Step by step
Solved in 3 steps
- A surgical technologist working in the Central Sterile Processing Department is asked to run the steam sterilizer (autoclave) with a biological monitor for the first load of the day without any instrument trays or items. What must be done with the bacterial sample after it is processed in the sterilizer?When you interpret a Gram-stained smear, you should also describe the morphology (shape) of the cells, and their arrangement. In the figure below, there are two distinct types of bacteria, distinguishable by Gram stain reaction, and also by their shape and arrangement. Below, describe these characteristics for both bacteria: Gram positive bacterium Gram negative bacterium Morphology cocci bacillus ArrangementMatch the expected result (purple, red, or colorless) to the following descriptions of Gram-stained cells.Consult your chart at the beginning of this lab report if you need help remembering the correct Gramreaction for each species. Choices may be used more than once. Staphylococcus aureus before the primary stain
- A patient enters the clinic demonstrating signs and symptoms of meningitis. A spinal tap is performed and the collected cerebrospinal fluid Gram stained. The results of the Gram stain reveal the infection is bacterial in nature. Based on the micrograph provided, which of the following best represents the interpretation of these results? The bacteria are Gram-positive cocci The bacteria are Gram-positive rods The bacteria are Gram-negative cocci The bacteria are Gram-negative rodsMatch the expected result (purple, red, or colorless) to the following descriptions of Gram-stained cells.Consult your chart at the beginning of this lab report if you need help remembering the correct Gramreaction for each species. Choices may be used more than once. Staphylococcus aureus after decolorizationComplete the following table with your observations from the prepared slide Name of the Bacteria Type of Endospore Staining Technique (+ or −) Drawing Clostridium botulinum Clostridium perfringens Bacillus anthracis
- 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?Based on the pictures provided, tell me what I have for the gram-positive, and what I have for the gram-negative? Possible Unknown Strains: Staphylococcus epidermidis, Bacillus subtilis, Staphylococcus aureus, Bacillus megaterium, Eschericia coli, Pseudomonas aeruginosa Name one negative and one positive of which I have.This is a Microbiology question about blood culture analyzers such as the BactecWhat is the process a technician takes if the analyzer alarms for a positive bottle?What action(s) are taken if there are no organisms seen in the Gram Stain made from that bottle?
- The below photograph shows a Gram-stained slide viewed using a light microscope set at brightfield of a clinical sample from a patient with symptoms suggesting an infection. The slide was viewed with x100 objective. What could be the most likely cause of infection? Gram positive bacteria, either rods or cocci Gram positive rod shaped bacteria or yeast Gram negative rod or cocci shaped bacteria Gram negative bacteria, either rods or cocciBased from the results obtained from Gram staining, explain why bacterial cells retained or changed their color. Briefly explain the principle behind the procedure. Cite advantages of differential staining method (Gram staining and endospore staining) over simple staining only. List other staining methods aside from those you performed in the laboratory. conclusion:Supposed you are to observe an unknown bacterial slide. In your initial observation, it appears to be in fading color and the shape of the specimen seems to be diffused. How are you going to troubleshoot the focusing of the specimen for you to identify clearly the bacteria?
