Final answer:
Giardia lamblia and Escherichia coli are organisms that can induce dysentery, typically through contaminated food or water. Plasmodium falciparum is associated with malaria and Salmonella enterica with foodborne illness and typhoid fever, not dysentery.
Step-by-step explanation:
The organisms that may induce dysentery include certain protozoans and bacteria. Protozoans such as Giardia lamblia cause a type of gastroenteritis known as giardiasis. This is often transmitted through contaminated food or water and can result in severe diarrhea. The bacterium Escherichia coli, particularly pathogenic groups like Enterotoxigenic E. coli (ETEC), can also lead to gastrointestinal illnesses including dysentery.
Plasmodium falciparum, on the other hand, is associated with malaria and not dysentery. Salmonella enterica can cause foodborne illness and typhoid fever but is not typically associated with dysentery, which is specifically an inflammation of the intestine causing severe diarrhea with blood. Instead, bacteria like Shigella species are commonly associated with bacillary dysentery, also known as shigellosis.
