Parasitology
Parasitology is the study of parasites, their hosts, and the relationship between
them. As a biological discipline, the scope of parasitology is not determined
by the organism or environment in question but by their way of life. This means
it forms a synthesis of other disciplines, and draws on techniques from fields
such as cell biology, bioinformatics, biochemistry, molecular biology,
immunology, genetics, evolution and ecology.

Parasitism
In evolutionary ecology, parasitism is a symbiotic relationship between
species, where one organism, the parasite, lives on or in another organism,
the host, causing it some harm, and is adapted structurally to this way of
life.

The following are several of the broad areas in which parasitologists work:
Medical Parasitology. …
Agriculture, Aquaculture, and Veterinary Parasitology. …
Wildlife and Fisheries Parasitology. …
Ecological and Systematic Parasitology. …
Biochemistry and Molecular Biology of Parasites. …
Immunoparasitology. …
Parasitology Educators.

Medical parasitology
Medical parasitology is the subject that deals with the parasites that infect
humans, the diseases caused by them, clinical picture and the response
generated by humans against them. It is also concerned with the various
methods of their diagnosis, treatment and finally their prevention & control.
A parasite is an organism that live on or within another organism called the
host.

These include organisms such as Plasmodium spp., the protozoan parasite which causes malaria. The four
species infective to humans are P. falciparum, P. malariae, P. vivax and P.
ovale.
Leishmania, unicellular organisms which cause leishmaniasis
Entamoeba and Giardia, which cause intestinal infections (dysentery and
diarrhoea)
Multicellular organisms and intestinal worms (helminths) such as Schistosoma
spp., Wuchereria bancrofti, Necator americanus (hookworm) and Taenia spp.
(tapeworm)
Ectoparasites such as ticks, scabies and lice
Medical parasitology can involve drug development, epidemiological studies
and study of zoonoses.

Class Sarcodina
Sarcodine, any protozoan of the superclass (sometimes class or subphylum)
Sarcodina. These organisms have streaming cytoplasm and use temporary
cytoplasmic extensions called pseudopodia in locomotion (called
amoeboid movement) and feeding.
Sarcodina (phylum Protozoa, subphylum Sarcomastigophora) A superclass
of protozoa which form pseudopodia for feeding and locomotion. There
are three classes, and many orders. The majority of species live in marine
aquatic environments but some occur in fresh water (and are important
members of the soil fauna) and some are parasitic in the intestinal tracts of
vertebrates and invertebrates. The superclass includes the Radiolaria,
known from the Cambrian, and the Heliozoa, which are exclusively
freshwater and have a fossil record that extends back only to the
Pleistocene.
