Classification by morphology, biochemistry, and other features although genetic divergence highlights the evolutionary relationships of bacteria, morphological and biochemical features of bacteria remain important in the identification and classification of those organisms indeed, bacteria are classified on the basis of many characteristics.

Viruses are noncellular genetic elements that use a living cell for their replication and have an extracellular state viruses are ultramicroscopic particles containing nucleic acid surrounded by protein, and in some cases, other macromolecular components such as a membranelike envelope. 8 concepts structure and classiﬁcation of bacteria bacterial structural components the rigid bacterial cell wall maintains its shape and protects the cell from. Structure and classification of bacteria (medical microbiology and infection) bacterial classification is important , revealing the identity of an organism so that its behaviour and likely response to treatment can be predicted. Bacterial taxonomy is the taxonomy, ie the rank-based classification, of bacteria in the scientific classification established by carl linnaeus ,  each species has to be assigned to a genus ( binary nomenclature ), which in turn is a lower level of a hierarchy of ranks (family, suborder, order, subclass, class, division/phyla, kingdom and. Identification and classification of microbes agriculture, clinical microbiology, and food production) to perform this analysis, a bacterial culture is taken, and the fatty acids are.
Introduction, bacterial classification & immunology review different from parasites and fungi (eukaryotic) genotypic analysis bacterial structure and is a permeability barrier to large molecules. In bacteria, you may find the same structures in different forms for the first example, we will talk about the capsule the capsule is different depending on the type of bacteria. However, classification of bacteria based on their evolutionary relationships to one another, that is to say, drawing a sort of family tree of all bacterial species, is a relatively new development.

Cell wall composition varies widely amongst bacteria and is one of the most important factors in bacterial species analysis and differentiation for example, a relatively thick, meshlike structure that makes it possible to distinguish two basic types of bacteria. In bacteria, the cell wall forms a rigid structure of uniform thickness around the cell and is responsible for the characteristic shape of the cell (rod, coccus, or spiral) inside the cell wall (or rigid peptidoglycan layer) is the plasma (cytoplasmic) membrane this is usually closely apposed to the wall layer.
Classification of bacteria on the basis of nutrition: – on the basis of nutrition bacteria are classified as following: 1) autotropic bacteria: - these bacteria are nonpathogenic, free living, self sustaining in nature, which prepare their own food by utilisation of solar energy and inorganic components like carbon dioxide, nitrogen etc. Qualitative and quantitative analysis in microbiology various techniques have been devised to permit the analysis of the structure and function of microorganisms some techniques are qualitative in their intent that is, they provide a yes or no answer other techniques are quantitative in their intent these techniques provide numerical information about a sample. The field of bacteriology (later a subdiscipline of microbiology) was founded in the 19th century by ferdinand cohn, a botanist whose studies on algae and photosynthetic bacteria led him to describe several bacteria including bacillus and beggiatoacohn was also the first to formulate a scheme for the taxonomic classification of bacteria, and to discover endospores.
