Bacteria are mostly unicellular prokaryotic organisms. Bacteria are cells which have their metabolism and reproduce by means of cell division. Bacteria have a number of shapes, including spheres which are called cocci (staphylococcus, streptococcus, pneumococcus, meningococcus, etc.) and rods (colon bacillus, Bordetella pertussis, dysentery bacillus, etc.).
