Domain Bacteria

∞ generated and posted on 2015.12.29 ∞

Taxon containing all cellular organisms whose chromosomes are not contained within a nuclear envelope (nucleus) and whose cell walls, if present, are peptidoglycan based.

Domain Bacteria are the bacteria as strictly defined, that is, to not include the members of domain Archaea as well.

These considerations are among additional distinctions. For example, all (or at least almost all) known prokaryotic pathogens are members of domain Bacteria. See more generally the concept of the Three-Domain System of organism classification.

Consider too simply bacteria. Contrast particularly with domain Archaea and also with domain Eukarya. The viruses of members of domain Bacteria are called bacteriophages, or phages for short.
