Introduction: One of the most important ways to describe bacteria is by their shape and arrangement. Morphology (Shell Shape)  Bacterial cells are much smaller than eukaryotic cells and come in…

Bacteria have contributed significantly to the rise in infectious diase. Bacteria as a class include a huge number of organisms, generally classified by biochemical characteristics (i.e., Gram stain characteristics) or morphological…

Scientists use classification systems to differentiate and identify species in medical microbiology. Bacterial species is a distinct organism that share an overall similar pattern of traits and also share about…
