Mosquitoes and the Nobel Prize

Li Dabin

Some people say that equality before the law is somewhat unreliable, but equality before mosquitoes is true. It is said that all over the world, from princes and nobles to ordinary people, no one has ever been bitten by mosquitoes in his life.

Mosquito bites not only affect people's sleep and bring a lot of inconvenience to life, but also are a secret and extremely cruel biological war. According to rough statistics, since the beginning of human history, small mosquitoes have claimed tens of millions of fresh lives again and again, even affecting the rise and fall of a country, the outcome of a war and the progress of a project. This grim and terrible fact has been kept in the dark for a long time, and it was not until the 19th century that an outstanding scientist exposed the secret.

Of course, the great harm of mosquitoes is not directly caused by its small mouth, but through a malaria disease it spreads. The disease spreads quickly, and the course of the disease is relatively hidden. It is often intermittent chills and fever, which destroys a lot of red blood cells and makes the body gradually fail until death. According to historians' research, the Roman Empire in the 5th century was once very powerful, but due to the long-term and large-scale epidemic of malaria, the army could not fight and the people could not produce, which led to the decline of national strength, unable to resist the attack of the Germanic nation and finally perished. After the German army captured Rome, it was too late to celebrate the victory, so it was impossible to control the epidemic of malaria, and finally it had to abandon the city. During the American Civil War, when the northern allied forces were preparing to attack Vicksburg, Mississippi, an important stronghold of the Confederate army, the military operation was seriously frustrated because of the large-scale epidemic of malaria. Malaria also almost destroyed the Panama Canal Project.

The harm of malaria transmitted by mosquitoes is so tragic that scientists will pay attention to it. In this biological war against malaria, the French military doctor Laffron should be mentioned first. In 1878, the military sent him to the French colony Algeria to study malaria there. After Laffron arrived in Algeria, he lived up to expectations and dissected and observed the bodies of many malaria victims in depth and in detail. After more than two years of repeated comparison and careful study, it was finally confirmed on November 5, 188 that malaria was caused by a single-celled organism named protozoa produced in the red blood cells of patients. The next question is how this protozoan gets into red blood cells and how it is passed from one patient to another.

The baton of this research was passed to the British doctor Ronabe? Ross has it.

Ross's father is a general of the British colonial army in India. Ross was born in India. After returning to the UK to finish medical school, he went to India to practice medicine in 1881. At that time, both Indian residents and British troops were tortured by malaria, so Ross paid great attention to malaria research. Since Laffron had already published his findings, Ross thought that his research goal should be the relationship between mosquitoes and protozoa. He captured, dissected and observed countless mosquitoes and did many experiments. On August 2, 1897, he was in a kind of? Anopheles? The kind of plasmodium reported by Lafran was found in his stomach. In 1898, Ross successfully used? Anopheles? Plasmodium in the stomach causes malaria in birds, and it is confirmed that only females? Anopheles? To spread malaria. Originally, he wanted to use the same method to cause human malaria, so as to draw a satisfactory conclusion for his research, but unfortunately he did not succeed. After Ross retired in 1899, the last threshold of his research project was crossed by a group of Italian doctors. They confirmed that mosquitoes sucked plasmodium into the stomach when sucking the blood of malaria patients, and injected plasmodium into the blood of healthy people when biting them, making them suffer from malaria.

In recognition of Ross's outstanding contribution, in 192, the Nobel Prize jury awarded him the Nobel Prize in Physiology and Medicine. Five years later, Laffron also won the Nobel Prize in Physiology and Medicine. Although this award came a little late. But Laffron's achievements have not been buried after all.

although scientists revealed the cause of malaria and its relationship with mosquitoes, by 193, malaria had once again made 1 million people sick and 3 million people died. Later, Dr. Miller, a Swiss chemist, invented DDT to kill mosquitoes, and in 1948 he was awarded the Nobel Prize in Physiology and Medicine. Another Austrian psychiatrist used the high fever at the onset of malaria to treat paralytic dementia caused by tertiary syphilis, and unexpectedly won the Nobel Prize in Physiology and Medicine in 1927.

The tiny mosquito won four Nobel Prizes successively.
