CFU is colony forming unit....
nowa days...in preparing vaccines instead of using the term lethal dose...cfu is used....

CFU/ML is CFU per milli-litre.
CFU stands for "Colony Forming Unit".
It depends on three things:
1) How many bacteria colonies do you observe? Count them.
2) How much milk sample do you take to culture?
3) What is your dilution factor?

Say, if you have 100 colonies and you use 0.1ml and your
dilution factor is 10^-2

Your CFU/ml would be (100/0.1) x 10^2

Hi pardeep

as u have asked in the health sec, CFU realted to health signifies colony forming unit.
In microbiology, colony-forming unit (CFU) is a measure of viable bacterial or fungal numbers. Unlike in direct microscopic counts where all cells, dead and living, are counted, CFU measures viable cells. By convenience the results are given as , colony-forming units per milliliter.
This technique allows the user to know how many CFU are per mL in the sample. Therefore, it allows knowing which is the microbiological load and the magnitude of the infection in humans and animals, or the degree of contamination in samples of water, vegetables, soil or fruits and in industrial products and the equipment.
