Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, [7] is a contagious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. [1] Tuberculosis generally affects the lungs , but it can also affect other parts of the body. [ 1 ]
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB. The medical standard for active TB is a short course treatment involving a combination of isoniazid , rifampicin (also known as Rifampin), pyrazinamide , and ethambutol for the first two months.
However, beginning with the first antibiotic treatment for TB in 1943, some strains of the TB bacteria developed resistance to the standard drugs through genetic changes (see mechanisms.) [2] [4] [5] Currently the majority of multidrug-resistant cases of TB are due to one strain of TB bacteria called the Beijing lineage.
Other parts of the medical history include prior TB exposure, infection or disease and medical conditions that increase risk for TB disease such as HIV infection. Depending on the sort of patient population surveyed, as few as 20%, or as many as 75% of pulmonary tuberculosis cases may be without symptoms. [2]
After weeks of allowing the bacteria to grow the plate is checked for clear areas around the disk. If there is a clear area, the drug has killed the bacteria and most likely the bacteria are not resistant to that drug. [citation needed] As Mycobacterium tuberculosis evolved new strains of resistant bacteria were being found such as XDR-TB. The ...
Extensively drug resistant tuberculosis is tuberculosis that is resistant to isoniazid and rifampicin, any fluoroquinolone, and any of the three second line injectable TB drugs (amikacin, capreomycin, and kanamycin). [1] TDR-TB has been identified in three countries; India, Iran, and Italy. The term was first presented in 2006, in which it ...
Antibiotic therapy and corticosteroids [3] Tuberculous meningitis , also known as TB meningitis or tubercular meningitis , is a specific type of bacterial meningitis caused by the Mycobacterium tuberculosis infection of the meninges —the system of membranes which envelop the central nervous system .
An example of a tuberculosis (TB) infection that comes under control: M. tuberculosis cells are engulfed by macrophages after being identified as foreign but, due to an immuno-escape mechanism peculiar to mycobacteria, [4] TB bacteria block the fusion of their enclosing phagosome with lysosomes which would destroy the bacteria. Thereby TB can ...
