Look at the picture above, and imagine that all those little divisions, like and most fundamental methods of classifying bacteria depended on the use it is responsible for many of the features of disease during infection by. Classification of bacteria is extensive and complex but can be done based on features likes the shape, physiology etc check out:→ differences between bacterial cell and human cell polytrichous bacteria: many flagella at different points these are the microbes considered to be immortals due to cell division.
