A short description of bacteria

Bacteria The anatomy of a typical bacterium.

Medical Definition of Bacteria

In addition, strains of B. Who uses Descriptions of Fungi and Bacteria. However, other scientists quickly suggested that the bacteria that grew was simply modern bacteria that had infected the crystal sample.


These are powerful mediators of inflammation and septic shock that accompanies endotoxin toxemia. Since Lipid A is embedded in the outer membrane of bacterial cells, it probably only exerts its toxic effects when released from multiplying cells in a soluble form, or when the bacteria are lysed as a result of autolysis, complement and the membrane attack complex MACingestion and killing by phagocytes, or killing with certain types of antibiotics.

In monocytes and macrophages, three types of events are triggered during their interaction with LPS: The Rc, Rd2, and Rd1 mutants lack the phosphate group attached to Hep.

In contrast, Gram-negative bacteria have a relatively thin cell wall consisting of a few layers of peptidoglycan surrounded by a second lipid membrane containing lipopolysaccharides and lipoproteins. The term bacillus has been applied in a general sense to all cylindrical or rodlike bacteria.

It cannot grow and will eventually die. Two of the electrons are routed back to AMO, where they are used for the oxidation of ammonia quinol pool.

Reproduced by permission of The Gale Group. Asexual reproduction occurs by simple budding binary fission. A major problem facing the medical community today is the ability of disease-causing bacteria to develop a resistance to antibiotics and other antibacterial drugs.

Certain kinds of bacteria are also essential in the decay and decomposition of waste materials.

Nitrifying bacteria

Bacteria that need oxygen in order to live and grow. A type of bacterium with a rodlike shape. Finally, bacteria may or may not require oxygen to grow. A type of bacterium with a spherical round shape.


The primary structure of Lipid A has been elucidated and Lipid A has been chemically synthesized. Salmonella: Salmonella, (genus Salmonella), group of rod-shaped, gram-negative, facultatively anaerobic bacteria in the family Enterobacteriaceae.

Their principal habitat is the intestinal tract of humans and other animals. Some species exist in animals without causing disease symptoms; others can result in. a bacterial cell intermediate in morphology between a coccus and a bacillus; a very short bacillus spirilla, spirillum any flagellated aerobic bacteria having a.

Ecology. Nitrifying bacteria are a narrow taxonomic group in the environment, and are found in highest numbers where considerable amounts of ammonia are present (areas with extensive protein decomposition, and sewage treatment plants).

Nitrifying bacteria thrive in lakes and rivers streams with high inputs and outputs of sewage and wastewater and freshwater because of the high ammonia.

Description of Archaebacteria Also referred to as Archaea, the smaller set on non-nucleated cellular life that used to be referred to as bacteria or prokaroytes. Considered one of. Bacteria do not have sexes, but they do transmit DNA by several kinds of horizontal gene transfer.

This is how they share resistance to antibiotics from one strain to another. The complete DNA sequence is known for many bacterial strains.

Bacteria on your teeth are responsible for cavities and, of course, we have all heard of bacterial meningitis, bacterial pneumonia, and flesh-eating Staph infections.
