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.
Schistosoma is a genus of trematodes, commonly known as blood flukes.They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria), with hundreds of millions infected worldwide.
Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, commonly known as tapeworms.
Ecological parasitology can be important to attempts at control, like during the campaign for eradicating the Guinea worm. Even though the parasite was eradicated in all but four countries, the worm began using frogs as an intermediary host before infecting dogs, making control more difficult than it would have been if the relationships had ...
Parasitology: the study of parasites; Immunology: the study of the immune system; Virology: the study of viruses; Nematology: the study of nematodes; Microbial cytology: the study of microscopic and submicroscopic details of microorganisms; Microbial physiology: the study of how the microbial cell functions biochemically.
Trematoda is a class of flatworms known as flukes or trematodes.They are obligate internal parasites with a complex life cycle requiring at least two hosts.The intermediate host, in which asexual reproduction occurs, is usually a snail.
Eggs of different species of parasitic worm. Parasitic worms, also known as helminths, [1] are a polyphyletic group of large macroparasites; adults can generally be seen with the naked eye.
Medical parasitology is concerned with three major groups of parasites: parasitic protozoa, helminths, and parasitic arthropods. [2] Parasitic diseases are thus considered those diseases that are caused by pathogens belonging taxonomically to either the animal kingdom , or the protozoan kingdom .
