World Rabies Day is an international awareness campaign coordinated by the Global Alliance for Rabies Control , a non-profit organization with headquarters in the United States. It is a United Nations Observance and has been endorsed by international human and veterinary health organizations such as the World Health Organization , the Pan American Health Organization , the World Organisation for Animal Health and the US Centers for Disease Control and Prevention .
85-461: World Rabies Day takes place each year on September 28, the anniversary of the death of Louis Pasteur who, with the collaboration of his colleagues, developed the first efficacious rabies vaccine . World Rabies Day aims to raise awareness about the impact of rabies on humans and animals, provide information and advice on how to prevent the disease in at-risk communities, and support advocacy for increased efforts in rabies control. Rabies remains
170-423: A chemist , beginning at the École Normale Supérieure , and continuing at Strasbourg and Lille, he examined the chemical, optical and crystallographic properties of a group of compounds known as tartrates . He resolved a problem concerning the nature of tartaric acid in 1848. A solution of this compound derived from living things rotated the plane of polarization of light passing through it. The problem

Each Sectional Committee covers different specialist areas including: New Fellows are admitted to the Society at a formal admissions day ceremony held annually in July, when they sign the Charter Book and the Obligation which reads: "We who have hereunto subscribed, do hereby promise, that we will endeavour to promote
425-645: A bank of awareness resources through the website of the Global Alliance for Rabies Control for use in local educational initiatives. As rabies is a disease that crosses borders, especially in wild animal populations, the campaign encourages the transnational collaboration of rabies control and prevention organizations. It also promotes a One Health approach to rabies prevention, part of a worldwide strategy for expanding interdisciplinary collaborations and communications in all aspects of health care for humans and animal health. The WRD logo (pictured above) represents

On another occasion he threatened to expel any student caught smoking, and 73 of the 80 students in the school resigned. In 1863, he was appointed professor of geology, physics, and chemistry at the École nationale supérieure des Beaux-Arts , a position he held until his resignation in 1867. In 1867, he became
595-623: A new disease that was decimating silkworm farms from the south of France and Europe, the pébrine , characterized on a macroscopic scale by black spots and on a microscopic scale by the " Cornalia corpuscles". Pasteur accepted and made five long stays in Alès , between 7 June 1865 and 1869. Arriving in Alès, Pasteur familiarized himself with pébrine and also with another disease of the silkworm, known earlier than pebrine: flacherie or dead-flat disease. Contrary, for example, to Quatrefages , who coined
680-406: A note published on 27 August 1866 by Balbiani , which Pasteur at first seemed to welcome favourably had no effect, at least immediately. "Pasteur is mistaken. He would only change his mind in the course of 1867". At a time where Pasteur had not yet understood the cause of the pébrine, he propagated an effective process to stop infections: a sample of chrysalises was chosen, they were crushed and

He was the director of the Pasteur Institute , established in 1887, until his death, and his body was interred in a vault beneath the institute. Although Pasteur made groundbreaking experiments, his reputation became associated with various controversies. Historical reassessment of his notebook revealed that he practiced deception to overcome his rivals. Louis Pasteur
935-487: A significant health problem in many countries of the world. Over 99% of all human deaths caused by rabid dog bites happen in the developing world, with 95% of deaths occurring in Africa and Asia. With the exception of Antarctica, people and animals on every continent are at risk of contracting rabies. One major problem with rabies prevention is a lack of basic life-saving knowledge among people at risk. Organizations working on

In the years following the review, World Rabies Day has also been used by governments and international agencies as a day on which to announce policies, plans and progress on rabies elimination. For example, In 2013, the Food and Agricultural Organization of
1105-406: A vaccine for anthrax , which affected cattle . In 1877, Pasteur had earlier directed his laboratory to culture the bacteria from the blood of infected animals, following thediscovery of the bacterium by Robert Koch. When animals were infected with the bacteria, anthrax occurred, proving that the bacteria was the cause of the disease. Many cattle were dying of anthrax in "cursed fields". Pasteur
1190-434: A vaccine for all infectious diseases that have repeatedly afflicted humanity, and are a major burden on agriculture and breeding of domestic animals. In fact, Pasteur's vaccine against chicken cholera did not consistently produce immunity, and has subsequently been proven to be ineffective. Following the results with chicken cholera, Pasteur eventually utilized the immunization method developed for chicken cholera to create

