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 ...

Some protozoa infect the brain of their host, shaping its behavior in ways most suited to the pathogen, even if it leads to the suicide of the host THE ANCIENT DEBATE surrounding the existence of free ...

Protozoa are small, single-celled organisms that live in moist environments, such as ponds, swamps, and soils. They can survive themselves or sometimes live as a parasite inside the plants or animals.

The undisputed finality of life belies the inherent complexity behind the processes of cellular demise. Metazoan cell death functions in wide-ranging physiological processes and can occur by distinct, ...

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, ...

Researchers have analyzed drinking water and detected oocysts of Cryptosporidium and cysts of Giardia, two protozoa that cause outbreaks of diarrhea in humans. The levels detected are very low and do ...

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 ...
