n in detail gram stain biochemistry, procedures, gram-positive and gram negative cells.

izzes/00071/take/questions/600381 Regarding Gram staining, what will be the appearance of the Gram-positive bacteria if... All steps are done correctly? The slide is not heat-fixed prior to staining? Crystal violet was omitted? lodine was omitted? Only iodine was used? Acetone:alcohol was omitted? Too much acetone:alcohol was used or was left on for too long? I Not enough acetone:alcohol was used? Carbol fuschin or safranin was omitted?

Describe the staining of Acid fast negative organisms.

Out of the three gram-positive bacteria (Micrococcus luteus, Staphylococcus aureus, and Staphylococcus epidermidis).  Which of the following test(s) will help me identify the unknown gram-positive bacteria?     Gram Stain Wet Mount (motility testing) Endospore Staining Acid Fast Staining Differential & Selective Media (MacConkey, PEA, EMB, MSA Agar, Blood Agar, etc.) Oxidative-Fermentative Test Carbohydrate Fermentation MR-VP Testing Indole Production Citrate Utilization Triple Sugar Iron Testing Catalase Test

What is the purpose of fixing a smear? Mark all that apply: 1. To attach the bacteria to the slide  2. To cause the cells to shrink and become distorted 3. To kill the bacteria so they aren't harmed by the staining method 4. To break down the cell wall in order to make the cells accept stain 5. To kill the bacteria to make the slide safer to handle

Contrast the overall cell wall compositions of Gram positive and Gram negative bacteria, and go step-by-step in the procedure of the Gram stain. Describe what is occurring during each step within both Gram-positive cells and in Gram-negative cells. Be sure to include the appearance of each cell type at the end of each step.

microbial sensivity lab: in the procedure used to test bacterial growth against various temperatures (incubator, room, refrigerator, freezer), why should efforts be made to inoculate each tube with the same number of bacteria?

Describe the staining of Acid fast positive organisms.

You have a patient sample and have done a Gram Stain. When you look on the microscope, this is what you see. Which of the following tests would you use next? 中 МАС O HE • EMB O MSA

It is expected that amoxicillin would be more effective against Gram-positive bacteria.  Explain briefly why by making reference to the Gram stain?
