Culture result growth of e. coli seen colony count >105 cfu / ml.

More information: More information is needed here. If this is a urine culture, it is probably not very significant. The textbook definition of a UTI would call for greater than 100,000 CFU. However, it is important to remember that not everyone reads the textbook and all diagnosis of Infection is clinical (e.g. based on history, physical exam, etc..).
