Giardia
 

  • What is it? Caused by a microscopic parasite called Giardia lamblia.
 
  • How is it transmitted? The most common way to become infected by Giardia is to drink contaminated water.
 
  • What does it affect? Once ingested, Giardia settles into your lower intestine resulting in fatigue, nausea, diarrhea or greasy stools, loss of appetite, vomiting, bloating and abdominal cramps, weight loss, excessive gas, headaches, abdominal pain.
 
  • What animals can potentially carry this? Many species including beaver. Beaver do not appear to be severely affected by the organism, but in some states parasites excreted by infected beaver appear to have contaminated water sources and caused outbreaks of the disease in humans. In fairness to beaver, a variety of mammals, birds, reptiles, amphibians and fishes are also known to harbor this organism, including humans.
 
* Due to the beaver's significant role in this parasite, Giardia is often referred to as "Bever Fever".
