Etymology: L, colonia
1 (in bacteriology) a mass of microorganisms in a culture that originates from a single cell. Some kinds of colonies, according to different configurations, are smooth colonies, rough colonies, and dwarf colonies.
2 (in cell biology) a mass of cells in a culture or in certain experimental tissues, such as a spleen colony.

colony

A local growth of large numbers of micro-organisms derived from one individual (a clone) or from a small number. A visible growth of bacteria or other microorganisms on a nutrient medium in a culture plate.

colony

  1. an aggregated group of separate organisms such as birds, which have come together for a specific purpose such as breeding.
  2. a group of incompletely separated individuals organised in associations, as in some hydrozoan COELENTRATES and polyzoans.
  3. a localized population of microorganisms, e.g. bacteria, derived from a single cell grown in culture.

colony

a discrete group of organisms, as a single cluster of bacteria in a culture that was produced from a single starting bacterium.

colony-forming units
colonies of pluripotent stem cells located and quantified in the spleen. Colonies grown in vitro interact with erythropoietin to give rise to morphologically identifiable erythroid cells.
colony-stimulating factors
cytokines produced by lymphocytes and mononuclear phagocytes which stimulate the growth and differentiation of hematopoietic cells. Includes granulocyte-macrophage colony-stimulating factor, monocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor.

In addition, this method cannot detect more than 1,000 colony-forming units (CFU) per tip.
Following enumeration of colony-forming units (cfu) per milliliter (2), each culture was adjusted to a concentration equivalent to 10% (v/v) BT product (~ 3 x [10.
Upon completion of the incubation, the colony-forming units (CFU) were counted with the aid of a stereoscopic microscope at a 10x to 15x magnification and a light source which was placed at a 45-degree angle to the plates.
If the bacterial count is too low to detect, it has to be repeatedly cultured and sub-cultured to verify the number of colony-forming units, by which time, even platelet units that might have initially been usable, become contaminated and expire.
One hundred twenty-seven Turkish children (median age, 12 months; range, 3-60 months) hospitalized with acute gastroenteritis of 12 to 72 hours' duration were randomly assigned to receive, in single-blind fashion, conventional therapy with or without 108 colony-forming units per day of Lactobacillus reuteri DSM 17938 for 5 days.
These results were confirmed by the study, which reported a significant decrease in the total number of colony-forming units (CFUs) of these pathogens in both direct and indirect line of sight.
pylori 51 was relatively more sensitive than the other two strains, which led to a 2-log reduction of colony-forming units.

On 109 of the 120 units, zero colony-forming units (CFUs) were found.
The effects were evident after 8 weeks of probiotic consumption, with the researchers noting that probiotics containing a daily bacteria volume of between 10 billion and 1 trillion colony-forming units (CFU) were most effective in addressing blood pressure.
A microbiological analysis also revealed that there was a smaller increase in the number of colony-forming units per gram in the coated cheese than in the uncoated samples.
Mean sputum colony-forming units (CFU) count declined more rapidly in the TMC207 than in the placebo group.
