About Parasites Protozoa. Protozoa are microscopic, one-celled organisms that can be free-living or parasitic in nature. They are able to multiply in humans, which contributes to their survival and also permits serious infections to develop from just a single organism.rotozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly). Entamoeba histolytica is a protozoan.

These diseases are widespread in Africa, southern Asia, and Central and South America, especially among children.iagnosis. Parasitic diseases can be difficult to diagnose because many parasites do not show up on the routine blood tests that doctors perform. In addition, people with parasites are prone to get bacterial infections as well, which may fool doctors into thinking that the bacteria alone are the cause of the illness.

There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Alternatively, the immature (larval) states can cause disease through their infection of various body tissues. 2  Some consider the helminths to also include the segmented worms (annelids)—the only ones important medically are the leeches.
