What mark was left by a flea in world culture? Medical!of the Louse and a flea transfer the hardest diseases, it is possible to tell - deadly. Really heroic efforts of physicians made these diseases curable.
Both louses, and fleas - carriers of an infection which can cause sypny typhus. This disease literally mowed both armies, and the population: where there was a big congestion of people and there were no conditions for care of a body and clothes, typhus epidemic began.
As historians write, from 1917 to 1921 in Russia about 3 million people died from typhus. The number of the diseased was estimated in inconceivable figure - from 25 to 30 million people. Sypna typhus did not disappear after that, incidence was very high both before the Great Patriotic War, and after it. Big danger was constituted by clothes arriving on treatment in military hospital, it was carefully processed regarding extermination of parasites, sometimes burned.
To whom we are obliged that the fatal disease stopped being deadly? Probably, first of all, to Charles Jules Henri Nikol (1866-1936) - the French bacteriologist who established that a carrier of a typhus is the louse clothes (he made the experiments on monkeys). In 1903 he was appointed the director of the branch of Pasterovsky institute in Tunisia, he took up this position to the death. In this branch vaccines and serums against infectious diseases were developed.
One more name - Miriam Rothschild, “The queen of fleas“: the author more than 300 articles and books on entomology and zoology and among other things - the six-volume “Catalog of the Rotshildovsky collection of fleas in the British museum“. She was an honourable doctor of eight universities, the academician of the English Royal Society, the Commodore of the British Empire, the Lady of the British Empire (an equivalent of a knightly rank). She the first studied the mechanism of a jump of fleas (probably, sounds more precisely “described the jump mechanism“ because if mechanics did not know the jump mechanism, they could not create in three hundred years the steel jumping flea before).
The effective vaccine against a typhus was developed by Alexey Vasilyevich Pshenichnov (1900-1975) - the doctor of medical sciences, professor. Application of its vaccine prevented typhus epidemic in the back and at the front during the Great Patriotic War.
Today a situation with incidence of a typhus not catastrophic though local flashes are quite possible. Voshki and flea beetles are not translated. However, information that scientists are anxious with the future of a pubic louse flew recently: the epilation can lead to elimination of a look. It is unlikely it happens in the near future: the fashion comes and leaves. And louses remain.
Unfortunately to get rid of blood-sicking parasites - a task not such simple. Still there are no well-tried and safe chemical remedies for extermination of these insects. Still the human hands supplied with a fine-tooth metal comb remain the most reliable and safe instrument of fight against voshka and flea beetles. Labor-intensive process, but it does not leave to our enemies chances of life.
From childhood memories. Louses were found. That is I do not remember their house, but fight against them was very famous. Mother asked to look with times at her head and spoke: “You will find a louse - you will receive chervonets“. The chervonets was the enormous sum for those times: on it it was possible to buy 10 tickets at cinema. I tried. As could tried. Never found any louse - and it is good. And never received treasured chervonets - and it was bad.
Voshki and flea beetles on march! And how many trails of blood they still will leave in culture of mankind!
