Bacteria Орындаған: Рустам Г.
Bacteria constitute a large domain of prokaryotic microorgan isms. Typically a few micrometres in length, bacteria have a number of shapes, rangingfrom spheres to rods and spirals.
Morphology Bacteria display a wide diversity of shapes and sizes, called morphologies. Bacterial cells are about one-tenth the size of eukaryotic cells and are typically 0. 5– 5. 0 micrometres in length Bacteria display many cell morphologies and arrangements
Bacteria often attach to surfaces and form dense aggregations called biofilms or bacterial mats. These films can range from a few micrometers in thickness to up to half a meter in depth, and may contain multiple species of bacteria, protists and archaea. The range of sizes shown by prokaryotes, relative to those of other organisms and biomolecules
Cellular structure Intracellular structures The bacterial cell is surrounded by a lipid membrane. This membrane encloses the contents of the cell and acts as a barrier to hold nutrients, proteins and other essential components of Structure and contents of a typical Gram the cytoplasm within the positive bacterial cell.
Overview of bacterial infections and main species involved
Bacteria were first observed by the Dutch microscopist Antonie van Leeuwenhoek in 1676, using a singlelens microscope of his own design Antonie van Leeuwenhoek, the first microbiologist and the first person to observe bacteria using a microscope.