An indicative allocation of 18 Fellowships can be allocated to candidates from Physical Sciences and Biological Sciences; and up to 10 from Applied Sciences, Human Sciences and Joint Physical and Biological Sciences. A further maximum of six can be 'Honorary', 'General' or 'Royal' Fellows. Nominations for Fellowship are peer reviewed by Sectional Committees, each with at least 12 members and
1445-421: Is nominated by two Fellows of the Royal Society (a proposer and a seconder), who sign a certificate of proposal. Previously, nominations required at least five fellows to support each nomination by the proposer, which was criticised for supposedly establishing an old boy network and elitist gentlemen's club . The certificate of election (see for example ) includes a statement of the principal grounds on which
1530-633: Is regarded as one of the founders of modern bacteriology and has been honored as the "father of bacteriology" and the "father of microbiology " (together with Robert Koch ; the latter epithet also attributed to Antonie van Leeuwenhoek ). Pasteur was responsible for disproving the doctrine of spontaneous generation . Under the auspices of the French Academy of Sciences , his experiment demonstrated that in sterilized and sealed flasks, nothing ever developed; conversely, in sterilized but open flasks, microorganisms could grow. For this experiment,
1615-469: Is the crucial point of my subject. I ask the Academy not to criticize, for the time being, the confidence of my proceedings that permit me to determine the microbe's attenuation, in order to save the independence of my studies and to better assure their progress... [In conclusion] I would like to point out to the Academy two main consequences to the facts presented: the hope to culture all microbes and to find
1700-476: The baccalauréat scientifique (general science) degree from Dijon , where he earned his Bachelor of Science in Mathematics degree (Bachelier ès Sciences Mathématiques) in 1842, but with a mediocre grade in chemistry. Later in 1842, Pasteur took the entrance test for the École Normale Supérieure . During the test, he had to fight fatigue and only felt comfortable with physics and mathematics. He passed
1785-559: The licencié ès sciences degree. In 1846, he was appointed professor of physics at the Collège de Tournon (now called Lycée Gabriel-Faure ) in Ardèche . But the chemist Antoine Jérôme Balard wanted him back at the École Normale Supérieure as a graduate laboratory assistant ( agrégé préparateur ). He joined Balard and simultaneously started his research in crystallography and in 1847, he submitted his two theses, one in chemistry and

#17327938268851870-512: The Pasteur effect . Pasteur's research also showed that the growth of micro-organisms was responsible for spoiling beverages, such as beer, wine and milk. With this established, he invented a process in which liquids such as milk were heated to a temperature between 60 and 100 °C. This killed most bacteria and moulds already present within them. Pasteur and Claude Bernard completed tests on blood and urine on 20 April 1862. Pasteur patented
1955-426: The post-nominal letters FRS . Every year, fellows elect up to ten new foreign members. Like fellows, foreign members are elected for life through peer review on the basis of excellence in science. As of 2016 , there are around 165 foreign members, who are entitled to use the post-nominal ForMemRS . Honorary Fellowship is an honorary academic title awarded to candidates who have given distinguished service to
2040-413: The 17th and 18th centuries, respectively. Spallanzani's experiments in 1765 suggested that air contaminated broths with bacteria. In the 1860s, Pasteur repeated Spallanzani's experiments, but Pouchet reported a different result using a different broth. Pasteur performed several experiments to disprove spontaneous generation. He placed boiled liquid in a flask and let hot air enter the flask. Then he closed
2125-646: The Blueprint for Rabies Prevention. The Food and Agricultural Organization of the UN considers that World Rabies Day plays an important role in advocating the prevention and control of rabies among policy makers, especially in countries where rabies is still neglected. Events held to mark World Rabies Day range from symposia on current rabies control methods and public events for raising awareness about good prevention practice, to sponsored walks, runs or bike rides, to free or externally subsidized vaccination clinics for dogs. In

