Anaplasmosis

|
AnaplasmosisA tick-borne disease of cattle, sheep, and related ruminants caused by a microorganism called Anaplasma marginale and characterized by anemia and jaundice. Also called gallsickness and gall sickness.
RELATED TERMS--------------------------------------
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Microorganism
An organism that can be seen only under a microscope. Categories of microorganisms include Algae, Bacteria, Fungi, Protozoa, Viruses, or Subviral Agents. Also referred to as microbe.
Anemia
Anemia is a condition in which a deficiency in the size or number of erythrocytes (red blood cells) or the amount of hemoglobin they contain limits the exchange of oxygen and carbon dioxide between the blood and the tissue cells. Most anemias are caused by a lack of nutrients required for normal erythrocyte synthesis, principally iron, vitamin B-12, and folic acid. Others result from a variety of conditions, such as hemorrhage, genetic abnormalities, chronic disease states or drug toxicity.
Jaundice
A condition in which the skin and the whites of the eyes become yellow, urine darkens, and the color of stool becomes lighter than normal. Jaundice occurs when the liver is not working properly or when a bile duct is blocked.
Gall
The bile produced in the liver and stored in the gallbladder.
SIMILAR TERMS--------------------------------------
Anaphase
The stage in mitosis or meiosis during which the sister chromatids (mitosis) or homologous chromosomes (meiosis) separate and migrate toward the opposite poles of the cell.
Anaphia
The inability to feel touch. From the Greek prefix an, not + Greek haphe, touch = inability to (feel) touch. A person with anaphia is said to be anaptic.
Anaphylactic shock
A severe and sometimes life-threatening immune system reaction to an antigen that a person has been previously exposed to. The reaction may include itchy skin, edema, collapsed blood vessels, fainting, and difficulty in breathing.
Anaphylactoid purpura
See: Sch”nlein-Henoch purpura.
Anaphylatoxin
Substance capable of releasing histamine from mast cells.
Anaphylaxis
Immediate hypersensitivity response to antigenic challenge, mediated by IgE and mast cells. It is a life-threatening allergic reaction, caused by the release of pharmacologically active agents.
Anaplasia
Characteristics of a cell (structure and orientation) that make it identifiable as a cancer cell. Malignant.
Anaplastology
The art and science of restoring a malformed or absent part of the human body through artificial means. An anaplastologist makes prosthetic devices. From the Greek ana, again, + plastos, formed. See also: Prosthesis.
Anaprox
See: Naproxen.
Anaprox ds
Anaprox ds is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): naproxen sodium.
Anaptic
Suffering from an impaired sense of touch, (a state called anaphia) or tactile anesthesia. An anaptic person has anaphia (an, not + Greek haphe, touch = inability to (feel) touch.
PREVIOUS AND NEXT TERMS--------------------------------------
Analysis, linkage
"Study aimed at establishing linkage between genes. Today linkage analysis serves as a way of gene-hunting and genetic testing. Linkage is the tendency for genes and other genetic markers to be inherited together because of their location near one another on the same chromosome. A gene is a functional physical unit of heredity that can be passed from parent to child. All genes in humans are pieces of DNA. Most genes contain information for making a specific protein. The term ""genetic marker"" is broader than a gene. A genetic marker is simply a segment of DNA with an identifiable physical location on a chromosome whose inheritance can be followed. A genetic marker can have a function and thus be a gene. Or a marker can be a section of DNA with no known function.Because DNA segments that lie near each other on a chromosome tend to be inherited together, markers are often used as tools for tracking the inheritance pattern of a gene that has not yet been identified but whose approximate location is known. The statistical estimate of whether two loci are likely to lie near each other on a chromosome and are therefore likely to be inherited together is called a LOD score. A LOD score of 3 or more is generally taken to indicate that the two loci are linked and are close to one another."
Analytic sensitivity
The lowest level of a substance that can be detected by an analytic method.
Analytic specificity
How well an assay detects only a specific substance and does not detect closely related substances.
Anaphia
The inability to feel touch. From the Greek prefix an, not + Greek haphe, touch = inability to (feel) touch. A person with anaphia is said to be anaptic.
Anaphylactoid purpura

Anaptic
Suffering from an impaired sense of touch, (a state called anaphia) or tactile anesthesia. An anaptic person has anaphia (an, not + Greek haphe, touch = inability to (feel) touch.
Anastrozole
An oral antiestrogen. Anastrozole inhibits the enzyme aromatase in the adrenal glands that produces the estrogens (estradiol and estrone) and thereby lowers their levels. Brand name: Arimidex. See also: Aromatase inhibitor.
Anatomic orientation terms
"In anatomy, certain terms are used to denote orientation. For example, a structure may be horizontal, as opposed to vertical. Some of the terms of anatomic orientation are as follows:
