It would be gram negative bacteria because gram negative bacteria have outer membrane which is absent in gram positive bacteria.
This outer membrane of cell wall is made of LPS and it acts as endotoxin. Endotoxin is one of the virulent factors for Pathogenicity.
It also protects cell from antibiotics, detergent and enzymes like lysozyme.
66a. If you were to design a pathogenic bacteria justify why your bacteria would be Gram-positive...
Gram-positive and gram-negative bacteria differ in that A. Gram-positive bacteria have more peptidoglycan in their cell walls. B. Gram-positive bacteria have fimbriae but gram-negative bacteria do not. C. Gram-positive bacteria are spiral-shaped, and gram-negative bacteria are either rod-shaped or spherical. D. Only gram-negative bacteria can form endospores. E. There is no difference between gram negative and gram positive bacteria F. Gram positive are positively charged and gram negative are negatively charges An unknown bacterial species was found in the blood...
An antiseptic such as 70% alcohol dissolves lipids. It was observed that Gram-positive bacteria were more resistant to alcohol than Gram-negative bacteria. Is this an expected result? Why or why not, explain in detail.
MacConkey agar questions 4. Would this bacteria be a Gram positive or a Gram negative? How do you know? 5. Does this bacteria ferment lactose? How do you know?
Describe the color of Gram positive and Gram negative bacteria in each step of the Gram staining procedure. (Be sure to account for the procedure, the reagent, and the colors of Gram negative and Gram positive bacteria in your description.)
There may be more Which of the bacteria (A-E) would you expect to be catalase positive and why? than one of the bacteria positive for catalase. A OBLIGATE AEROBE B FACULTATIVE ANAEROBE CAEROTOLERANT ANAEROBE D OBLIGATE ANAEROBEE MICROAEROPHILE Extra: In a Gram stain one step could be omitted and still allow differentiation between Gram positive and Gram negative bacteria. What is that step? Why?
Name one media that will only allow Gram positive bacteria, but not Gram negative bacteria to grow and describe how this media select for gram positive bacteria.
43.Lipopolysaccharides (LPS) are found in: a. Gram-positive bacteria b. Gram-negative bacteria c. all Bacteria d. Archaea e. Eukaryotes ------------------------- 44. There are similarities and differences between Gram-negative and Gram-positive bacteria. Which of the following is not true? a. The cell wall of Gram-negative cells is composed of only one or two layers of peptidoglycan whereas the cell walls of Grampositive bacteria have many peptidoglycan layers b. Only Gram-positive bacterial cells have a periplasm 2/6/18 8 c. The cell membranes of...
