When microbiologists are working with bacterial batch cultures, we would expect to see no net change in bacterial numbers in ________________ , as this is the stage where the cells of the inoculum are adjusting to their new environment (i.e., the fresh culture medium) and preparing for cell division.     stationary phase     death phase     lag phase     log/exponential phase

You are working for the CDC studying outbreaks of foodborne infectious disease. Your latest case is an incidence of food poisoning in a fast food restaurant. 5 people have been hospitalized for food poisoning, so you are working with that hospital to identify the source of the outbreak. Hospital clinicians have taken samples from each of the 5 patients for culturing. Each bacterial culture grew one likely microbe, each labelled P1, P2, P3, P4, and P5. All 5 isolates appear to have the same colony morphology on the plates, and all appear to be Gram-negative rods 1 micron wide and 3 microns long under the microscope. In addition, all 5 isolates appear to perform the same on an API 20E test strip that tests bacteria for 20 biochemical abilities. No other testing has been done yet. How would you best describe your set of isolates at this moment? O Each isolate is the same strain, of a different species O Each isolate is a different strain, of different species O Each isolate is a different…
