The change in the appearance of the zones of inhibition of the different antimicrobials if the medication concentrations in the strips were slightly decreased. Introduction: MIC is defined as the minimum inhibitory concentration. E-test is a process by which MIC can be determined for an antimicrobial agent. It is determined by reading the number where the growth of the microorganisms intersects the strips. A teardrop-shaped zone of inhibition is noted due to the gradient of concentration of the antimicrobials. A slight decrease in the concentration of antimicrobials will produce a narrower teardrop shaped zone of inhibition as compared to the one given in Figure 20.12. In Figure 20.12, the image of an E-test is given showing the MIC determination. It shows the multiple strips containing a gradient of concentrations of antimicrobials. The MIC is shown by reading the number where the growth intersects the strip.

Summary Introduction

To review:

The change in the appearance of the zones of inhibition of the different antimicrobials if the medication concentrations in the strips were slightly decreased.

Introduction:

MIC is defined as the minimum inhibitory concentration. E-test is a process by which MIC can be determined for an antimicrobial agent. It is determined by reading the number where the growth of the microorganisms intersects the strips. A teardrop-shaped zone of inhibition is noted due to the gradient of concentration of the antimicrobials. A slight decrease in the concentration of antimicrobials will produce a narrower teardrop shaped zone of inhibition as compared to the one given in Figure 20.12.

In Figure 20.12, the image of an E-test is given showing the MIC determination. It shows the multiple strips containing a gradient of concentrations of antimicrobials. The MIC is shown by reading the number where the growth intersects the strip.

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding? Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
