2. I blood group
Definition:
A blood type classification based on a group of antigens which react with the antibodies anti-I and anti-i. The blood type occurs as a rare phenotype (called i) and in individuals with acquired (as opposed to inherited) hemolytic anemia.
3. i gene (lac I operon)
Definition:
A gene which is a part of the lac operon. It codes for a repressor protein, which prevents the transcription of genes that code for the enzymes that bring lactose into the bacterial cell and use it as a carbon source. The repressor protein prevents the unnecessary production of these enzymes when no lactose is present.

5. Ia antigen (class II histocompatibility antigen)
Definition:
A type of antigen which is responsible for any immune reaction, or rejection, of tissue grafts attached to the body which come from a genetically dissimilar donor.
6. iatrogenic
Definition:
Describes a negative reaction to medical treatment or therapy, usually as a result of an infection caused by the treatment. Also may refer to a disorder which arose due to the doctor's manner of exam or discussion of the patient.
7. ibuprofen
Definition:
A chemical which is used as an alternative to aspirin to treat headaches and other body pain. It has the chemical formula of C13H18O2 and at room temperature is a white powder. It is also used to treat inflammation symptoms of rheumatoid arthritis and osteoarthritis.
8. ice nucleation bacteria
Definition:
A type of bacteria which is able to act as a nucleation site around which ice crystals can form.
9. ichthy- (ichthyo-)
Definition:

15. icterus gravis (massive hepatic necrosis, malignant jaundice)
Definition:
A condition which includes jaundice (icterus), high fever, and delirium. Icterus gravis is either a rare complication of viral hepatitis and other liver diseases, a result of exposure to hepatotoxic substances, or a result of being insensitive to drugs.
16. icterus gravis neonatorum (extreme newborn jaundice)
Definition:
A condition of extreme jaundice (icterus) in a newborn which may result from a blockage in the bile duct in the liver, an immune reaction of the mother to the baby because of Rh factor (if the mother is negative and the baby is positive), erythroblastosis fetalis (a type of anemia which occurs in Rh+ babies of Rh- mothers), inflamed blood vessels, or complications due to the venereal disease syphilis involving liver cirrhosis.

20. ideal solution (Raoult's law)
Definition:
An ideal solution is any solution which obeys Raoult's law. Raoult's law gives the relationship between a solution's vapor pressure and a solvent's vapor pressure when the solute has no measurable vapor pressure (is nonvolatile). The law is stated as follows: "The partial pressure of a solvent over a solution, P1, is given by the vapor pressure of the pure solvent, P°1, times the mole fraction of the solvent in the solution, X1," or
P1 = X1·P°1
21. ideotype (idiotype)
Definition:
Any specimen which is not the holotype and which was not collected from the same location as the holotype, but which has been determined to be a member of the same taxon as the holotype by the original author of the holotype name.
