Course objectives
The aim of this lecture is to give a basic knowledge of morphology of bacteria with definite stages which differ in appearance during their life-cycles, their colonies and cells; characterization of cytologial structures and structural aspects; simple and complex life-cycles; characterization of biofilm and its signal procesess; interactions between bacterial cells; functional and physiological properties and adaptations on the macromolecular levelstructural differences between prokaryotes and eukaryotes; Besides the description of bacterial cell and structures in their diversity, the methods of the study and demonstartion of morphology of bacteria and cell structures are the essential part of this course (microscopy, image processing and analysis, image-evaluation procedures; At the end of this course, students should be able to understand of bacterial cell cytology and morphology, life-cycles, which is important for better understanding of bacterial physiology.
