You go hiking with some friends in a nearby national park. The weather is cool when you set out but it quickly becomes very warm. Neither you nor your friends are carrying enough water. Eventually you find a stream and because you are so thirsty, you drink from it. About a week later you start to feel unwell. You have vomiting, abdominal cramps, and explosive diarrhea (loud, severe diarrhea). Your stool seems kind of oily and is difficult to flush away. You tell your RN brother about your signs and symptoms, and he tells you he thinks you may have giardiasis, caused by the protozoan Giardia lamblia.

Giardia lamblia is a protozoan and does not have a peptidoglycan cell wall like bacteria do. Instead, it has a plasma or cytoplasmic membrane composed of phospholipids. It also contains 80S ribosomes, and its DNA is contained within a membrane-bound nucleus. Giardia is an aquatic organism and is often found in contaminated water sources.
