Yersin was born to a family originally from France. From 1895 to 1897, Yersin further pursued his studies on the bubonic plague. During World War I he planted cinchona trees to provide Vietnam with its own supply of quinine to combat malaria. by in 1894. From 1883 to 1884, Yersin studied medicine at Lausanne, Switzerland; and then at Marburg, Germany and Paris (1884â1886). Plague during pregnancy was particularly lethal. When the main rebel chief was later arrested, Yersin witnessed his execution, admiring the impassivity of the victim, who sustained four blows with a sword before decapitation finally occurred. Emeritus Professor Nu Viet VU, University of Geneva, Switzerland Emeritus Professor Ezio GIACOBINI, University of Geneva, Switzerland Emeritus Professor Jean â¦ After meeting Emile Roux (1853-1933), who had developed an antirabies vaccine with Louis Pasteur (1822-1895), Yersin was hired as an assistant in Pasteurâs laboratory.

Disease occurs primarily in three forms: 1) bubonic plague, with fever and swollen, tender, necrotic, and hemorrhagic lymph nodes; 2) septicemic plague, in which bacteremia occurs, but no bubo develops; 3) pneumonic plague, either as a complication of bacteremia or from inhalation of aerosolized bacteria from people with plague pneumonia or from respiratory secretions of infected mammals. Looking back the course of history, Alexandre Yersin, a young 28-year-old French man first put his foot on Nha Trang coast in July 1891. Alexandre Émile John Yersin, popularly known as Alexandre Yersin was a Franco-Swiss bacteriologist and physician. Some became delirious or comatose. Dr Kitasato ShibasaburÅ, also in Hong Kong, had identified a bacterium several days earlier. Another bacteriologist, the Japanese physician Kitasato ShibasaburÅ, 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. Although small in stature, he possessed the extraordinary stamina and tenacity required to confront the challenges of these hazardous and physically demanding journeys. Yersin et sa famille. From the Grandes Chroniques de France, a translation into French of the One option, especially for the wealthy, was to flee. The definitive resolution of this debate is reflected by the nomenclature of the plague bacillus. The result was the charming village of Dalat, which also became a source of vegetables and fruits for the Vietnamese lowlands. Sa mère sâen retourne près de ses parents, dans la banlieue new yorkaise. On doit surtout à Yersin la découverte du bacille de la peste (Yersinia pestis) en 1894, la préparation du premier sérum anti-pesteux et l'étude de la toxine diphtérique. When they next feed, infected fleas regurgitate the bacteria into the bite site, transmitting the bacilli to a new host. Kong Shy, solitary, and intensely private, Yersin found himself more interested in pathology than patient care. The first one began in Egypt with that portion of it known as the âPlague of Justinianâ (541-543), so called because it started in the reign and territory of the Eastern Roman Emperor Justinian (482-565) and because he contracted the disease, which he luckily survived. To install click the Add extension button. From these experiences, he made recommendations for road building, mining, and agriculture. In the London epidemic of 1665, Samuel Pepys (1633-1703) recorded in his diary how the doors of those houses were marked with a red cross and the words âLord have mercy upon us.â Such imprisonment seemed inhumane: âThis disease makes us more cruel to one another than if we are dogs.â In Germany, houses of inhabitants with the plague were marked with black crosses, and the word âPestâ (plague). Numerous accounts concur with Boccaccioâs description: âWhen all the graves were full, enormous trenches were dugâ¦ into which the new arrivals were put by the hundreds, stowed layer upon layer like merchandise in shipsâ¦.â, The traditional rituals surrounding death were commonly abandoned or curtailed. Admiring its tall trees, lakes, waterfalls, and temperate climate, he recommended building a holiday resort there for French civil servants. Earlier, Yersin had traveled to the Far East and had conducted four explorations into French Indochina, primarily in Vietnam, mapping the areas and studying their potential for mining, agriculture, and forestry. He also encountered hostility from some village chiefs, who denied passage through their territories. 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. From there the second pandemic spread to numerous seaports, such as Messina in Sicily, Venice, Genoa, and Marseille, and then throughout Europe, killing more than one-third of the population in five years. Pierre Petit. With just a few horses having bred for experiments, he was the first human manufacturing the specific serum against this dangerous disease. 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 ShibasaburÅ, es recordado como el codescubridor de los bacilos responsables de la peste bubónica, la cual fue llamada en 1970 en su honor (Yersinia pestis). Â© Institut Pasteur â MusÃ©e Pasteur. Another reaction was to isolate the ill. A probable explanation for Kitasatoâs confusing initial reports is that another bacterium, possibly Streptococcus pneumoniae, contaminated his cultures. Uninterested in Parisian life and imbued with enthusiasm for adventure, he resigned from the Pasteur Institute in 1890 to fulfill his inmost dream of emulating the Scottish explorer David Livingstone (1813-1873) by traveling to other continents. En 1899, Yersin introduit l'hévéa dans la région de Nha Trang. 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 âbuboâ (Greek for âgroinâ). Quite the same Wikipedia. This biography provides detailed information about his childhood, life, research, achievements and timeline. Simond placed a rat suffering from plague into a jar and housed a healthy one above him on a screen, close enough for fleas to jump, but far enough to avoid direct contact between the animals. Because of the high altitude and European-like climate, Da Lat became an R&R spot for French officers. He lived there most of the remainder of his life. There was a high school named after him which was built in the 1920s, the LycÃ©e Yersin, aka Grand LycÃ©e (grade 6 to 12), the Petit LycÃ©e (elementary to grade 5), and a university named after him which was built in the 2000s. Yersin had always been ambivalent about medical practice. Â© Wellcome Library, London. 