The reason that is important is because it basically tells you how many bacteria are alive and have the ability to protect your body from illness and conditions which would otherwise occur. CFU is basically the number of bacteria which can do your body some good. ...
What is the formula used for counting cfu ml?
cfu/ml = (no. of colonies x dilution factor) / volume of culture plate For example, suppose the plate of the 10^4 dilution yielded a count of 123 colonies. Then, the number of bacteria in 1 ml of the original sample can be calculated as follows: Bacteria/ml = (123) x (10^4)/ (1) = 1.23 × 10^6 or 1,230,000. ...
What is cfu/ ml in a biology lab?

How many CFU/mL would be presumptive of an uti?
The significance of colony count varies depending on the patient population. 26 Young, sexually active women often experience symptoms of UTI with colony counts less than 100,000 CFU/mL. In this setting, the presence of pyuria and a colony count less than 100,000 CFU/mL are sufficient to diagnose a clinically significant UTI. ...
