Web25 feb. 2024 · 2. It's not a linear growth rate; bacterial growth is an exponential function of time, whether you plot it on a linear or log scale (using a log scale does have some nice variance stabilising properties, though). And yes, the slope of the line above is the (exponential) growth rate. The intercept just tells you about the starting density. WebAcquisition of antibiotic resistance may be associated with a physiological cost for the bacterium. Determination of growth rate and generation time is often used to measure fitness costs associated with antibiotic resistance. However, fitness costs may be small and difficult to quantify and multiple models are required.
