All bacteria, both pathogenic and saprophytic, are unicellular organisms that reproduce by binary fission. Most bacteria are capable of independent metabolic existence and growth, but species of Chlamydia and Rickettsia are obligately intracellular organisms. Bacterial cells are extremely small and are most conveniently measured in microns (10-6 m). They range in size from large cells such as Bacillus anthracis (1.0 to 1.3 µm X 3 to 10 µm) to very small cells such as Pasteurella tularensis (0.2 X 0.2 to 0.7 µm) Mycoplasmas (atypical pneumonia group) are even smaller, measuring 0.1 to 0.2 µm in diameter. Bacteria therefore have a surface-to-volume ratio that is very high: about 100,000.

Humans constantly try to organize information about the world around them in meaningful ways. One way that we try to accomplish this is by classifying things into different groups based on how things are alike and different. Think about some of the things classified around your home or school and the methods used to classify non-living things.

In the famous Star Wars bar scene, an attempt was made to illustrate diverse organisms. It was a remarkably unimaginative effort: all of the life-forms illustrated had a striking resemblance to humans, all about the same size and with the same basic components (e.g., head, legs, arms). Without going outside this planet one can come up with a much more diverse set of organisms, as I hope this chapter demonstrates. Organisms vary from each other in multiple ways but in this chapter, I will focus on three aspects, two of which, size and form, are very straightforward, but the third aspect, composition, is less familiar. These characteristics have been shaped by evolution, and evidence of convergence (unrelated groups converging on a common form) and divergence (related groups showing a variety of forms) abound. Consequently, although form, size and composition are extremely important to an organism’s biology, they are remarkably poor indicators of phylogeny. This makes attempting to characterize the form of larger taxonomic entities (class, order, phylum) challenging, if not impossible. Composition, size, and shape are interrelated and significant to other aspects of an organism’s biology. Moreover, they are also often dynamic, changing during the existence of an organism.

Bacteria - Morphology, Biochemistry, 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. Cell shape, nature of multicell aggregates, motility, formation of spores, and reaction to the Gram stain are important. Those morphological features, including the shape and colour of bacterial colonies, are not always constant and can be influenced by environmental conditions. Important in the identification of a genus and species of bacteria are biochemical tests, including the determination of the kinds of nutrients a cell can
