CFU= colony-forming units. When you read a plate, you see circular cut-outs where the bacteria is growing. You presume that each circle is from a bacteria. If it is too blotchy, you probably need to do a serial dilution. If there is nothing there, you need to check a less-diluted sample.

CFU stands for colony-forming unit. CFU is a measure of viable bacterial numbers. Unlike in direct microscopic counts where all cells, dead and living, are counted, CFU measures viable cells.

Colony Forming Unit. This means the number of viable bacteria. However, depending on the bacteria, not all viable bacteria may form a single colony because the separation of bacteria, because the bacteria aggregate.

This is basically a single bacterium that is able to multiply and form colonies when plated.
