  2. Colony-forming unit - Wikipedia

    en.wikipedia.org/wiki/Colony-forming_unit

    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 ...

  4. Log reduction - Wikipedia

    en.wikipedia.org/wiki/Log_reduction

    Log reduction is a measure of how thoroughly a decontamination process reduces the concentration of a contaminant.It is defined as the common logarithm of the ratio of the levels of contamination before and after the process, so an increment of 1 corresponds to a reduction in concentration by a factor of 10.

  5. Total viable count - Wikipedia

    en.wikipedia.org/wiki/Total_Viable_Count

    The count represents the number of colony forming units (cfu) per g (or per ml) of the sample. A TVC is achieved by plating serial tenfold dilutions of the sample until between 30 and 300 colonies can be counted on a single plate. The reported count is the number of colonies counted multiplied by the dilution used for the counted plate

  6. Mycobacteria growth indicator tube - Wikipedia

    en.wikipedia.org/wiki/Mycobacteria_growth...

    An instrument-positive tube contains approximately 10 5 to 10 6 colony-forming units per milliliter (CFU/mL). Culture tubes which remain negative for a minimum of 42 days (up to 56 days) and which show no visible signs of positivity are removed from the instrument as negatives and discarded. [ 1 ]

  7. Sterility assurance level - Wikipedia

    en.wikipedia.org/wiki/Sterility_assurance_level

    The difference in meaning between this and the probabilistic sense can be seen from an example: if careful assays before and after indicate that a procedure has inactivated 90% of the biological agents in some unit, then the procedure can be correctly reported to have achieved a 1-log reduction, even though the probability that the unit is ...

  8. Plate count agar - Wikipedia

    en.wikipedia.org/wiki/Plate_count_agar

    The colony-forming unit (CFU) is an appropriate description of the colony's origin. In plate counts, colonies are counted, but the count is usually recorded in CFU. Due to the fact that colonies growing on plates may begin as either a single cell or a cluster of cells, CFU allows for a correct description of the cell density.

  9. Acute myelomonocytic leukemia - Wikipedia

    en.wikipedia.org/wiki/Acute_myelomonocytic_leukemia

    Acute myelomonocytic leukemia (AMML) is a form of acute myeloid leukemia that involves a proliferation of CFU-GM myeloblasts and monoblasts.AMML occurs with a rapid increase amount in white blood cell count and is defined by more than 20% of myeloblast in the bone marrow.
