Parasites
parasite
(Science: biology) An organism which obtains food and shelter from another organism (for example giardia).
Games Parasites Play
Every organism has to cope with an assortment of predators and parasites.
Many biologists feel that one of the most potent forces of evolutionary adaptation is that created by the interactions between a host and its parasites.
Protozoan Parasites
Cryptosporidium parvum
The cysts of Cryptosporidium are of increasing importance because of their presence in water supplies.
parasites Organisms that live in, with, or on another organism. The parasites bene?t from the association without contributing to the host, usually they cause some harm to the host.
parasites: Plants or animals that live off another creature (or even inside it), obtaining food and protection without offering any benefit in return.
paternity: Identification of the father of a child.
Social parasites take advantage of interactions between members of social organisms such as ants or termites. In kleptoparasitism, parasites appropriate food gathered by the host.
Crop parasites (Dutch Elm Disease, Karnal Bunt, Corn Smut, etc.).
Mushrooms (Agaricus campestris, the commercial mushroom), molds, mildews, rusts and smuts (plant parasites), yeasts (Saccharomyces cerevisae, the brewer's yeast).
Plantae ...
Some parasites can pick up genetic material from one organism and carry it to the next. This has been observed in fruit flies in the wild.
Non-motile parasites that form spores
e.g. Plasmodium
The plant-like algae produce energy through photosynthesis. They include many single-celled creatures that are also considered protozoa, such as Euglena.
the study of parasites and their relationships. The University of Aberystwyth has a parasitology group.

endoparasite - parasites that live inside the host and feed internally on its tissues, e.g. tapeworm, liver fluke, lung-worm and many hymenopteran and dipteran parasitoids ...
suprapopulation of parasites All individuals of a single parasite species at all stages in the life cycle in all hosts in an ecosystem.
surf A wave that becomes so high and steep as it approaches the shoreline that it breaks.
Now some of the parasites, once they invade red blood cells they don't go on to develop and multiply inside the red cells to these next merozoite forms.
Viruses are obligate intracellular parasites and cannot replicate outside of a living cell. Every type of organism has viruses which parasitize them. Bacteria have viruses, we have viruses, fungi have viruses, plants have viruses....
Last, we'll talk about the parasites of the protist world. Not all protists go about their life eating little bits of food in a pond. Some, called sporozoans, are nasty little parasites.
Viruses are obligate intracellular parasites--meaning that they require host cells to reproduce. In the viral life cycle, a virus infects a cell, allowing the viral genetic information to direct the synthesis of new virus particles by the cell.
There is also a series of intracellular parasites that are "on the edge of life"[56] in terms of metabolic activity, meaning that many scientists do not actually classify these structures as alive, ...
The action of parasites, predators, or pathogens in maintaining another organism's population density at a lower average level than would occur in their absence.
viruses - obligate intracellular parasites that require the host cell's biochemical machinery to drive protein synthesis and metabolize sugars.
members of this phylum were formerly called sporozoans, and are parasites of animals, some of which cause dangerous human diseases.
Viruses are not plants, animals, or bacteria, but they are the quintessential parasites of the living kingdoms.
T Phages: A phage which infects Escherichia coli. Viral parasites of this type are labeled T1 through T7. T2 was the first phage observed under the electron microscope.
Thymine: A nitrogenous base. Pairs with adenine in DNA molecules.
an association of members of two or more species (not truly parasites) that live in, on, or with each other, and usually partake of the same food

5. How this phylum relates to the rest of the world - are there any parasites? Does it have economic significance? Medical uses?

These domains reflect whether cells have nuclei or not as well as differences in cell exteriors. There is also a series of intracellular "parasites" that are progressively less alive in terms of being metabolically active: ...
Immunoglobulin E (ige) An antibody that confers protection against parasites; ige also initiates allergic reactions.
biotic field, whenever that biotic field is compatible with the viruses' genomic sequences, they would be able to replicate themselves taking advantage of the energy and the catalytic molecules from the biotic medium where they progress as parasites.
Additionally, such peptidases are essential for several pathogenic parasites and bacteria.
