1. how is gram stain done? 2. What types of bacteria are stained differently in the Gram stain? 3. What is the key step in the Gram stain that distinguishes between two different cell types? Explain why. The laboratory reported gram-negative bacteria arranged inside the leukocytes of the pus sample. Other tests confirmed the pathogen was Neisseria gonorrhoeae, indicating Tom had the sexually transmitted infection gonorrhea. 4. Describe the shape of the gram-negative bacteria shown in the photo. Dr. Nelson...

"The most widely used stain in microbiology is the Gram stain. Based on differences in the structure of the bacterial cell wall, the Gram stain divides bacteria into two major groups: Gram-positive and Gram-negative. Gram-positive cells have a thick layer of peptidoglycan, a polymer made of amino acids and sugars, in the cell wall. Crystal violet binds to peptidoglycan, rendering the cell purple. Gram-negative cells also have peptidoglycan and initially also stain purple. Since the peptidoglycan layer is much thinner,...
