It was called Bacterium pestis before 1900, Bacillus pestis until 1923, and Pasteurella pestis up to 1970, when it received its final name, Yersinia pestis. [3] The plague bacillus develops better at lower temperatures, so Yersin's less well-equipped lab turned out to be an advantage in the race with Kitasato, who used an incubator. He had widespread interests—astronomy, radio, photography, and French automobiles—that he pursued until his death at 77 in 1943.. Three pandemics of bubonic plague have ravaged mankind, causing horrific mortality and widespread social devastation. Although the mechanisms were unclear, the disease seemed contagious, and a common response was to avoid the sick. Demanding payment for treating an invalid is rather like saying, ‘Your money or your life.’” Accordingly, after his work with plague, he became involved in other pursuits. The healthy rat contracted plague. En 2014, Alexandre Yersin a été nommé à titre posthume citoyen d'honneur d… © Institut Pasteur. Pasteur a aussi développé les vaccins contre le choléra des poules et la maladie du charbon. He inoculated a mouse and saw a similar bacterium in another patient. Albert Calmette (1863-1933), later famous for developing a vaccine against tuberculosis (Bacillus-Calmette-Guerin [BCG]), had been sent from the Pasteur Institute in Paris to found a branch in Saigon. Yersin’s house and the cupola of his observatory, in Nha Trang. For the 2017-2018 term, the members are: Professor Tuan V. NGUYEN, University of New South Wales, Sydney, Australia. Yersin shrine at the Buddhist Lihn Son Phap Pagoda near Nha Trang. Yersin had always been ambivalent about medical practice. In 1894, an obscure microbiologist in Hong Kong finally eliminated that uncertainty. The illness began suddenly with fever, usually followed shortly by the development in the groin, thigh, axilla, or neck of an excruciatingly painful swelling, called a “bubo” (Greek for “groin”). A third concept was that it arose from a malign configuration of the planets. Quelques considérations sur le bétail humain en Asie du Sud-Est », p. 11-52, cartes, photos From 1883 to 1884, Yersin studied medicine at Lausanne, Switzerland; and then at Marburg, Germany and Paris (1884–1886). He participated in one of the Auguste Pavie missions. He developed a laboratory there, planted rubber trees, and sold its latex to the Michelin Company. Yersin was born to a family originally from France. Alexandre Yersin (terlahir dengan nama Alexandre Emile Jean Yersin; lahir 22 September 1863 - meninggal 1 Maret 1943) adalah seorang dokter dan bakteriolog asal Swiss dan merupakan warga naturalisasi Prancis. Sometimes, it drained pus, which was a favorable sign. In 1915, after the outbreak of World War I, he determined to have Indochina make its own quinine, which comes from the bark of cinchona trees. The Linh Son Phap Pagoda, in the village of Suôi Cat, some 20 km from the Nha Trang Bay, contains a shrine to Yersin, whith his portrait, the object of a fervent cult. Dia menjadi terkenal karena jasanya menemukan bacillus yang menjadi penyebab penyakit pes bubo, yang kemudian penyakit tersebut diberi nama sesuai dengan namanya demi … He inoculated agar, and the isolates, when injected into mice and rats, produced plague. Japanese microbiologist He is remembered as the co-discoverer of the bacillus responsible for the bubonic plague or pest, which was later named in his honour: Yersinia pestis. Kitasato came to Hong Kong with six assistants and received gracious hospitality from the Scottish doctor James Lowson (1866-1935), who was Superintendent of the Government Civil Hospital. Illuminated vellum, 14th century, You could also do it yourself at any point in time. One option, especially for the wealthy, was to flee. The slides that Lowson and Kitasato sent to The Lancet and British Medical Journal, however, seemed to show two organisms: small bacilli, but also diplococci. The third, beginning in western China, appeared in Hong Kong in 1894. These three explanations often overlapped, as when Shakespeare alluded to “a planetary plague, when Jove/Will o’er some high-viced [ie, vice-ridden] city hang his poison/In the sick air” (Timon of Athens IV; iii: 110-112). When the governor-general Jules Brévié visited Da Lat he told a racially mixed set of students at the Lycée Yersin on 12 July 1938, At points on the globe where there is contact