Summary of Audiolibro: Los cazadores de microbios (capítulo 4)

00:00:00 - 00:10:00

In this video, Dr. Robert Koch discusses how he discovered that microorganisms cause diseases, and how he developed the theory that tuberculosis is caused by a bacterium. He also shows how he used microscopy to study these microorganisms and how he developed a method of curing tuberculosis using fresh killed animals. Finally, he talks about how his discoveries have led to improved medical treatments for tuberculosis.

• 00:00:00 In this video, Dr. Robert Koch discusses how he discovered the cause of the carbunco, a fatal disease that affected livestock and people in Europe in the mid 1800s. He describes a method for contagion using a needle and a piece of bone from an animal that had died of the carbunco. He repeats this process eight times with success, and is finally able to prove that the bacillus causing the carbunco is alive and multiplies through filamentous growth.

• 00:10:00 In this video, a brilliant professor of Berlin has successfully infected rabbits with tuberculosis and Koch began working to color the material of the dead worker's clothes into the various colors of a rainbow in an effort to scare the rabbits away. However, the rabbits didn't seem to be scared away and began to die in droves. Coche eventually discovered the same black, greasy spores in the worker's body that he found in the obstructed cages of the rabbits and found them for the first time at aBerlin hospital. He then went around the hospitals in Berlin asking for bodies with tuberculosis to be donated for study. He spent days and nights in the death camps of tuberculosis, conducting experiments with blood serum collected from freshly slaughtered cows. He eventually succeeded in culturing tuberculosis bacteria in gelatina and published his findings in a series of papers in 1882. However, his work was largely ignored and he died from tuberculosis himself in 1884. His work on tuberculosis led to the development of the tuberculosis vaccine and helped to eradicate the disease.
