Your lab partner is observing a Gram-stained slide of their unknown organism with 1000X total magnification.You look over and notice that he has not applied immersion oil to the slide. Explain what the role of immersion oil is in observing slides at 1000X total magnification. be as specific has possible
You are hired in one of the microbiology labs in Memphis and your first assignment to identify microbial samples from a local restaurant. You are given a set of slides and asked to classify the specimens as Gram positive or Gram negative. Based on this information answer questions 1-10:
6) What would be the last reagent you use to identify the bacteria?7) What type of visual aid you need to help you see the bacterial samples clearly?8) After the use of what reagent, you will be able to decide if you have a Gram positive or Gram negative bacteria?
The figure below is an electron micrograph of the gram-negative bacterium Azotobacter

- You begin with an overnight culture of approximately 108 organisms/ml and need a concentration of 103 bacteria/ml in order to get a countable spread plate. Describe how you would dilute your sample.arrow_forwardJoseph, being a know-it-all, told Mary that her method would not include all microbes. To demonstrate this, he took another 10g sample of Mary's garden and added starch. After the 1-week incubation time, he performed the same serial dilution scheme as Mary but used pour plating instead of spread plating. Shown below are the counts that he obtained after the incubation period. Compute for the CFU/g given the data below. Be sure to show complete solutions and box your final answer.

- Evaluation of Antiseptics and Disinfectants This experiment examines the bactericidal, or lethal, effect of commonly used antimicrobial agents. An antiseptic refers to a chemical agent used on tissue, while a disinfectant is used on nonliving surfaces or fomites (objects). The efficacy of various antiseptics and disinfectants are evaluated by the disk diffusion method, where inhibition of bacterial growth around a paper disk dipped in a chemical is used as an indicator of the effectiveness of that particular agent. When evaluating an antimicrobial agent, it is important to consider its mode of action as well as the type of microbe targeted. Antimicrobial chemicals damage cells in a variety of ways. Soaps and detergents are lipids, which dissolve lipids in the bacterial membrane. Agents such as chlorine and iodine destroy cellular proteins and spores. Alcohols dehydrate cells but are unable to penetrate spore coats. Phenol compounds such as Lysol® have properties of both soaps and…arrow_forwardA colleague performs a smear prep from a colony on an agar plate. Without staining it, he looks at it under oil immersion with a light microscope (1000x magnification). “Hm," he says, "it's not purple, so it must be gram negative." Briefly explain the error in his logic, and say what he would have to do to show whether the organism is gram negative or gram positive.
