Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - Giardia intestinalis (former names: Giardia lamblia or Giardia duodenalis) is a protozoan flagellate that is among the most common disease-causing parasites in both developed and developing countries. It is one of the most frequently identified agents of waterborne diarrhea. Cases are especially common in areas with inadequate water and sanitation facilities. Humans are the major reservoir of infection, although other mammals, such as dogs, cats, and beavers, may be colonized and excrete cysts. Massive epidemics have occurred after the contamination of reservoirs, lakes, and streams, especially when community water supplies are not adequately filtered.
