You are working in a lab studying Streptococcus pyogenes as a cause of necrotizing fasciitiis. You have an overnight culture that you want to know the starting concentration of, so do a set of six 1:10 serial dilutions (putting 1 mL from the stock into a 9 mL blank), with tube #1 being 1:10, #2 is 1:100, etc. You plate 0.1 mL from tube 5 onto a blood agar plate and the next morning count 134 colonies. How many bacteria (measured in CFU/mL) were in the overnight culture flask? A. 1.34 x 10^4 CFU/mL B. 1.34 x 10^5 CFU/mL C. 1.34 x 10^6 CFU/mL D. 1.34 x 10^7 CFU/mL E. 1.34 x 10^8 CFU/mL F. cannot tell based on the data given - you'd need to know the volume of the original culture flask
