Giardiasis is a ubiquitous intestinal parasitic disease that affects up to 30% of the population in developing countries . It has also been reported to be the leading cause of outbreaks of waterborne disease in the USA . Infection is transmitted by the ingestion of cysts, which are parasitic stages that are resistant to chlorination and can remain viable for several weeks .

In some cases, especially in children, infection can lead to a wide range of symptoms, including abdominal discomfort and watery diarrhea; in severe cases, malnutrition, malabsorption and disruption of the weight curve may be observed.
Giardiasis is usually diagnosed in fecal specimens by light microscopy, which remains the...
