abyssal zone
The deepest region of the ocean; a sunless high pressure cold anerobic habitat.
From Aspergillus flavus toxin, a mycotoxin that typically poisons moldy animal feed and can cause liver cancer in humans and animals.
Pertainig to the metabolic pathways that serve multiple functions in the breakdown, synthesis and conversion of metabolites.
In chemistry, a compund that closely resembles another in structure.
AUG(start codon)
The codon that signals the point at which translation of a messenger RNA molecule is to begin.
A sterile state such as a pure culture. An axenic animal is born and raised in a germ free environment.
A thymine analog used in the treatment of HIV infection. AZT inhibits the action of the reverse transcriptase enzyme.
Five member heterocyclic compounds typical of histadine, which are used in antifungal therapy.
Proteins produced by certain bacteria that are lethal against closely related bacteria and are narrow spectrum compared with antibiotics, these proteins are coded and transferred in plasmids.
A bacterium that preys on certain other bacteria. It bores a hole into a specific host and inserts itself between the protoplast and the cell wall. there it elongates before subdividing into several cells and devoring the host cell.
benthic zone
The sedimentary bottom region of a pond, lake or ocean.
An active polypeptide that is a potent vasodilator released from IgE coated mast cells during anaphylaxis.
A zoonosis transmitted to humans from infected animals or animal products, causes a fluctuating pattern of severe fever in humans as well as muscle pain, weakness headache, weight loss and profuse sweating. Also called undulent fever.

A plasma clotting enzyme secreted by Staph. aureus. It contributes to virulence and is involved in forming a fibrin wall that surrounds staphylococcal lesions.
coagulase negative staphylococci
Opportunistic species that are usually part of the normal flora of the skin and mucus membranes. They cause infection when host defenses are low and lack many virulence factors such as coagulase.
A complex organic molecule, several of which are derived from vitamins(nicotinamide, riboflavin). A coenzyme operates in conjunction with an enzyme. Coenzymes serve as transient carriers of specific atoms or functional groups during metabolic reactions.
A enzyme accessory. It can be organic such as coenzymes, or inorganic, such as Fe2+, Mn2+ or Zn2+ ions.
The infolded inner membrane of a mitochondrion that is the site of the respiratory chain and oxidative phosphorylation.
A chemical substance produced by WBCs and tissue cells that regulate development, inflammation and immunity.
DiGeorge syndrome
A birth defect usually caused by a missing or incomplete thymus gland that results in abnormally low or absent T cells and other developmental abnormalities.
DNA polymerase
Enzyme responsible for the replication of DNA. Several versions of the enzyme exist, each completing a unique portion of the replication process.
