The bacteria in this image have been treated with gram straining procedure. Indicate the following information: A. Shape....... gram stain( +) , Gram (-) or both B. Stained color under microscope C. PG Wall thick, thin or both
- A microbiologist is working with a pure strain of bacteria isolated from a mixed sample. Which of the following would indicate that the bacterium is NOT Streptococcus mutans? Cells are arranged in chains. Secretes acids produced from metabolism of sucrose. Cells are cocci. Can grow in biofilms. Cells stain Gram negative.What cannot be determined using the details of Gram staining process? Question 7 options: bacterial shape cell wall structure antibiotic treatment motility structureA patient comes into a hospital and has what appears to be an infection. Your microscope is broken so staining is not an option. Design an experiment to determine if the infection is caused by gram positive or gram negative bacteria.
- Before viewing a specimen of pigmented bacteria on a slide under the light microscope, which of the following usually needs to happen (and why)? Staining (to increase magnification). Heat, radiation or antimicrobial chemical treatment (to kill the bacteria for safe observation). Add immersion oil (to increase resolution). Add a cover slip (to reduce contamination). The viewing chamber needs to be flushed of air (to create a vacuum).A microbiologist is working with a pure strain of bacteria isolated from a mixed sample. Which of the following would indicate that the bacterium is NOT Helicobacter pylori? Cells have flagella when viewed by flagellar staining. Secretes acids produced from metabolism of sucrose. Cells are curved rods. Produces and secretes urease enzyme. Cells stain Gram negative.Gram Stain Gram Reaction (Gram- positive or Gram- negative): Cellular morphology (shape & arrangement): _________________________________