In 1839, he entered the Collège Royal at Besançon to study philosophy and earned his Bachelor of Letters degree in 1840. He was appointed a tutor at the Besançon college while continuing a degree science course with special mathematics. He failed his first examination in 1841. He managed to pass
2295-520: The Cévennes. In 1878, at the Congrès international séricicole , Pasteur admitted that "if pébrine is overcome, flacherie still exerts its ravages". He attributed the persistence of flacherie to the fact that the farmers had not followed his advice. In 1884, Balbiani , who disregarded the theoretical value of Pasteur's work on silkworm diseases, acknowledged that his practical process had remedied
2380-603: The Dijon Lycée in 1848, he became professor of chemistry at the University of Strasbourg , where he met and courted Marie Laurent , daughter of the university's rector in 1849. They were married on 29 May 1849, and together had five children, only two of whom survived to adulthood; the other three died of typhoid . Pasteur was appointed professor of chemistry at the University of Strasbourg in 1848, and became

He concluded that: Never will the doctrine of spontaneous generation recover from the mortal blow of this simple experiment. There is no known circumstance in which it can be confirmed that microscopic beings came into the world without germs, without parents similar to themselves. In 1865, Jean-Baptiste Dumas , chemist, senator and former Minister of Agriculture and Commerce, asked Pasteur to study
2550-570: The French Academy of Sciences a report from Henry Toussaint , a veterinary surgeon , who was not a member of the academy. Toussaint had developed anthrax vaccine by killing the bacilli by heating at 55 °C for 10 minutes. He tested his vaccine on eight dogs and 11 sheep, half of which died after inoculation. It was not a great success. Upon hearing the news, Pasteur immediately wrote to the academy that he could not believe that dead vaccine would work and that Toussaint's claim "overturns all
2635-431: The French Academy of Sciences on 13 June concludes: [By] looking at everything from the scientific point of view, the development of a vaccination against anthrax constitutes significant progress beyond the first vaccine developed by Jenner, since the latter had never been obtained experimentally. Pasteur did not directly disclose how he prepared the vaccines used at Pouilly-le-Fort. Although his report indicated it as

Pasteur's assistants, Roux and Chamberland, who were assigned the task of conducting the trial, were concerned about the unreliability of the attenuated vaccine, and therefore Chamberland secretly prepared an alternative vaccine using chemical inactivation. Without divulging their method of preparing
3145-552: The UN, the World Health Organization and the World Organisation for Animal Health first called for the global elimination of canine-mediated rabies in a joint statement released on World Rabies Day. It has been included in the Association of Southeast Asian Nations Rabies Elimination Strategy. At the first Pan-African Rabies Control Network meeting in 2015, the 33 African countries represented there recommended consideration of World Rabies Day as an opportunity for rabies advocacy. In
3230-400: The academy awarded him the Alhumbert Prize carrying 2,500 francs in 1862. Pasteur is also regarded as one of the fathers of germ theory of diseases , which was a minor medical concept at the time. His many experiments showed that diseases could be prevented by killing or stopping germs, thereby directly supporting the germ theory and its application in clinical medicine. He is best known to
3315-605: The bacteria samples (later called Pasteurella multocida after him) from Henry Toussaint . Being unnable to conduct the experiments himself due to a stroke in 1868, Pasteur relied heavily on his assistants Emile Roux and Charles Chamberland. The work with chicken cholera was initiated in 1877, and by the next year, Roux was able to maintain a stable culture using broths. As documented later by Pasteur in his notebook in March of 1880, in October of 1879, being delayed in returning to
3400-407: The bacteria were weakened by contact with oxygen. He explained that bacteria kept in sealed containers never lost their virulence, and only those exposed to air in culture media could be used as vaccine. Pasteur introduced the term "attenuation" for this weakening of virulence as he presented before the academy, saying: We can diminish the microbe's virulence by changing the mode of culturing. This

In February 1854, so that he would have time to carry out work that could earn him the title of correspondent of the Institute, he got three months' paid leave with the help of a medical certificate of convenience. He extended the leave until 1 August, the date of the start of the exams. "I tell the Minister that I will go and do the examinations so as not to increase

In 1867, the École Normale's laboratory of physiological chemistry was created at Pasteur's request, and he was the laboratory's director from 1867 to 1888. In Paris, he established the Pasteur Institute in 1887, in which he was its director for the rest of his life. In Pasteur's early work as

In the early 19th century, Agostino Bassi had shown that muscardine was caused by a fungus that infected silkworms. Since 1853, two diseases called pébrine and flacherie had been infecting great numbers of silkworms in southern France, and by 1865 they were causing huge losses to farmers. In 1865, Pasteur went to Alès and worked for five years until 1870. Silkworms with pébrine were covered in corpuscles. In

