Course objectives
At the end of the course, students will understand the problematics of cytology and morphology of bacterial cells and the techniques of microscopic and macroscopic assessments of bacterias. Students will be able to characterize cytological structure, their functions and stages in more or less complex life-cycles. Student will be also able to consider the formation of the bacterial biofilm and its importance and signal processes and interactions between bacterial cells. For a specific purpose, students will be able to consider the suitability and applicability of particular methods - microscopy, archiving of acquired material, processing and analysis of images. Abilities from that field will be useful not only in biological sciences, but will also help to understand the physiological processes of bacterial cells.
