The organisms in humans and some animals caused by parasitic diseases are the group of eukaryotes and are named for parasites because they make throughout their life cycle or part of living at the expense of hosting it, called the host. These are parasite that causes the itching of skin.

A parasite, in the course of its life, has several guests, one of which may be the definitive host and other intermediate hosts. Types of parasites that make itching of skin

Parasitic diseases

How many sources exist for the spread of parasites?

There are two sources of infection of parasites: sick people and animals, and intermediate host animals, which, with or without apparent disease, it is sometime in the parasite’s life cycle.

We describe thirty species of protozoan parasites of man, of which about twelve are the diseases that originate in the body parasites.

Among the diseases caused by protozoa are few common features, because with serious diseases such as sleeping sickness, facilitate others that go unnoticed, as are some giardia.

Parasitic protozoa are found in different locations, can stay in the blood (malaria) in the tissues (leishmaniasis), intestines (amebiasis) or urethra (trichomoniasis).

These parasites do not leave any kind of immunity, once healthy, the person who has suffered can return to catching them.

Parasitic fungi have no chlorophyll and can not perform photosynthesis, and to feed, must obtain organic substances of human or animal, vegetable or other materials that are in the process of decomposition.

When staying in man originate conditions similar to those caused by bacteria, are caused by fungi that live in the mouth or intestines, such as candidiasis or actinomycosis.

Parasitic worms sometimes do not cause disease in humans, it was found that there are a number of healthy carriers.

Some vermiasis are more common in temperate areas (taeniasis, ascariasis, threadworm, tapeworm) and other tropical climates (filariasis, schistosomiasis) but these, for easy dissemination may occur in temperate climates.

Patients who are affected are not always vermiasis parasitized by the animal in its adult form, but the parasite can be found in its larval form, as happens in echinococcosis.

The most common are vermiasis intestinal people that have lost a high amount of nutrients, which are extracted by the parasite and it causes erosions in the digestive tract can cause various infections.