In this same year 1854, he was named dean of the new faculty of sciences at University of Lille , where he began his studies on fermentation. It was on this occasion that Pasteur uttered his oft-quoted remark: " dans les champs de l'observation, le hasard ne favorise que les esprits préparés " ("In

In 1857, he moved to Paris as the director of scientific studies at the École Normale Supérieure where he took control from 1858 to 1867 and introduced a series of reforms to improve the standard of scientific work. The examinations became more rigid, which led to better results, greater competition, and increased prestige. Many of his decrees, however, were rigid and authoritarian, leading to two serious student revolts. During "the bean revolt" he decreed that
4335-477: The first explanation of isomerism . Some historians consider Pasteur's work in this area to be his "most profound and most original contributions to science", and his "greatest scientific discovery." Pasteur was motivated to investigate fermentation while working at Lille. In 1856 a local wine manufacturer, M. Bigot, whose son was one of Pasteur's students, sought for his advice on the problems of making beetroot alcohol and souring. Pasteur began his research in

He went back to the Parisian boarding school to prepare for the test. He also attended classes at the Lycée Saint-Louis and lectures of Jean-Baptiste Dumas at the Sorbonne . In 1843, he passed the test with a high ranking and entered the École Normale Supérieure . In 1845 he received

Louis Pasteur Louis Pasteur ForMemRS ( / ˈ l uː i p æ ˈ s t ɜːr / , French: [lwi pastœʁ] ; 27 December 1822 – 28 September 1895) was a French chemist , pharmacist , and microbiologist renowned for his discoveries of
4590-399: The first three years, Pasteur thought that the corpuscles were a symptom of the disease. In 1870, he concluded that the corpuscles were the cause of pébrine (it is now known that the cause is a microsporidian ). Pasteur also showed that the disease was hereditary. Pasteur developed a system to prevent pébrine: after the female moths laid their eggs, the moths were turned into a pulp. The pulp

The number of flasks in which organisms grew was lower at higher altitudes, showing that air at high altitudes contained less dust and fewer organisms. Pasteur also used swan neck flasks containing a fermentable liquid. Air

Pasteur thought that this type of killed vaccine should not work because he believed that attenuated bacteria used up nutrients that the bacteria needed to grow. He thought oxidizing bacteria when sitting in culture broth for prolonged periods made them less virulent. However, Pasteur's laboratory found that anthrax bacillus

It was in letters of 30 April and 21 May 1867 to Dumas that he first made the distinction between pébrine and flacherie. He made another mistake: he began by denying the "parasitic" (microbial) nature of pébrine, which several scholars (notably Antoine Béchamp ) considered well established. Even

