Tuberculosis (TB) is an airborne microbial disease and it is one of the top contributors of deaths across the globe. It was found to be contracted from the pathogen Mycobacterium tuberculosis by Robert Koch in 1882 (Fogel, 2015). This discovery was aided by Jean-Antoine Villemin, a french doctor in the 1800’s, who found the tuberculosis disease to be contagious (Cambau and Drancourt, 2014). With Koch’s discovery in mind even if a person is infected with Mycobacterium tuberculosis there is only a small chance of 10% that they will eventually develop TB (Lee, 2015). (MAP) There are different types of TB that a person can develop a couple examples are latent and active. Latent TB is where there are no physical symptoms of the disease, making it hard to diagnose unless the correct tests are carried out for example chest x-rays. This type is not contagious and if not treated can eventually become active and contagious. Active type of TB is where the bacteria infects different organs, mainly the lungs causing this type to be contagious. TB has been found to come from the genus Mycobacterium. It was first thought that through the taming and keeping of cattle around 10,000-25,000 years ago allowed the bacteria to transfer from the livestock and infect humans. This would be where the bacteria would grow and evolve in the new host and become close to the bacterial species that we see today that can develop into Tuberculosis (Smith, 2003). Although, further research has shown
