Disease in Ancient DNA Samples Hansen's disease or Leprosy is one of the worst epidemics which created major health problems in the world even during ancient periods. It is still prevailing in some parts of the world even though the majority of the countries successfully blocked the spreading this disease. One of the major problems associated with leprosy is the fact that this disease has the ability to destroy the beauty of a person cause huge physical and psychological pains in the minds of the victims. “ From ancient time leprosy has been regarded as a terrifying, stigmatized disease; nevertheless, its cause remained unidentified up to the late 19th century” (Azizi & Bahadori, p.
Mycobacterium leprae, the etiological agent of leprosy was identified by G. Hansen in the 19th century and therefore leprosy is also called as Hansen's Disease (Alter et al. “ It is transmitted through mucous secretions of a deceased individual. The symptoms of the disease include hypopigmented lesions enlarged peripheral nerves and skin anesthesia” (Piris et al. 125) “ Hansen's disease, also known as leprosy, remains an important public health problem throughout the world. The causative microbe in Hansen's disease is Mycobacterium leprae, an acid-fast organism that is difficult to grow in vitro” (Legendre et al.
Hansen's disease is one of the oldest diseases reported in the history. Holy Bible, both New Testaments and Old Testaments, say many incidents related to the leprosy patients. As in the case of AIDS or HIV, it is difficult to predict how leprosy evolved in this world. Medical scientists are currently analyzing ancient DNA samples to find out more details about the origin of Hansen's disease. Anuja et al (2011) pointed out that “ tissue changes in oral tissues do happen in some cases of leprosy and the causative organism Mycobacterium leprae can be demonstrated” (Anuja et al.
In other words, the contribution of Mycobacterium leprae in causing leprosy is proved beyond doubt by different studies. However, the details about how Mycobacterium leprae evolved in this world is still unknown and more researchers are necessary to find out the details about its evolution. This paper analyses the available literature to know more about Hansen's Disease in Ancient DNA Samples. DNA is the molecule that contains the genetic information needed for a living organism to develop and function.
When an organism dies the DNA molecules start to degrade, breaking up into
