Although people are afraid of rabies now, they are not as afraid as they were before19th century, because there is a vaccine today. So why was rabies so terrible before the vaccine came out? Rabies is caused by virus infection. The virus has the characteristics of fast propagation, high mutation rate, strong infectivity and difficult extraction. The death rate of rabies caused by it is 100%. People and animals are sick, and many people are bitten by mad dogs. Although this disease is not common, it can't be cured.

Today, all the credit for solving this problem comes from Pasteur's conquest of rabies. /kloc-In the 9th century, a biological genius was born in France. He is Pasteur. He devoted his whole life to scientific undertakings closely related to people's lives. He likes studying biology and is very sensitive to them. In his time, due to environmental factors and other factors, various infectious diseases were not treated, resulting in more and more deaths. In order to improve this situation, Pasteur began to study germs. Under his leadership, he developed something called vaccine, including rabies vaccine.
In order to find a cure for rabies, Pasteur did many experiments and encountered many difficulties, but they were all overcome. In order to collect specimens, he even risked his life, kneeling in front of the mad dog and waiting for it to secrete saliva. Finally, the pathogen was extracted from the diseased animals, and after several generations of culture, the toxicity was reduced and the vaccine was obtained.
His research results saw immediate results, saved the lives of one patient after another and became the first person to cure rabies in the world. Pasteur's conquest of rabies made great contributions to the world.
Introduction of microbiologist Pasteur
Pasteur made many brilliant achievements in his life. This is an introduction to Pasteur.

Pasteur was born in a rural family in France, and his family was poor. When he was a child, he received a general education and liked to ask all kinds of strange questions, but his grades were not particularly good, so his teachers didn't like him very much, but his personality highlighted his innovative thinking. He liked studying nature since he was a child, which paved the way for his later success.
He became a teacher after graduating from high school. However, out of his love for scientific research, he was not satisfied with this. He continued the college entrance examination, and then went to the best normal university in France to continue his research. After graduation, he went to the laboratory to do research. Fortunately, someone discovered his talent, left him and started his formal scientific research work.
Pasteur first engaged in chemical research. He discovered the isomerism of tartaric acid, but he was not satisfied with it, and then turned to biological research. The first research project is the cause and solution of wine souring. He discovered the influence of microorganisms on food and summarized the relationship between temperature, environment, fermentation components and wine quality. Since then, he mainly studied microorganisms, discovered yeast successively, and developed chicken cholera vaccine, anthrax vaccine and rabies vaccine, which solved the silkworm disease that was a headache for industrial producers. He also created the "bus disinfection method" that continues to this day, and painted a rich and colorful stroke on Pasteur's introduction.
Pasteur not only achieved great success in science, but also was an upright patriot. When France was invaded, he refused the honor given by the aggressor country. His success has been recognized all over the world, and even the president personally helped him and thanked him in the name of the country. Pasteur died at the age of 73 and was buried with students and senior officials from many countries. This concludes Pasteur's introduction.
Brief introduction of louis pasteur
As an outstanding figure in modern microbiology and chemistry, louis pasteur has made great achievements in the world. Just as classical mechanics was pioneered, Pasteur also played a pioneering role in microbiology. The giant of science has been exploring the truth and value of science all his life.

Speaking of louis pasteur's name, many people will feel a little strange, but in fact, he has many well-known achievements. He initiated microbial physiology at that time by studying the habits, characteristics, nutrition and reproductive characteristics of microorganisms, and made a series of explorations and discoveries in this regard. It is its research on microbiology that makes human beings more capable of defeating diseases such as rabies and cholera. One thing reported is that Pasteur diagnosed and solved the problem of wound infection for the British doctors at that time. This is also an important achievement of bacteriology.
Pasteur was called "the father of modern bacteriology" by later generations because of his research and contribution to bacteriology. In fact, just like the name "the father of microbiology", these are the fruits of his lifelong efforts. As the son of an ordinary French worker, Pasteur, who was born in poverty, did not give up his dream. Instead, we should give full play to our intelligence and devote ourselves to scientific research and exploration.
It is precisely because louis pasteur did not stop his research after he studied the fermentation problem and established his position in academic circles that he achieved such achievements and influenced the world today.
