Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [1] [2] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Tuberculosis classification system. The current clinical classification system for tuberculosis (TB) is based on the pathogenesis of the disease. [1] Health care providers should comply with local laws and regulations requiring the reporting of TB. All persons with class 3 or class 5 TB should be reported promptly to the local health department.
Tuberculosis management. Tuberculosis management describes the 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 ...
A definitive diagnosis of tuberculosis can only be made by culturing Mycobacterium tuberculosis organisms from a specimen taken from the patient (most often sputum, but may also include pus, CSF, biopsied tissue, etc.). [1] A diagnosis made other than by culture may only be classified as "probable" or "presumed".
In addition, between 1851 and 1910, around four million died from TB in England and Wales – more than one third of those aged 15 to 34 and half of those aged 20 to 24 died from TB. By the late 19th century, 70–90% of the urban populations of Europe and North America were infected with the Mycobacterium tuberculosis , and about 80% of those ...
Multidrug-resistant tuberculosis ( MDR-TB) is a form of tuberculosis (TB) infection caused by bacteria that are resistant to treatment with at least two of the most powerful first-line anti-TB medications (drugs): isoniazid and rifampicin. Some forms of TB are also resistant to second-line medications, and are called extensively drug-resistant ...
Infectious disease. Latent tuberculosis ( LTB ), also called latent tuberculosis infection ( LTBI) is when a person is infected with Mycobacterium tuberculosis, but does not have active tuberculosis (TB). Active tuberculosis can be contagious while latent tuberculosis is not, and it is therefore not possible to get TB from someone with latent ...
Isoniazid. Isoniazid, also known as isonicotinic acid hydrazide ( INH ), is an antibiotic used for the treatment of tuberculosis. [4] For active tuberculosis, it is often used together with rifampicin, pyrazinamide, and either streptomycin or ethambutol. [5] For latent tuberculosis, it is often used alone. [4]
