5. You use the Gram stain to try to differentiate bacteria in a sample. You find that all of the cells are Gram negative, but the teaching assistant insists there are both Gram positive and Gram negative cells present in the sample you are given. You definitely smeared a loop of the sample onto the slide and your fingers are stained a little purple and also a little red from handling the sides of the slide. Give a reason why...
can methylene blue stain (simple stain) be used to determine if bacteria is anaerobic or aerobic? is there a another dye that may confirm this? thanks you.
Assume that you stain encapsulated Streptococcus by applying a simple stain, carbolfuchsin (red) and then counterstaining with a negative stain nigrosin (black). Through the microscope you will see The capsule is stained (list color). The cells are stained The background was stained List the approximate size range of the following: Viruses Prokaryote cells Eukaryote cells Give two reasons for heat fixing a bacterial smear on a slide before staining. What is the reason that simple stains will dye bacterial cells?
describe the results you would expect to obtain in a simple stain of a mixture a Gram negative and Gram positive bacteria. will you see any difference in the color between Gram negative and Gram positive bacteria? why or why not?
What bacteria is this? What's the process of finding it? Negative Stain Gram Stain <

5. Why are simple stains able to "stick” to bacteria? Explain the chemical properties of the stain and bacteria surface. 3-Preparation of Bacterial Smears and Simple Stains Introduction Microbial cultures are handled using aseptic technique. Aseptie technique is a set of procedures used to minimize contamination of materials by microorganisms from the environment, and to minimize the spread of cultures around the laboratory. In this experiment, you will be using an inoculating loop to transfer bacteria from a culture tube...
