You are determining the purity of water sample by plating a small volume on a media that selectively allows the growth of coliforms.  A colony that would grow on this media would appear ——— color upon gram staining.

You want to make 50 mL of a 1:100 dilution of a bacterial sample.  How many milliliters of the bacterial sample should be transferred into water in order to achieve this dilution? (Remember, you want a final total volume of 50 mL).

Shigella is an enteric pathogen that is associated with severe, bloody diarrheal disease.  Which of the following tests will differentiate Shigella from E.coli as the causative agent of disease? You may use the chart below as a reference to decide your answer.

You are given a sample of bacteria at a concentration of 3 x 106 CFU/mL.  After mixing the sample , you transfer 1 mL into 99 mL of fresh media and label this Tube 1.  You mix the contents of Tube 1 and transfer 1 mL into 9 mL of fresh media and label this Tube 2.  Based on this dilution scheme, the estimated CFU/mL of  bacteria in Tube 2 should be:

An athlete approaches you with knee pain that she woke up with this morning. She has had pain in this knee before but says it’s bothering her more today because of the weather and she thinks she might have slept weird as well. She already took Tylenol for pain but tells you its not working and asks you if you have any more for her to take right now before she goes onto the field to play.