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. Alexandre Yersin poursuit ses études au gymnase de lâAcadémie à Lausanne, où il obtient son diplôme de bachelier ès-lettres le 21 juillet 1883. The third, beginning in western China, appeared in Hong Kong in 1894. Sus trabajos iniciales junto a Émile Roux fueron sobre el bacilo de la difteria, cuya toxina descubrieron en 1886. The picture is likely taken from Bonham Road looking 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. Pasteur. Alexandre Emile Jean Yersin (September 22, 1863âMarch 1, 1943) was a Swiss andFrench physician and bacteriologist.He is remembered as the co-discoverer of the bacillusresponsible for the bubonic plague or pest, which was later renamed in his honour (Yersinia pestis). 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. epidemic the Hong 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. Earlier, in 1886, he and Roux began to study Corynebacterium diphtheriae, the recently identified cause of diphtheria. Yersin tried his hand at agriculture and was a pioneer in the cultivation of rubber trees (Hevea brasiliensis) imported from Brazil into Indochina. In 1888, he became a citizen of France, a requirement to practice medicine there. He arrived on June 15, 1894, with a staff of only two untrained people, one who quickly absconded with Yersinâs money.Yersinâsonly equipment was a microscope, an autoclave, and culture supplies. 11 octobre : Xavier Leroux : compositeur français (â 2 février 1919). These mammals typically acquire Y pestis through bites from fleas, including species other than X cheopsis. Cough, dyspnea, and bloody sputum could occur and signified imminent demise. Furthermore, as he once wrote to his mother, he was unsettled about a career in microbiology: âScientific research is very interesting, but Mr Pasteur is quite right when he said that, unless he is a genius, a man must be wealthy to work in a laboratory and risk leading a miserable existence, even if it does win him a certain scientific renown.â. Dr. Yersin was credited with finding the site for the new town of Da Lat in 1893. Because Kitasato's initial reports were vague and somewhat contradictory, some give Yersin sole credit for the discovery. Plague returned with ferocity in 1346, probably arising in central Asia, traveling along trade routes, and arriving in Crimea in 1347. The Bay of Nha Trang, at the turn of the 19th century. In 1895 he returned to the Institute Pasteur in Paris and with Ãmile Roux, Albert Calmette and AmÃ©dÃ©e Borrel, prepared the first anti-plague serum.

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. He began work in the laboratory of the eminent pathologist Andre Cornil (1837-1908), where he translated German articles for the Professor and performed dissections, including autopsies of rabies victims. Yersin was also able to demonstrate for the first time that the same bacillus was present in the rodent as well as in the human disease, thus underlining the possible means of transmission. The overall case-fatality rate in the first two pandemics is impossible to determine, but among untreated patients in the third pandemic it ranged from about 40% to 80%. In The Decameron by Giovanni Boccaccio (1313-75), for example, the ten fictional characters abandon plague-infested Florence in 1348 to travel into the surrounding countryside, where they entertain themselves by telling ten stories daily for ten days. Although the mechanisms were unclear, the disease seemed contagious, and a common response was to avoid the sick. Son père meurt alors qu'il n'a que deux ans. Plague has occurred in three pandemics, causing staggering mortality and social disruption. Hurrying to his laboratory with the specimens, he made slides and discovered masses of very small, thick bacilli with rounded ends. The Linh Son Phap Pagoda, in the village of SuÃ´i Cat, some 20 km from the Nha Trang Bay, contains a shrine to Yersin, whith his portrait, the object of a fervent cult. Stanford Libraries' official online search tool for books, media, journals, databases, government documents and more. When a rat corpse cools, the fleas seek another warm-bodied animal, preferentially another rat, but if none is available, humans suffice. Asked by the French government to help found a medical school in Hanoi, he acted as its director from 1902-1904. But plague is more the stuff of legend than dysenteryâ¦. Although Yersin clearly identified the plague bacillus, Kitasato had apparently discovered it six days earlier. His house in Nha Trang is now the Yersin Museum, and the epitaph on his tombstone describes him as a "Benefactor and humanist, venerated by the Vietnamese people". Yersin Photograph Collection. He developed vaccines and antisera for both men and animals and, as an agronomist, he introduced the Brazilian rubber tree and Peruvian cinchona tree (for quinine) into the country. While in Hong Kong, Yersin was helped in his research by an Italian priest of the PIME order named Bernardo Vigano. He inoculated agar, and the isolates, when injected into mice and rats, produced plague. Mars 2006.Câest lors de mon premier séjour prolongé au Vietnam en 2006 que jâai découvert lâexistence dâAlexandre Yersin dont le lycée français de Hanoi porte le nom. He proposed that there must be an intermediary between the rat and humans, suggesting the rat flea (Xenopsylla cheopsis) as the culprit. 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. While studying the disease in India, he found plague bacilli in the intestines of fleas from infected rats, but not in those from healthy ones. Paul-Louis Simond (1858- 1947), another Pasteur-trained microbiologist, noticed that people could safely handle rats that had died of the plague several hours earlier, but not when the animals had just expired. Alexandre Yersin, the diurnal South-western quadrant, consisting of the 7th, 8th and 9th houses, prevails in your chart: this sector brings about a thirst for communication and sometimes a need to take risks in your dealings with others. A common explanation in most culturesâ including Christian, Moslem, or Chineseâwas that it was Godâs vengeance for widespread human depravity. from left, back row (his name is Â© Institut Pasteur â MusÃ©e Pasteur. After his plague studies, he remained in Vietnam, except for brief trips abroad. 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. Hong Kong during the 1894 plague epidemic. left, front row. Pasteur was impressed with Yersinâs great scientific qualities, characterizing his habits of silent labor as almost ascetic. Further epidemics occurred intermittently, but frequently, in the succeeding years, until the second pandemic ended when plague disappeared from Europe in the 18th century. 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.
