There are colony forming units that the cells follow during their formation.
Dosage may also be indicated as colony forming units (CFU).
The unit of measurement is cfu/ml (or colony forming units per millilitre) and relates to the original sample.
For urine collected via bladder catheterisation, the threshold is 100 colony forming units of a single species per millilitre.
A milk product containing Lactobacillus 5 billion colony forming units in 120 mL of milk twice a day has also been used.
The threshold is also 100 colony forming units of a single species per millilitre for women displaying UTI symptoms.
Several reports have shown that pulse-powered systems yield significantly lower counts of bacteria colony forming units compared to chemically controlled systems.
To be specific, the count actually represents the number of colony forming units (cfu) per g ( or per ml) of the sample.
In these conditions, copper alloy surfaces were found to kill several million Colony Forming Units of Escherichia coli within minutes.
The following equation is used to calculate the number of colony forming units (CFU) per ml from the original aliquot / sample:
The samples are then cultured and colony forming units (cfu) of Legionella are quantified as cfu/Liter.
Definition 1 3 Colonized catheter: Growth of 15 colony forming units (cfu) on semiquantitative culture from catheter tip in the absence of accompanying clinical symptoms.
The number of CFU (colony forming units) reduced significantly with increase in the concentration of AgNPs in paint loading 0.5ppm and higher.
During summer storm events (the worst case, especially if after a prolonged dry period) bacterial levels can exceed 10,000 cfu (colony forming units), so caution must be exercised regarding contact with the water.
The Miles and Misra Method (or surface viable count) is a technique used in Microbiology to determine the number of colony forming units in a bacterial suspension or homogenate.
In previous research on indoor bioaerosol in residential environments, microorganisms have been quantified by conventional culture-based techniques, in which colony forming units (CFU) on selective media are counted.
Intravaginal suppositories containing 100 million to 1 billion colony forming units of Lactobacillus acidophilus (Vivag, Pharma Vinci A/S, Denmark) given twice daily for 6 days has also been used.
Often, the unit used is CFU (colony forming units), which is proportionate to the number of organisms present multiplied times the number able to reproduce on a culture medium such as a Petri dish.
A portion of the combined mixture was plated onto TSA plates to determine the number of colony forming units (CFUs) of each strain in the initial inoculum (the -2 hour time point in figures).
In plantabiological control of crown gall by TFX-producing strains Agrobacterium vitis strains were suspended in sterile distilled water prior to the determination of colony forming units (CFU) per ml.
For lung infections in children: 120 mL of milk twice daily containing 5 billion colony forming units each of Lactobacillus acidophilus and Bifidobacterium contained in a specific product (HOWARU Protect, Danisco).
Bacteriuria can be confirmed if a single bacterial species is isolated in a concentration greater than 100,000 colony forming units per millilitre of urine in clean-catch midstream urine specimens (one for men, two consecutive specimens with the same bacterium for women).
In order to establish a microbial count the extraction media is filtered and the filters are then placed onto agar plates for an incubation of up to 15 days at 37 2 C. At the end of the incubation period the number of colony forming units are counted.
The optical density of the specimen was measured at 600 nm on a Stasar III spectrophotometer (Gilford Instruments, Oberlin, Ohio, USA) and quantified by interpolation on a previously constructed curve of optical density plotted against colony forming units (cfu).