Despite Pasteur's success against pébrine, French sericulture had not been saved from damage. (See fr:Sériciculture in the French Misplaced Pages.) Pasteur's first work on vaccine development was on chicken cholera . He received
6120-404: The same two chickens. As was also noted by Pasteur in his notebook in March of 1880, and contrary to some accounts, this time the chickens died. Thus, although the attenuated bacteria did not provide immunity, these experiments provided important clues as to how bacteria could be artificially attenuated in the laboratory. As a result, upon Pasteur’s return to the laboratory, the focus of the research
6205-459: The skin of grapes was the natural source of yeasts, and that sterilized grapes and grape juice never fermented. He drew grape juice from under the skin with sterilized needles, and also covered grapes with sterilized cloth. Both experiments could not produce wine in sterilized containers. His findings and ideas were against the prevailing notion of spontaneous generation . He received a particularly stern criticism from Félix Archimède Pouchet , who
6290-476: The topic by repeating and confirming works of Theodor Schwann , who demonstrated a decade earlier that yeast were alive. According to his son-in-law, René Vallery-Radot, in August 1857 Pasteur sent a paper about lactic acid fermentation to the Société des Sciences de Lille, but the paper was read three months later. A memoire was subsequently published on 30 November 1857. In the memoir, he developed his ideas stating that: "I intend to establish that, just as there
6375-420: The vaccine to anyone but Pasteur, Roux and Chamberland performed the public experiment on May at Pouilly-le-Fort. 58 sheep, 2 goats and 10 cattle were used, half of which were given the vaccine on 5 and 17 May; while the other half was untreated. On 31 May, Roux and Chamberland next injected the animals with the fresh virulent culture of anthrax bacillus. The official result was observed and analyzed on 2 June in
6460-412: Was allowed to enter the flask via a long curving tube that made dust particles stick to it. Nothing grew in the broths unless the flasks were tilted, making the liquid touch the contaminated walls of the neck. This showed that the living organisms that grew in such broths came from outside, on dust, rather than spontaneously generating within the liquid or from the action of pure air. These were some of
6545-613: Was born on 27 December 1822, in Dole, Jura , France, to a Catholic family of a poor tanner . He was the third child of Jean-Joseph Pasteur and Jeanne-Etiennette Roqui. The family moved to Marnoz in 1826 and then to Arbois in 1827. Pasteur entered primary school in 1831. He was dyslexic and dysgraphic . He was an average student in his early years, and not particularly academic, as his interests were fishing and sketching . He drew many pastels and portraits of his parents, friends and neighbors. Pasteur attended secondary school at
6630-456: Was caused by decomposition. Pasteur demonstrated that this theory was incorrect, and that yeast was responsible for fermentation to produce alcohol from sugar. He also demonstrated that, when a different microorganism contaminated the wine, lactic acid was produced, making the wine sour. In 1861, Pasteur observed that less sugar fermented per part of yeast when the yeast was exposed to air. The lower rate of fermentation aerobically became known as
6715-477: Was directed at creating a vaccine through attenuation. In February of 1880, Pasteur presented his results to the French Academy of Sciences as " Sur les maladies virulentes et en particulier sur la maladie appelée vulgairement choléra des poules (On virulent diseases, and in particular on the disease commonly called chicken cholera)" and published it in the academy's journal ( Comptes-Rendus hebdomadaires des séances de l'Académie des Sciences ). He attributed that
6800-644: Was director of the Rouen Museum of Natural History . To settle the debate between the eminent scientists, the French Academy of Sciences offered the Alhumbert Prize carrying 2,500 francs to whoever could experimentally demonstrate for or against the doctrine. Pouchet stated that air everywhere could cause spontaneous generation of living organisms in liquids. In the late 1850s, he performed experiments and claimed that they were evidence of spontaneous generation. Francesco Redi and Lazzaro Spallanzani had provided some evidence against spontaneous generation in
6885-519: Was examined with a microscope, and if corpuscles were observed, the eggs were destroyed. Pasteur concluded that bacteria caused flacherie. The primary cause is currently thought to be viruses. The spread of flacherie could be accidental or hereditary. Hygiene could be used to prevent accidental flacherie. Moths whose digestive cavities did not contain the microorganisms causing flacherie were used to lay eggs, preventing hereditary flacherie. Following his fermentation experiments, Pasteur demonstrated that
6970-421: Was not a Royal Fellow, but provided her patronage to the society, as all reigning British monarchs have done since Charles II of England . Prince Philip, Duke of Edinburgh (1951) was elected under statute 12, not as a Royal Fellow. The election of new fellows is announced annually in May, after their nomination and a period of peer-reviewed selection. Each candidate for Fellowship or Foreign Membership
7055-467: Was not easily weakened by culturing in air as it formed spores – unlike chicken cholera bacillus. In early 1881, his laboratory discovered that growing anthrax bacilli at about 42 °C made them unable to produce spores, and he described this method in a speech to the French Academy of Sciences on 28 February. On 21 March, despite inconsistent results, he announced successful vaccination of sheep. To this news, veterinarian Hippolyte Rossignol proposed that
7140-421: Was that tartaric acid derived by chemical synthesis had no such effect, even though its chemical reactions were identical and its elemental composition was the same. Pasteur noticed that crystals of tartrates had small faces. Then he observed that, in racemic mixtures of tartrates, half of the crystals were right-handed and half were left-handed. In solution, the right-handed compound was dextrorotatory , and
7225-417: Was told that sheep that died from anthrax were buried in the field. Pasteur thought that earthworms might have brought the bacteria to the surface. He found anthrax bacteria in earthworms' excrement, showing that he was correct. He told the farmers not to bury dead animals in the fields. Pasteur's interest in creating a vaccine for anthrax was greatly stimulated when on 12 July 1880, Henri Bouley read before
