E coli testing

  1. 1. Coliquant EZ Gel What it is How to do it What it tells you
  2. 2. What it isPetri Dish culture testFor E coli and Coliform Bacteria
  3. 3. Indicator SpeciesFeces come from animalsFeces can’t be detected (spread out)Certain bacteria are found exclusively with feces= indicator bacteria
  4. 4. BacteriaHow do bacteria reproduce? Asexually Clusters of bacteria therefore form, known as colonies Colonies can be counted (bacteria too small alone)
  5. 5. Field SamplingA small bottle of water is filledExtra care is taken to: Keep the sample bottle clean Keep the sample bottle coldThe small bottle then gets poured onto petri dish back at lab
  6. 6. IncubationA measured amount of water sample is then poured onto a mediumThe medium feeds the bacteria.This is called “culturing” bacteriaWith food and warmth they multiply and form colonies
  7. 7. AnalysisColonies/100 mLColor of colony indicates if it’s a strain of coliform and e coli
  8. 8. Colors Pink= not E coli Deep purple= Teal= not E coli E coli
