This bacterial infection is spread through food or water contaminated with human feces.

• A. E. coli
• B. Constipation
• C. Ascites
• D. Dysentery

Answer: (D)

Fecal-oral transmission of a bacterial intestinal infection that causes inflammatory diarrhea is being described. Dysentery fits this scenario best because it refers to an infection of the colon that often presents with diarrhea containing blood and mucus, typically caused by organisms like Shigella that are spread when food or water are contaminated with human feces. The key idea is that ingestion of contaminated food or water introduces bacteria into the gut, leading to inflammation and the characteristic bloody, mucus-filled stools.

Constipation and ascites are not infectious and don’t involve transmission via contaminated food or water, so they don’t match the scenario. While some E. coli infections can be acquired this way, the term dysentery specifically captures the fecal-oral spread of a bacterial infection with inflammatory, often bloody stool.
