Questions: Question 3 1 pts ATSI report of A / H2 S indicates an organism that is positive for: Glucose fermentation Lactose/sucrose utilization H2 S production Both lactose/sucrose utilization and H2 S production Both glucose fermentation and H2 S production

The answer is the last one: Both glucose fermentation and \(\mathrm{H}_{2} \mathrm{~S}\) production.

Explanation for each option:

1. Glucose fermentation: An ATSI report of \(\mathrm{A} / \mathrm{H}_{2} \mathrm{~S}\) indicates that the organism is positive for glucose fermentation, as the "A" (acid) result typically indicates acid production from glucose fermentation.

2. Lactose/sucrose utilization: The ATSI report does not specifically indicate lactose or sucrose utilization unless specified separately. The \(\mathrm{A} / \mathrm{H}_{2} \mathrm{~S}\) result does not confirm this.

3. \(\mathrm{H}_{2} \mathrm{~S}\) production: The presence of \(\mathrm{H}_{2} \mathrm{~S}\) in the report indicates that the organism is positive for hydrogen sulfide production.

4. Both lactose/sucrose utilization and \(\mathrm{H}_{2} \mathrm{~S}\) production: As mentioned, the report does not confirm lactose or sucrose utilization, so this option is incorrect.

5. Both glucose fermentation and \(\mathrm{H}_{2} \mathrm{~S}\) production: This option is correct because the "A" indicates glucose fermentation, and the presence of \(\mathrm{H}_{2} \mathrm{~S}\) indicates hydrogen sulfide production.

In summary, the organism is positive for both glucose fermentation and \(\mathrm{H}_{2} \mathrm{~S}\) production.
