Bacteria and Archaea are classified by direct examination with the light microscope according to their morphology and arrangement. The basic morphologies are spheres and round-ended cylinders. But there may be others such as helically twisted cylinders, cylinders curved in one plane and unusual morphologies. Arrangements include pairs, tetrads, clusters, chains and palisades.

Recent work has established that bacterial morphology has an evolutionary history and has highlighted the survival value of different shapes for accessing nutrients, moving from one place to another, and escaping predators.

Thousands of Mycoplasmas are bacteria that are cell wall deficient and hence do not possess a stable morphology. They occur as round or oval bodies and as interlacing 7 Aug 2015 Not many virulence determinants of bacteria are phenotypically expressed. Among these, bacterial colony morphology plays a key role in the 2.3.1.6 General conclusions on the morphology of coryneform bacteria. 4. 2.3.2 V formation, transformation from rods into cocci, and difference in cell-wall Bacteria are difficult to see under the bright field microscope. Bacteria are almost colorless and therefore show little contrast with the medium in which they are adopted by bacteria to overcome environmental stressors. bacterial colony morphology features using two Pseudomonas aeruginosa strains.

Most of the bacteria have a rigid cell wall that provides a definite shape to the bacteria However, why bacteria should have a particular shape is a question that receives much less attention. The answer is that morphology is just another way microorganisms cope with their environment, another tool for gaining a competitive advantage.

INTRODUCTION • Bacteria is unicellular, free-living, microscopic microorganisms capable of performing all the essential functions of life. • They possess both deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). • Bacteria are prokaryotic microorganisms that do not contain chlorophyll. Hence, a colony of bacteria is a clone of genetically alike bacteria.
