.In my results the slope of curves got from Microplate reader is seems less (less than 1) and negetive some times. What is the reason for that?

In my research I'm enumeraring the florescence intensity (FI) Vs E-coli concentration in river water. I measure FI by Tecan I control 200 pro and E-coli by Membrane filtration.
