Madera Community College Center Tuberculosis Raul Sosa Mendoza Biology 3, Mrs. Abou Naoum April 19, 2016 Introduction One of the top infectious diseases world wild, tuberculosis has plagued humanity for centuries. Tuberculosis is caused by a bacterium, that bacteria attacks the lungs but can also attack and spread to other body parts. Prior to medical advances not much was known about this tuberculosis disease. It is believed that Tuberculosis (or TB for short) has been around for six thousand years. Scientist theorized that TB could have first infected humans roughly five thousand years ago, from contact with infected domesticated animals and spreading along trade routes. Evidence of TB causing bacterium hasâ⬠¦show more contentâ⬠¦If one only considers the productive middle-age groups, tuberculosis carries away one-third, and often more(Tuberculosis). After bringing awareness about how deadly the disease was, Koch described to his audience of how he invented a new staining method. Koch wanted his audience to see what he had found, so he brought his laboratory to the lecture room: jars of tis sues, glass slides, microscopes, etc. Koch compared two specimens infected with TB, one of a guinea pig and a human who had died from blood-borne TB. That the cultures of bacteria taken from the infected guinea pigs were identical to that of the human. The discovery stunned the audience and news of the findings spread. Robert Koch was later awarded the nobel prize for his investigations and discovery related to tuberculosis in 1905. Although Robert Koch s findings were ground breaking, Tuberculosis was still killing millions of people annually. It has been estimated that the annual death rate during Koch s discovery was seven million people and from 1700 to 1900 tuberculosis was responsible for the deaths of approximately one billion human begins (Robert Koch and Tuberculosis). Further research had to be pursued in order to eradicate TB. Scientist observed that the bacteria did not survive long in enriched soil. It was discovered that fungi in the soil suppressed the growth of the bacteria. In 1943 American, together with co workers, Selman Waksman
