Guide Note

Giardia is an intestinal infection caused by a the single-celled parasite Giardia intestinalis, also known as Giardia lamblia. The parasite lives in its host's intestine and is spread through fecal contamination of food and water.¹

Fast Facts

Discovered in: 1681²
Discovered by: Anton van Leeuwenhoek²
Named after A. Giard and F. Lambl²
The parasite divides every 12 hours²
It can cross species¹
Known to infect dogs, cats, rodents and livestock¹

Symptoms

Symptoms usually develop a week or two after infection. Common symptoms include fatigue, abdominal cramping, bloating, diarrhea and weight loss. Infected individuals usually recover within two to six weeks although some cases can last for years.³

Life Cycle

The parasite is reproduces through cell division inside its host's intestinal tract. During its life cycle the parasite will drop from its hold on the intestinal wall and form a cyst. The cyst is passed in fecal matter and can survive three months in cold water. The cyst can't survive freezing temperatures. If the cyst is ingested, the new host's stomach acid will signal it to come out of hibernation and it will begin to reproduce starting the cycle again.²
