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 called Tom to explain the laboratory results and told him that he was required to report cases of gonorrhea to the Public Health Service. He indicated that Tom should expect a follow-up call so that his sexual partners, who may be infected with the pathogen but not yet showing symptoms, can be tested and treated if necessary. Dr. Nelson was confident that Tom would get the prompt and appropriate treatment he needed.

5. Name an antibiotic that could be effective for an uncomplicated case of gonorrhea.
