Parasitolgy
What is parasitology? The study of a parasite, but what is a parasite? It is an organism feeding on live organic material such as another organism. This is a symbiosis (close permanent association) between the two organisms, in which one organism feeds on the other may cause damage to the host organism. Parasites have a wide range of sizes and structures. They include unicellular organisms that are a part of the lowest levels of our food chain. They may be a member of the fungus group and aid in decomposition. They may use flagella to take them from place to place such as Giardia migration through our intestinal tract and Trypanosoma movement through our blood stream. They may require a vector (transporter) to carry them to their potential host like Plasmodium that cause of malaria. They may be multicellular organisms such as helminthes (round worms or flat worms) that use larger animals or man to complete their life cycle.. 1. PARASITOLOGY - LIFE CYCLE AND WITH PICTURES ...
