Abstract

Giardiasis is a protozoan flagellated zoonotic parasite, causing diarrheal disease caused by G.
duodenalis (or “Giardia” for short). Once a person or animal has been infected with Giardia, the
parasite lives in the intestines and is passed in stool (poop). It causes mild or severe diarrhea,
gas, stomach cramps, nausea (a feeling of stomach upset), or dehydration (body water loss causes
weakness of dizziness). Some people experience no symptoms at all. Cysts once pass are infective,
spreads easily and can spread from person to person or through contaminated water, food,
surfaces, or objects. Giardiasis shares some pathogens some or less the clinical manifestations.
