Essay On Leg Wound

If a patient had speculated bacteria in a leg wound we could test it using agars and gram staining. If we used the agar testing method, a sample of the speculated bacteria could be streaked onto three of the different types of agars; nutrient agar, selective agar, and differential agar. Each agar would provide three different outcomes. The nutrient agar or also known as general purpose agar, what we would except to see is more bacteria as well as fungi as it has a mixture of nutrients that supports the growth of both bacteria and fungi, making this testing method a broader one (Talaro & Chess, 2105). The nutrient agar is really great for experiment because it provides the ideal conditions for the growth of bacteria and fungi, it can be thought of as a “kitchen sink”. As a result, for the purpose of the leg wound, we may see the growth of many different bacteria and fungi, …show more content…
If the suspected bacteria is one that is suitable for selective agar, then we can utilize this testing method, and by using this testing method, we would see the rate of growth for the bacteria, we can, in a sense, control the outcome (Talaro & Chess, 2105. The end result would be very limited to a specific type of bacteria as the growth of bacteria for this method, is very specific as to what bacteria is supported with this method. The differential agar supports the growth of many different types of bacteria, and is used to distinguish colonies of one bacteria form others, in other words in brings out the visible differences (Talaro & Chess, 2105. Some examples of visible differences would be the colony size, shape, and color and gas bubbles. The end result for this testing method, would be the growth of different types of bacteria, and being able to identify
