Intracellular bacteria are bacteria that have the capability to enter and survive within the cells of the host organism. [1] These bacteria include many different pathogens that live in the cytoplasm and nuclei of the host cell's they inhabit. Two examples of intracellular pathogenic bacteria are Mycobacterium tuberculosis and also Toxoplasma ...
Other intracellular parasites have developed different ways to enter a host cell that do not require a specific component or action from within the host cell. An example is intracellular parasites using a method called gliding motility. This is the use of an actin-myosin motor that is connected to the intracellular parasites' cytoskeleton.
In comparison to eukaryotes, the intracellular features of the bacterial cell are extremely simple. Bacteria do not contain organelles in the same sense as eukaryotes. Instead, the chromosome and perhaps ribosomes are the only easily observable intracellular structures found in all bacteria. There do exist, however, specialized groups of ...
The two main fluid compartments are the intracellular and extracellular compartments. The intracellular compartment is the space within the organism's cells; it is separated from the extracellular compartment by cell membranes. [1] About two-thirds of the total body water of humans is held in the cells, mostly in the cytosol, and the remainder ...
Also called an antibacterial. A type of antimicrobial drug used in the treatment and prevention of bacterial infections. Archaea One of the three recognized domains of organisms, the other two being Bacteria and Eukaryota. artificial selection Also called selective breeding. The process by which humans use animal breeding and plant breeding to selectively control the development of particular ...
In order for pathogenic bacteria to invade a cell, communication with the host cell is required. The first step for invading bacteria is usually adhesion to host cells. Strong anchoring, a characteristic that determines virulence, prevents the bacteria from being washed away before infection occurs. Bacterial cells can bind to many host cell ...
Bacteria living in biofilms display a complex arrangement of cells and extracellular components, ... Some bacteria produce intracellular nutrient storage granules ...
Quorum sensing is used by both Gram-positive and Gram-negative bacteria because it aids cellular reproduction. Once in a biofilm, bacteria can communicate with other bacteria of the same species. Bacteria can also communicate with other species of bacteria. This communication is enabled through autoinducers used by the bacteria. [13]
