Parasitic diseases (from the Greek. Parasitos - freeloader, a synonym for invasive disease) are a group of diseases caused by animal parasites (parasitic worms, protozoa, arthropods), and characterized by cyclical, often lasting post invazive development, usually very short, as well as immunity.
Among the parasitic diseases we can distinguish between helminthiases, protozoos, and enthomosis acariasis. Helminthiases are caused by parasitic worms. In total there are over 200 species of helminths. Among the most common helminth infections are ascariasis, schistosomiasis, enterobiasis. Protozoos is caused by protozoa. There are over 20 species of protozoa that cause disease amongst humans.
The most common are amebiasis, leishmaniasis, giardiasis, malaria, toxoplasmosis, trypanosomiasis. Enthomosis and acariasis are caused by parasitic arthropods, insects and mites. Enthomosis is miazy (diseases caused by parasitism of larvae of some species of flies) and dermatozoonos (dermatitis from insect bites), to Acariasis - scabies.
Parasites are well-known organisms that live off other organisms, using them as a habitat and a source of nutrients. In its turn, the body serves as a habitat and food source for the parasite.
