    Study Notes

    Parasitology

    • Parasitology is the study of parasites, their hosts, and the relationship between them.

    Infestation and Infection

    • Infestation: the presence of ectoparasites, such as arthropods, that live on the outside of the host's body.
    • Infection: the presence of endoparasites, such as protozoa, helminths, and fungi, that live inside the host's body.

    Parasitism

    • Parasitism: a type of symbiotic relationship where one organism, the parasite, benefits, and the other, the host, is harmed.

    Hosts

    • Definitive hosts: the hosts in which the parasite reaches maturity and reproduces.
    • Intermediate hosts: the hosts in which the parasite undergoes development, but does not reach maturity.
    • Types of hosts: definitive, intermediate, paratenic, and accidental hosts.

    Parasite Classification

    • Obligate parasites: cannot survive without a host.
    • Facultative parasites: can survive with or without a host.
    • Permanent parasites: remain attached to the host for their entire life cycle.
    • Intermittent parasites: only attach to the host for part of their life cycle.

    Symbiotic Relationships

    • Commensalism: a type of symbiotic relationship where one organism benefits, and the other is not affected.
    • Mutualism: a type of symbiotic relationship where both organisms benefit.

    Ectoparasites and Endoparasites

    • Ectoparasites: parasites that live on the outside of the host's body, such as arthropods.
    • Endoparasites: parasites that live inside the host's body, such as protozoa, helminths, and fungi.

    Parasitology Subfields

    • Medical parasitology: studies parasites that affect human health.
    • Veterinary parasitology: studies parasites that affect animal health.
    • Wildlife parasitology: studies parasites that affect wild animals.

    Parasite Transmission and Life Cycle

    • Most common source of exposure to infection or infestation: contaminated food and water.
    • Portal of exit for parasites that cause phlegm: respiratory tract.
    • Mode of reproduction of most parasitic protozoa: binary fission.
    • Pathogenic stage in the general life cycle of parasites: trophozoite stage.
    • Sub-kingdom classification of multicellular parasites: Metazoa.
    • Mode of transmission of parasites: various, including direct contact, vectors, contaminated food and water, and vertical transmission.

    Diagnostic Techniques

    • Fecal concentration methods: used to detect parasites in stool samples.
    • Cellophane/scotch tape method: used to detect parasites in stool samples, especially for detecting pinworms.
