Text С. The Founder of Virology
Dmitry losiphovitch Ivanovsky, a prominent Russian scientist, was born in 1864. In 1888 he graduated from Petersburg University and began to study the physiology of plants and microbiology.
When D. I. Ivanovsky was investigating the tobacco mosaic disease (мозаичная болезнь табака) he was able to come to the conclusion that this disease occurred due to a microscopic agent, many times smaller than bacteria.
To prove this phenomenon D. I. Ivanovsky had to make many experiments on various plants. He had to pass the Juice of the diseased plant through a fine filter which could catch the smallest bacteria. At that time a little over 70 years ago everybody considered that bacteria were the smallest living organisms. But when D. I. Ivanovsky had completed to pass the juice through a fine filter, he was able to come to conclusion that the living organisms smaller than bacteria existed in the environment, because when he introduced the filtrate of the diseased plants to healthy ones they became infected.
Before D. I. Ivanovsky nobody had been able to prove the existence of viruses. Dmitry losiphovitch Ivanovsky was the first scientist who was able to establish the new branch of microbiology—virology.

XV. Read and entitle Text D. Describe how bacteria invade the organism:
Text D
If there are no wounds on the skin no bacteria can invade it. But if any smallest wound exists then bacteria can pass into the tissue. The thin membranes about the eye, in the nose and throat have less protective properties against bacterial invasion and infection may often develop in these points.
The way by which a microorganism enters the human body is an important factor to determine the occurrence of any disease. Certain bacteria can persist and develop in the human body only coming into contact with the respiratory tract, others through contact with the mucus of the intestines.
The skin and mucus membranes of the body have a large number of bacteria, some of them are highly pathogenic in a favourable environment. The spread of these bacteria is controlled by the skin and phagocytes fighting against the invaders.
