Giardia is caused by the protozoan parasite Giardia lamblia, also known as Giardia intestinalis or Giardia duodenalis. This flagellated organism infects the intestines and can lead to gastrointestinal symptoms such as diarrhea, abdominal cramps, and nausea. Infection typically occurs through contaminated water, food, or surfaces.