between different races an … All rights reserved. Some thought that it resulted from “miasma,” air polluted by noxious substances that could enter the human body through the skin or respiratory tract. Back in Nha Trang, where he witnessed the Japanese occupation of Indochina, he died peacefully on February 27, 1943, at the age of seventy-seven. Travelling through heavy rain, he only reached the plateau of Djiring, where he first met the Montagnards, the inhabitants of the Vietnam highlands. Although small in stature, he possessed the extraordinary stamina and tenacity required to confront the challenges of these hazardous and physically demanding journeys. When a rat with plague, but no fleas, was similarly housed with healthy rats, no infection occurred. Just better. Cough, dyspnea, and bloody sputum could occur and signified imminent demise. Yersin left Europe in 1890 to serve as a physician aboard steamships operating off the coast of Indochina and soon began his four-year exploration of the central region. He also encountered hostility from some village chiefs, who denied passage through their territories. On May 30, 1940, at the end of his last visit, he took a midnight plane destined for Saigon just six hours before the invading German army closed the Paris airport. © Institut He became interested in astronomy, radio, photography, and French automobiles, buying successive models, which he drove in Vietnam. There, an obscure 30-year-old microbiologist, Alexandre Yersin, who had trained in Paris with Louis Pasteur and Emile Roux, discovered the cause of plague and identified its vector as rats. British soldiers from the Staffordshire Regiment cleaning plague-infested houses in Alexandre Emile John Yersin (Lavaux, cantón de Vaud, Suiza; 22 de septiembre de 1863-Nha Trang, Vietnam; 1 de marzo de 1943) fue un médico y bacteriólogo franco-suizo.Junto con el médico y bacteriólogo japonés Kitasato Shibasaburō, es recordado como el codescubridor de los bacilos responsables de la peste bubónica, la cual fue llamada en 1970 en su honor (Yersinia pestis). Many victims reeked from the stench of their breath or because of putrid discharges from their sores or nasal cavities. Many people, undoubtedly, were courageous and humane, but most probably became inured to death. The historian Procopius (500-565), who was in Constantinople when the plague struck in 542, wrote, “All the customary rites of burial were overlooked… it was sufficient if one carried… the body of one of the dead to the parts of the city which bordered on the sea and flung him down; and there the corpses would be thrown upon skiffs in a heap, to be conveyed wherever it might chance.”. He persuaded Yersin to join the French Colonial Health Service, which, he argued, would help support further explorations. In 1888, he became a citizen of France, a requirement to practice medicine there. Having decided to stay in his country of adoption, he participated actively in the creation of the Medical School of Ha Noi in 1902, and was its first director, until 1904. After a year, he began sailing between Saigon and Haiphong along the coast of Vietnam. To install click the Add extension button. He took chronometers, altimeters, and compasses to map the areas and wrote detailed notes about the geography, flora, fauna, and people seen along the way. From 1895 to 1897, Yersin further pursued his studies on the bubonic plague. Another reaction was to isolate the ill. The pandemic eventually spread to Europe and continued as periodic outbreaks until it ended and plague mysteriously vanished in the 8th century. Pepys, noticing a corpse being carried away, responded, “Lord, to see what custom is, that I am come almost to think nothing of it.” These reactions of fear, flight, indifference, bizarre behavior, and inhumanity arose primarily because the cause of plague remained unknown. [1][2] However, a thorough analysis of the morphology of the organism discovered by Kitasato has determined that "we are confident that Kitasato had examined the plague bacillus in Hong Kong in late June and early July 1894", only days after Yersin announced his own discovery on 20 June. Emeritus Professor Nu Viet VU, University of Geneva, Switzerland Emeritus Professor Ezio GIACOBINI, University of Geneva, Switzerland Emeritus Professor Jean … In Ha Noi, a French lycée has his name. His last exploration was a