Substances that reduce the growth or reproduction of bacteria.
Bacteria
One of the three domains of life (the others being Eukarya and
archaea), also called Eubacteria.
They are unicellular prokaryotic microorganisms which generally possess rigid cell walls,
multiply by cell division, and exhibit three principal forms: round or coccal,
rodlike or bacillary, and spiral or spirochetal. Bacteria can be classifed by
their response to
Oxygen: aerobic, anerobic, or facultatively anerobic;
by the mode by which they obtain their energy: chemotrophic (via chemical reaction)
or phototrophic (via light reaction); for chemotrophs by their source of chemical energy:
lithotrophic (from inorganic compounds) or organotrophic (from organic compounds);
and by where they get their
Carbon: heterotrophic (from organic sources) or autotrophic
(from Carbon Dioxide). They can also be classifed by whether or not they stain
(based on the structure of their cell walls) with
Gentian Violet
dye: gram-negative
or gram-positive.
A broad-spectrum semisynthetic antibiotic similar to ampicillin except that its resistance to gastric acid permits higher serum levels with oral administration.
