    Endoparasite: The parasite which lives within the host is called Endoparasite. Invasion by the parasite is called Infection. Most of the protozoan and helminthic parasites causing human diseases are endoparasites.
    Endoparasites can be further classified as:
    • Obligate parasite: This parasite is completely dependent on its host and cannot survive without it. Example: Hookworms.
    • Facultative parasite: This parasite may either live as free living form or as a parasite when the opportunity arises. Example: Naegleria fowleri.
    • Opportunistic parasite: This parasite is capable of producing disease in an immune deficient host (like AIDS and cancer patients). Example: Toxoplasma gondii.
    • Zoonotic Parasite: This parasite primarily infects animals and is transmittable to humans. Example: Fasciola species.
    • Accidental parasite: This parasite infect an unusual host are known as accidental parasites. Example: Echinococcus granulosus infects man accidentally.
    • Wandering or Aberrant parasites: Parasites which infect a host migrate to the site where it cannot live or develop further are called aberrant parasites. Example: Dog roundworm infecting humans.
    Types of Host
    Definite host: The host which harbour the adult parasites or in which parasites undergo sexual method of reproduction is referred to as a definite host. The definite host may be a human or any other living organism. Example: Mosquito acts as a definite host for Plasmodium spp. in Malaria.
    Intermediate host: The host in which the larval stages of the parasite live or in which asexual reproduction of parasite takes place is called the intermediate host. Example: Man acts as an intermediate host for Plasmodium spp. in Malaria.
    Definition:
    What is Parasitology?
    Generally speaking, parasitology is the branch of microbiology that is concerned with the study of parasites. In the process, it gives focus to various characteristics of the parasite (morphology, life-cycle, ecology, taxonomy, etc), the type of host they infect/affect and the relationship between the two.
    In parasitology, parasites have traditionally been restricted to three main groups that include protozoa, helminths, and arthropods. However, they are also described based on where they are located on the host: Ectoparasites (those that live on the host- skin, etc) and endoparasites (those that live inside the body of the host).
    As a sub-discipline that studies a wide variety of organisms and relationship with their hosts, parasitology also encompasses some elements of such fields as entomology, helminthology, and epidemiology among others.
    Examples of parasites include:
    T. gondii
    P. carinii
    P. falciparum
    Leishmania
    Acanthamoeba
    Trichomonas
    Parasitology Classification
    Parasites of medical significance are divided into two main categories that include single-celled parasites (protozoa) and multicellular metazoa (helminths and arthropods).
    Protozoa parasites include malaria parasites (Plasmodium species) ciliates (e.g. B. coli) and flagellates (e.g. Leishmania), and amoeba (e.g. E. histolytica) among others. These are single-celled organisms that generally live inside the body of the host.
    For
    In the body, classification of protozoa parasites are based on the mode of movement:
    Mastigophora - Use flagella for movement
    Mastigophora - Use flagella for movement
    Sporozoa - Are non-motile in the body
    Sarcodina - Use amoeboid movement
    Ciliophora - Use cilia for movement
    As they host to another.
    During unfavorable conditions, they are also able to transform from the active trophozoite stage to inactive cysts that survive unfavorable conditions.