three-month trip in 1894 from the sea westward to the Central Highlands, following a varying northward course that finally ended at the coast in Da Nang. 2014;36:528-539 (see French abstract on page 539). Accused of poisoning wells and rivers, nearly 1000 Jews were burned in Strasbourg in 1349, and other Jewish communities in the Rhineland were almost completely annihilated. Yersin then traveled south on a river boat to Phnom Penh before returning to Saigon. Physicians during this pandemic used the Latin word pestis (“pestilence” in English) for the disease or “plague,” from a Greek word meaning “stroke” or “blow.” A common term was the “Great Mortality.” Only two centuries later was the illness first called the Black Death, not referring to the dark skin lesions that can occur, but apparently because of a Scandinavian mistranslation from the Latin of atra mors, for in its original source atra meant “terrible,” not “black.” Despite this error, the outbreak from 1346-1353 has been called the Black Death since. Photo by He returned to Nha Trang later that year, and when plague recurred in 1896, he tried the therapy on an 18-year-old Chinese seminary student on June 26. While in Hong Kong, Yersin was helped in his research by an Italian priest of the PIME order named Bernardo Vigano. In addition to transmission via fleas and inhalation of Y pestis, plague can occur from direct handling of infected animal tissues or by ingesting the organism. Relations are a factor of your evolution and your transformation, which you accept serenely. Soon afterwards (1890), he left for French Indochina (current Vietnam, Laos and Cambodia) in Southeast Asia as a physician for the Messageries Maritimes company, on the Saigon-Manila line and then on the Saigon-Haiphong line. In 1889, he completed research on an experimental form of septicemic tuberculosis for his doctoral thesis, winning a bronze medallion from the Faculty of Medicine of the University of Paris. In addition, he discovered and characterized its exotoxin and, with Emil Behring (1854-1917), produced tetanus antitoxin. Boccaccio wrote that many lived moderately and abstemiously, but others “maintained that the surest medicine for such an evil disease was to drink heavily, enjoy life’s pleasures…satisfying their appetites by any means available….” Searching for causes, some blamed the disease on others. Alexandre Emile Jean Yersin ( 1863 – 1943) va ser un metge i bacteriòleg suís nacionalitzat francès. On June 23, he demonstrated that rats dying in the streets of Hong Kong, like humans, had buboes filled with enormous numbers of the same bacilli. In February1893, he began a seven-month trip from Saigon to explore the southern part of the Central Highlands, heading northeast and discovering along the way the fertile plateau of Lang Bian. In 1888 he received his doctorate with a dissertation titled Étude sur le Développement du Tubercule Expérimental and spent two months with Robert Koch in Germany. Finding the appropriate growing conditions was challenging, but, using seeds that he had acquired in Java, his efforts eventually succeeded. He provided cadavers and assisted with his quest to find a remedy for the plague. © Institut Pasteur. In a letter, he wrote: “I take great pleasure in treating those who come to me, but I should not like to make medicine my living. A probable explanation for Kitasato’s confusing initial reports is that another bacterium, possibly Streptococcus pneumoniae, contaminated his cultures. Xenopsylla cheopsis, the common rat flea, At about the same time, flagellants, condemning them- selves, Jews, and humanity in general, traveled through Europe exhorting repentance and beating themselves bloody with knotted whips to propitiate God’s anger. Pasteur was impressed with Yersin’s great scientific qualities, characterizing his habits of silent labor as almost ascetic. Another bacteriologist, the Japanese physician Kitasato Shibasaburō, is often credited with independently identifying the bacterium a few days earlier, but may have identified a different bacterium and not the pathogen-causing plague. It was the first recorded use of antiplague serum, and the patient survived, as did 21 of 23 other victims who received his remaining supply. They demonstrated that the disease’s clinical manifestations arose from a toxin, which they identified in the urine of infected patients.
