Abstract
|
|
|
It has been studied that fine structural changes of several microorganisms
(Escherichia coli, Neisseria gonorrhoeae, Staphylococcus aureus, Candida albicans,
Cryptococcus neoformans) treated with Polyvinylpyrrolidoneodine.
The alterations observed as follows:
1. It was observed that change of nucleoid, aggregation of ribosomal particles and other cytoplasmic alterations in E. coli, N. gonorrhoeae, S. aureus which were accompanied by marked breakdown of cell membrane and cell wall.
2. Particularly capsules of S. aureus was collapsed by polyvinylpyrrolidoneIodine.
3. Ultrastructural changes of above mentioned was also appeared that the more marked changes as the exposure time are longer.
4. The intra-cytoplasmic membrane systems in the cytoplasm which can observed in the control group of C. albicans and C. neoformans were disappeared because they were effected extensively by drug.
The electron transparent area of cells was increased in the longer exposure group and their cell membrane, cell wall and capsule were occurred marked changes.
5. In this experiment it was considered that treatment of polyvinylpyrrolidone
Iodine on several microorganisms occurred responsible cellular changes.
