Culture and sensitivity test
Laboratory scientists culture a bacterium (one single bacteria) so the bacteria grows to a colony. Scientists create many specimens of colonies for each bacteria. Then they can expose each colony to a different antibiotic medication or new antibiotic to see how the bacteria react to it. They look for sensitivity--meaning, any reaction in the growth of the bacterial colony. The growth may have no change (no sensitivity), slow down, or stop. But even better, ingredients in antibiotics need to disrupt the way bacteria use nutrients, so scientists look to see if the bacteria die when exposed to that specific antibiotic.Different groups or families of antibiotics work best on certain bacteria. At the same time, certain bacteria favor conditions only in certain areas of the body. So the bacteria for a skin infection is different from the bacteria that infects the urinary tract, for example.
A close knit group of bacteria is known as a colony. All bacteria cells in a colony are genetically identical because they grew from a the same bacteria cell.
to know the amount of bacteria present
Not always. Sometimes, during protein synthesis, the DNA of bacteria makes a mistake and copies the wrong protein causing a defect. This can cause the bacteria in the same colony to be slightly different. Also, bacteria can evolve very quickly, so this can also cause the bacteria in one colony to be slightly different.
I think it is a colony.
a bacteria colony is the same as a colony that is found in bacteria and fungus begins to form once you've seen a colony.
The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar
A mass of bacteria is a colony.

The bacteria would generally be more similar
A colony is a group of identical bacteria (clones) which grow together into a visible cluster. Generally, a colony is grown on an nutrient agar plate (on a petri dish with bacteria food in it) such that it is large enough to see the bacteria. An additional type of colony is a "microcolony" which is a term used for a group of the same bacteria which grown in the dirt.
A group or cluster of bacteria derived from one common bacteria.

colony term is mainly used in biology... fungal colony, colony of bacteria etc.. basically a group name.
