Giardiasis is a diarrheal illness caused by Giardia lamblia. Once a person has been infected with Giardia, the parasite lives in the intestine and is passed in the stool. Giardia is found is soil, food, and water that have been contaminated with the feces of infected animals. Because the organism is protected by an outer shell, it can survive outside the body in the environment for long periods of time. Because it is spread worldwide, it has become one of the most important causes of chronic diarrhea. Despite the fact that it is a luminal pathogen, it evokes both systemic and local immune responses. Studies have found that about 86% of infected individuals develop serum antibodies against Giardia lamblia, most notably IgG and IgA.
