In microbiology, a colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in ...

Formulated drugs are stored in container closure systems for extended periods of time. These include blisters, bottles, vials, ampules, syringes, and cartridges. The containers can be made from a variety of materials including glass, plastic, and metal. The drug may be stored as a solid, liquid, or gas.
The bioburden quantification is expressed in colony forming unit (CFU). There are generally established guidelines for the maximum CFU that a drug product can contain. [4] Contact plates or sterile swabs can also be used to test for microbes on a surface when compounding sterile products to ensure compliance with USP 797. [5]
The microbe, or the inoculating agent, must come from the same colony-forming unit, and must be at the correct concentration. This may be adjusted by incubation time and dilution. For verification, the positive control is plated in a hundred fold dilution to count colony forming units.
Contamination poses a frequent challenge depending on the method of collection used, thus a cutoff of 10 5 CFU/mL is used for a "clean-catch" mid stream sample, 10 4 CFU/mL is used for catheter-obtained specimens, and 10 2 CFU/mL is used for suprapubic aspirations (a sample drawn directly from the bladder with a needle).
