NEW TUBERCULIN Meaning and
Definition
-
New tuberculin refers to a type of diagnostic substance or antigen that is used in the detection and testing of tuberculosis (TB). Tuberculosis is an infectious bacterial disease primarily affecting the lungs, caused by the bacterium Mycobacterium tuberculosis. New tuberculin represents an updated and improved version of the tuberculin protein derivative that was developed by Albert Calmette and Camille Guérin in the early 1900s.
The new tuberculin solution is derived from a culture of the Mycobacterium tuberculosis bacteria which has been deactivated. It is then processed to extract specific components of the bacteria to be used as an antigen. When administered via a skin test, the new tuberculin solution elicits an immune response in individuals who have been exposed to or previously infected with TB. This immune response leads to the development of a raised, red bump at the site of injection, known as a tuberculin skin test reaction or an induration.
The size of the induration that forms in response to the skin test is measured and interpreted by a healthcare professional to determine if an individual has been infected with TB or has developed immunity due to prior exposure. This information helps in diagnosing TB, identifying latent TB infections, and guiding appropriate treatment and preventive measures.
New tuberculin represents an advancement in the diagnosis of tuberculosis, providing a more refined and accurate tool for detecting this infectious disease.

Koch, TR, residual tuberculin; an emulsion is made of finely triturated tubercle bacilli in distilled water or physiological salt solution, which on centrifugation separates into an upper translucent fluid layer (TO, tuberculin ober) and a muddy sediment (TR, tuberculin rest); the latter is dried, again triturated, emulsified, and centrifugated, and this process is repeated until only an opalescent fluid is obtained; glycerin is now added in quantity to make a 20 per cent. solution which is then ready for use; this is intended to immunize against the bacilli.

Etymology of NEW TUBERCULIN
The word "new tuberculin" is a medical term used to describe a specific type of tuberculin, which is a protein derivative that is used in diagnosing tuberculosis. The etymology of the term can be broken down as follows:
1. New: The word "new" originates from the Old English word "neowe" and is related to the Proto-Germanic word "newjaz". It has remained largely unchanged in its meaning, referring to something that is recently made, discovered, or introduced.
2. Tuberculin: The word "tuberculin" originated from the Latin word "tuberculum", meaning "a small swelling" or "a little lump". In medical terminology, it specifically refers to the extract derived from tubercle bacilli, which is used to test for tuberculosis.
