Correct the answer

### Case Study: Bacterial Gastrointestinal Disease

**Scenario:**
Two patients are admitted to the hospital with bacterial gastrointestinal disease:

- **Patient #1** consumed contaminated egg salad with a large number of bacteria two days prior to illness.
- **Patient #2** consumed contaminated spinach salad with a small number of bacteria two days prior to illness.

**Laboratory Results:**
- Patient #1 is infected with *Salmonella typhimurium* (a neutrophile).
- Patient #2 is infected with *E. coli* O157:H7 (a moderate acidophile).

Both bacterial species are true pathogens.

**Question:**
Which of the following directly explains why the two individuals become ill?

- Option 1: Difference in the ability to produce scarlet fever between the bacterial species 
- Option 2: Differences in the infectious dose between the bacterial species

This case highlights the importance of understanding the infectious dose and pathogenic characteristics of bacteria in clinical settings.

The image contains two statements, likely part of a multiple-choice question or survey. The first statement is selected, and it reads:

- "Differences in the portal of entry of each pathogen between the two individuals"

The second statement, which is not selected, reads:

- "Different in the presence of the capsule between the bacterial species"

There are no graphs or diagrams present in the image.
