What is the main difference between gram-positive and gram-negative bacteria?
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...
Pre-Lab Questions: After staining what color will Gram positive bacteria be? What color will Gram negative bacteria be? What structure is more prominent in Gram positive bacteria than Gram negative bacteria? Why should I not spray water aggressively or directly on my bacteria on my slide?
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.)
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.

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...

What is one structural difference between Staphylococcus aureus (Gram-positive bacterium) and Escherichia coli (Gram-negative bacterium) that would make them have different susceptibilities to antimicrobial agents?
Create a list of gram-positive and gram-negative bacteria in human diseases. Each reply should contain at least 3 of each, and briefly describe disease symptoms. please include the references
