINE STRUCTURE OF CANDIDA ALBICANS, WITH SPECIAL REFERENCE TO INTRACYTOPLASMIC MEMBRANE SYSTEM

Fine Structure of the Reiter Treponeme as Revealed by Electron Microscopy Using Thin Sectioning and Negative Staining Techniques

“…Figure 10 appear to be the polyphosphate granules as observed in bacteria (12,18). Similar granules has been found in sections of B. duttonii (28) and. Leptospira canicola (14).…”

ULTRASTRUCTURE OF NOCARDIA ASTEROIDES AS REVEALED BY ELECTRON MICROSCOPY

“…Intracytoplasmic membrane systems of various configurations have been found in eubacteria and actinomycetes as reviewed by Brieger(7), Glauert(12) and Takagi and Kawata (31). In agreement with the observations on Mycobacterium (19,20,26) Streptomyces (8,13,29) and Actinomyces (11,16,30) the internal structure of N. asteroides was found to be characterized by the presence of a welldeveloped membrane system.…”

“…Cytoplasm. As illustrated in most of the micrographs of thin sections, the cytoplasm of N. asteroides is composed of a fine granular texture similar to that seen in bacteria and streptomycetes (7,8,12,31). These cytoplasmic granules whose average diameter is approximately 150 A, are closely packed together and appear to correspond to the ribosomes of bacterial cells.…”

“…2, 5, 15. It is a unit membrane as found in bacteria and streptomycetes (7,12,31) and consists of two dense layers about 30 A thick, separated by a less dense layer about 40 A thick. The two dense layers are not always clearly defined, however they remain visible at times in autolysing cells as illustrated in Fig.…”

An Ultrastructural Study of Bacterial Invasion and Tissue Breakdown in Human Experimental Root-surface Caries

“…This presumption was confirmed by parallel cultural studies in which Gram-positive pleomorphic rods, including Actinomyces species, were the dominant bacterial group (Nyvad and Kilian, 1990). The large micro-organisms with thick laminated cell walls and membranous structures of various configurations in the cytoplasm, which characterized the bacterial deposits in two of the subjects, were reminiscent of Candida albicans (Takagi and Nagata, 1962;Walter and Frank, 1985). However, final evidence for the identity of these micro-organisms has to be verified by immuno-electronmicroscopic studies.…”
