Text B. Robert Koch

Robert Koch is a prominent German bacteriologist, the founder of modern microbiology. He was born in 1843, died in 1910. When Koch became a doctor he carried on many experiments on mice (мышах) in a small laboratory. In 1882 Koch discovered tuberculosis bacilli. In his report made in the Berlin Physiological Society Koch described in detail the morphology of tuberculosis bacilli and the ways to reveal them. Due to his discovery Koch became known all over the world. In 1884 Koch published his book on cholera. This book included the investigations of his research work carried out during the cholera epidemic in Egypt and India. From the intestines of the men with cholera Koch isolated a small comma-shaped (в виде запятой) bacterium. He determined that these bacteria spread through drinking water. In 1905 Koch got the Nobel prize for his important scientific discoveries.
