Techniques Used For the Diagnostic of Ancient Tuberculosis Remains

Summary Tuberculosis is one of the most contagious infections today caused by a group of closely related species contained in the Mycobacterium tuberculosis group (MTBC). Molecular studies targeting tuberculosis affecting human bodies are important for understanding the evolution of specific genomic loci associated with pathogenicity. The purpose of this review is to explain some techniques that help confirm the persistence of pathogens in human archaeological ruins.

Tuberculosis has existed in humans since ancient times. The earliest definitive detection of Mycobacterium tuberculosis included evidence of disease in the bison's traces of about 17,000 years ago during pregnancy. However, it is unknown whether tuberculosis is derived from cattle and spreads to humans or is different from general ancestry. Comparison of MTB genes in humans with MTBCs in animals indicates that humans did not get MTBCs from animals during domestication as previously thought. Both types of tuberculosis share a common ancestor and may infect humans even before the Neolithic Revolution. Skeletal remains show that prehistoric humans (4000 BC) had tuberculosis, researchers found that Egyptian mummified spines fell from 3000 BC to 2400 BC. Genetic studies have shown that tuberculosis exists in the US AD in the US

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (1) and remains the leading cause of infectious disease deaths worldwide (2). There is clear evidence that the incidence of tuberculosis is increasing. Between 2000 and 2020, about 1 billion people are newly infected with tuberculosis, 200 million people are predisposed to develop this disease, and 35 million people are estimated to die from tuberculosis (3). Coughing, sneezing, and inhalation of droplets from people infected with tuberculosis may develop by infection with tuberculosis (4). A less common infection route is the gastrointestinal tract (11) by digesting milk and skin wounds infected with Mycobacterium tuberculosis and infected Mycobacterium tuberculosis, like pathologists and laboratory technicians treating tuberculosis specimens. Tuberculosis may infect only people from close contact with respiratory infected air (8). It does not infect handshake or contact with infected people (9)
