Signs and symptoms range from nonexistent to mild diarrhea to severe amoebic dysentery. Check the full list of possible causes and conditions now! Gastrointestinal diseases caused by protozoa are generally associated with exposure to contaminated food and water, meaning that those without access to good sanitation are at greatest risk. Toxoplasmosis does not usually cause any symptoms and most people do not realise they've had it. Based on limited data, it appears to be seasonal in ways that differ regionally and that are poorly understood.[1].

While their presence could have been incidental, it is persuasive that just a pair of treatments using Metronidazole in the water at 500 mg [five hundred milligrams] per ten gallons of water resulted in complete recovery of the fish. Protozoa living in the blood or tissue can be transmitted through a third source such as a mosquito. Although symptoms of the disease vary, most people who have the parasite cannot tell they are infected.

Protozoan GI infections are generally transmitted through contaminated food or water, triggering diarrhea and vomiting that can lead to dehydration. Signs and symptoms begin within seven to ten days after ingestion. Like other microbes, protozoa are abundant in natural microbiota but can also be associated with significant illness. These protists reproduce by binary or multiple fission. Unlike other pathogens, samples with protozoa cannot be simply identified through a culture. Infections caused by protozoa can be spread through ingestion of cysts (the dormant life stage), sexual transmission, or through insect vectors. Although symptoms of the disease vary, most people who have the parasite cannot tell they are infected. This group includes the dangerous diseases: amebiasis, malaria, trypanosomiasis, leishmaniasis. Infants who are born to mothers who carry the infection can experience complications at birth.
