You are testing water samples using the 3 tube protocol fordetection of coliform bacteria. You put the positive results in atable ^^^
1) You plate 100 ul of the original sample on Eosin MethyleneBlue and MacConkey's Agar. How many colonies would you expect tosee?
2) Which assay is more sensitive: viable plate counts or the MPN(most probable number) assay?
3) What is a limitation of the MPN assay?
