9. What organism is found in freshwater habitats and can infect a person if they C. diff Hepatitis Influenza

Based on the provided options and the context of freshwater-associated organisms that can infect humans, **Hepatitis** is the most appropriate choice. ### Explanation: 1. **Hepatitis**: - **Hepatitis A** is a viral infection that can be transmitted through contaminated water, including freshwater sources. It is often associated with poor sanitation and hygiene practices. 2. **Clostridioides difficile (C. diff)**: - This bacterium primarily causes infections in the gastrointestinal tract, especially after antibiotic use. It is not typically associated with freshwater environments. 3. **Influenza**: - The influenza virus is primarily transmitted through respiratory droplets and is not linked to freshwater habitats. ### Additional Information: While **Hepatitis A** is a waterborne virus, it's essential to ensure safe drinking water and proper sanitation to prevent its spread. If you are referring to other types of hepatitis (like Hepatitis B or C), these are generally transmitted through blood and bodily fluids, not through freshwater. If you were considering other freshwater-associated pathogens not listed in the options, organisms like **Leptospira** (causing leptospirosis) or **Naegleria fowleri** (causing primary amebic meningoencephalitis) are notable examples. However, based on the options provided, **Hepatitis** is the most relevant answer. **Answer:** Hepatitis is the organism among the options that is found in freshwater habitats and can infect a person.
