 Waterborne disease constitutes bacteria, protozoa, metazoa, and viruses. So we're talking about protozoa. We have examples of protozoa. We have Gerdia and Christoporidium. That is what I am working mostly on with intermueba. So among the waterborne diseases caused by protozoa, Gerdia and Christoporidium constitute 95.5%. Then orders 4.5. So we see here that Christoporidium is the highest found in water than Gerdia. And then Christoporidium affects what are the symptoms of this disease? When you have it, one thing about this disease here in the developed world is anytime you have stomach ache or you have diarrhea, your thing is being caused by bacteria ecoli. But sometimes most of them are being caused by Christoporidium parasite, protozoan parasite, Christoporidium intermueba and Gerdia. So in Europe, a high increase of Christoporidium cases occurred from 2006 to 2009.
