Prokaryotes are classified into two categories namely Archea and Bacteria. The difference between two is peptidoglycan layer and N-formyl methionine. The study of domain bacteria is known as Bacteriology. Bacteria which is not visible to the naked eye is found everywhere in the environment. Bacteriology
includes bacteria classification, parasitology, epidemiology, infections caused by bacteria, exotoxins of gram-positive bacteria, endotoxins of gram-negative bacteria, genetics and ecology of bacteria. Over past decades Bacteriology research has advanced rapidly.
