Pathogenic intestinal protozoa are responsible for clinically important infections in both the developed and the developing world. These organisms are responsible for both acute and chronic diarrhea, ...

Biologists have developed a sensor that employs one-celled protozoa to detect toxins in water sources. The new technique works by introducing protozoa into small chambers with water samples taken from ...

Three types of parasites can cause disease in humans. They are protozoa, carried by mosquitos, helminths, such as roundworm, and ectoparasites, for instance lice and bed bugs. Parasites are organisms ...
