Bacterial Physiology

Medical Definition:	Physiological processes and activities of bacteria.
Guide Notes:	GEN or unspecified; prefer specifics; DF: BACT PHYSIOL
Previously Indexed:	Bacteria/physiology (1966-1997)

Bacterial Physiology Categories.

	Bacterial Adhesion - Physicochemical property of fimbriated (FIMBRIAE, BACTERIAL) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity.
	Bacterial Translocation - The passage of viable bacteria from the gastrointestinal tract to extra-intestinal sites, such as the mesenteric lymph node complex, liver, spleen, kidney, and blood. Factors that promote bacterial translocation include overgrowth with gram-negative enteric bacilli, impaired host immune defenses, and injury to the intestinal mucosa resulting in increased intestinal permeability. These mechanisms can act in concert to promote synergistically the systemic spread of indigenous translocating bacteria to cause lethal sepsis.
	Bacteriolysis - Rupture of bacterial cells due to mechanical force, chemical action, or the lytic growth of BACTERIOPHAGES.
	Luminescence, Bacterial - The emission of light by bacteria. It is applied to studies on bacterial viability, metabolism, genetics, adhesiveness, and other physiological properties.
	Nitrogen Fixation - Ability of certain bacteria, fungi, and blue-green algae to convert free atmospheric nitrogen to biologically usable forms (ammonia, nitrates, amino groups, etc.)
