Giardia Lamblia

Written by: Solaris Diagnostics

Mature woman talks with her doctor about giardia lamblia in clinic.

Giardia lamblia is a flagellated unicellular eukaryotic microorganism that is a common cause of diarrhea in humans along with other mammals all over the world. This stool parasite is the main reason for waterborne outbreaks of diarrhea in the United States. It is also on occasion seen as a cause of foodborne diarrhea, according to the American Society for Microbiology. Giardia species have two major stages in the life cycle: (1) the trophozoite; and (2) the cyst. The trophozoite can exist freely in the human small intestine, whereas the cyst is passed into the environment. Infection of the host is initiated when the cyst is ingested with contaminated water or, less commonly, food. Infection is also possible through direct fecal-oral contact. The most common infection seen with exposure to Giardia lamblia is Giardiasis, found in the small intestine.

While some people can carry Giardia parasites without experiencing any symptoms, most people infected with this parasite will experience fatigue, nausea, diarrhea, vomiting, loss of appetite, bloating, abdominal pain, weight loss, headaches, and excessive gas. Giardiasis can be diagnosed through the testing of stool samples. Solaris Diagnostics tests stool using The Gastro Duplex Kit, which is a real-time polymerase chain reaction (PCR) array intended for the qualitative detection of nucleic acid from the viral, bacterial, and parasitic targets associated with gastrointestinal (GI) infections. The test consists of primer and probe sets to target each pathogen.
