A to Z of tuberculosis (Letter A)
« on: November 08, 2016, 21:32:38 PM »





A


Mycobacteria that when stained, retain color even after they have been washed in an acid solution; may be detected under a microscope in a stained smear.


Following the recommended course of treatment by taking all the prescribed medications for the entire recommended time.


The first level in the hierarchy of TB infection-control measures; managerial measures that reduce the risk for exposure to persons who have or are suspected to have TB disease.


Negative side effect resulting from the use of a drug (for example, hepatitis, nausea, headache).


acquired immunodeficiency syndrome, a condition in which the immune system is weakened and therefore less able to fight certain infections and diseases; AIDS is caused by infection with the human immunodeficiency virus (HIV).


The small air sacs of the lung that are at the end of the airway; when droplet nuclei reach these air sacs, TB infection begins.


The inability to react to a skin test because of a weakened immune system, often caused by HIV infection or severe illness .


protein substances that can produce an immune response (such as CFP-10, ESAT-6, or those in PPD)
antiretroviral therapy


A lifelong combination drug treatment to suppress HIV and improve the quality and length of life for a person living with HIV/AIDS

B


Tests done in a mycobacteriology laboratory to aid diagnosis of TB disease; includes examining a specimen under a microscope, culturing the specimen, and testing for drug susceptibility.


A tuberculin skin test (TST) given to employees or residents in certain facilities when they start their job or enter the facility (see TB testing program and two-step testing).


A positive reaction to a TST, due to a boosted immune response from a skin test given up to a year earlier; occurs in people who were infected a long time ago and whose ability to react to tuberculin has lessened. Two-step testing is used in TB testing programs to tell the difference between boosted
reactions and reactions caused by recent infection (see booster phenomenon and two-step testing).


A phenomenon in which people (especially older adults) who are skin tested many years after becoming infected with M. tuberculosis may have a negative reaction to an initial TST, followed by a positive reaction to a TST given up to a year later; this happens because the first TST boosts the immune response. Two-step testing is used in TB testing programs to tell the difference between boosted reactions and reactions caused by recent infection (see two-step testing).


A procedure used to obtain pulmonary secretions or lung tissue with an instrument called a bronchoscope; used only when patients cannot cough up sputum on their own and an induced specimen cannot be obtained.
