Chapter 19.4, Problem 3CC
Summary Introduction
To determine: The bacterial growth after 16 hours whose multiplication time is 30 minutes.
Introduction:. The rate of multiplication of bacteria varies among the members of different species. For example, the multiplication rate for E.coli is 20 minutes while for Mycobacterium leprae it is 14 days.

The following image shows part of counting chamber you used to
estimate cell viability for yeast cells. If the dilution factor you used was
1:200, and the total sample volume was 5 ml, then calculate the cell
viability, the cell density and the total cell.
Q2) Why do cheek cells stain red with the gram stain? What is the big red circle in the middle of the cheek cell?
- Considering that it isn’t possible to identify bacteria from a Gram stain, why might a physician perform a Gram stain on a sample before prescribing an antibiotic?
- What cells stain red in a Gram stain? What cells stain purple in a Gram stain?
