One way bacteria can be classified is by the structure of the cell wall:

*'''[[:Category:Gram-positive bacteria|Gram-positive bacteria]]''': cell wall consists of peptidoglycan layer, with teichoic polymers attached, e.g. ''Staphylococcus''

*'''[[:Category:Gram positive bacteria|Gram-positive bacteria]]''': cell wall consists of peptidoglycan layer, with teichoic polymers attached, e.g. ''Staphylococcus''

*'''[[Category:Gram-negative bacteria|Gram-negative bacteria]]''':peptidoglycan layer is thinner, but surrounded by outer membrane of lipopolysaccharides and lipoproteins, e.g. salmonella

Another method of classification is the shape and arrangement of the bacteria themselves:

Another method of classification is the shape and arrangement of the bacteria themselves:

*'''[[:Caegory:Cocci|Cocci]]'''- round shape, e.g. Streptococci, Staphylococci, Neisseria

*'''[[:Category:Cocci|Cocci]]'''- round shape, e.g. Streptococci, Staphylococci, Neisseria

*'''[[Category:Rods|Rods]]''' or '''bacilli'''- long shape, e.g. Coliforms, Bacillus, Spirochaetes[[Category:Bacteria]]
