A bacteriologic relapse was defined as a patient who became consistently culture-positive [defined as at least 1 of the following]: a at least 1 sputum mycobacterial culture growing at least 10 colonies of MTB on solid medium; b 2 or more respiratory secretion cultures that are positive for MTB in liquid media; or c any culture from an extrapulmonary site that is positive for MTB during follow-up after successful completion of initial anti-TB treatment.

Other organs, such as the kidneys, spine, or brain may also be involved. TB is primarily spread from person to person in an airborne manner, such as when an infected person coughs or sneezes.

Throughout history, the disease tuberculosis has been variously known as consumption, phthisis and the White Plague. It is generally accepted that the causative agent, Mycobacterium tuberculosis originated from other, more primitive organisms of the same genus Mycobacterium. In , results of a new DNA study of a tuberculosis genome reconstructed from remains in southern Peru suggest that human tuberculosis is less than 6, years old. Even if researchers theorise that humans first acquired it in Africa about 5, years ago, [1] there is evidence that the first tuberculosis infection happened about 9, years ago.

It also spread to domesticated animals in Africa, such as goats and cows. Seals and sea lions that bred on African beaches are believed to have acquired the disease and carried it across the Atlantic to South America. Hunters would have been the first humans to contract the disease there. Scientific work investigating the evolutionary origins of the Mycobacterium tuberculosis complex has concluded that the most recent common ancestor of the complex was a human-specific pathogen , which underwent a population bottleneck.

Analysis of mycobacterial interspersed repetitive units has allowed dating of the bottleneck to approximately 40, years ago, which corresponds to the period subsequent to the expansion of Homo sapiens sapiens out of Africa. This analysis of mycobacterial interspersed repetitive units also dated the Mycobacterium bovis lineage as dispersing approximately 6, years ago, which may be linked to animal domestication and early farming. There have been recent references to farming.

Human bones from the Neolithic show presence of the bacteria. There has also been a claim of evidence of lesions characteristic of tuberculosis in a , year old Homo erectus fossil, although this finding is controversial.

Jump to content. Tuberculosis TB is an infection caused by slow-growing bacteria that grow best in areas of the body that have lots of blood and oxygen. That’s why it is most often found in the lungs. This is called pulmonary TB. But TB can also spread to other parts of the body, which is called extrapulmonary TB. Treatment is often a success, but it is a long process. It usually takes about 6 to 9 months to treat TB. But some TB infections need to be treated for up to 2 years.

Pulmonary TB in the lungs is contagious.
