Discovering Louis Pasteur The Amazing Story of Vaccines and Pasteurization

raise your hand if you know this place this is LS pasture and the research institute is named after him so who was he let's get started with all of his dedication in do Western France in 1822 Lewis pastur was born into Catholic Family unlike many Geniuses worldwide young Lewis was just just an average student he loved drawing and fishing he used to wander the streets with paintbrush in hand however Lewis's father was dissatisfied when he saw his son focusing only on seemingly meaningless paintings he insisted that Lewis continued to pursue an academic path thanks to his father's pressure he continued to study and worked as an assistant for Professor Lauren this laid the foundation for his love of science and research at the age of 25 he earned his phad during this time he was researching spontaneous generation and conducted experiments that showed no contamination microorganisms could not spontaneously generate continuing on his research Journey he was assigned by the emperor to study the fermentation process of wine subsequently he discovered remarkable phenomenon among the spoiled wine bottles if they were heated to temperature of 55 -60° and then cooled down these bottles could be reused normally nice this experiment led him to groundbreaking conclusion bacteria destruction currently this technology is widely applied to various Foods especially milk the technology is named after him pasteurization in an experiment related to silkworms pastur concluded that the silk worm's illness was due to germs he isolated the infected worms in separate room and the result was that the disease was contained not spreading any further this marked the birth of The Germ Theory after perfecting the theory that germs diseases sought to address serious issue faced by farmers in the 18 7s an outbreak of disease in chickens known as foul chera pastur and his colleagues cultured the bacteria responsible for foul chera and injected them into experimental chickens they discovered that if they injected live bacteria into the chickens after first injecting them with dose of inactivated bacteria the chickens showed no signs of illness this laid the foundation for the creation of the first col vaccine it's twist germ Theory also affects the life of the trash can because trash in many places causes many germs trash bins were created to raise awareness of trash in one room minimizing bacterial growth as much as possible Lewis married Marie Lauren in 1849 the daughter of the University he was working at they had five children but three of them died of typhoid he was very miserable and at that time he was partially paralyzed due to stroke he revealed that only work makes him feel comforted and happy Lewis's research is of great significance to the livestock industry but it only stops at animals at the age of 50 he began researching rabies disease that causes humans to suffer in painful and terrible way he teamed up with colleagues believing that the disease causing agent resided in the brain and spinal cord not due to curses or any magical spells as some people believed he cultivated the disease in rabbits and other animals passing it down through multiple Generations the subsequent generations of the disease ween significantly and so the rabies vaccine was born he then tested this vaccine on dogs and the results were astounding these dogs completely recovered from the disease in 1885 he took ing step to test this vaccine on humans for the first time it was 14-year-old boy bitten by dog in more than 10 places he was extremely anxious losing sleep for many days fearing that any failure would weigh heavily on his conscience however miracle happened the boy recovered since then billions of doses of the rabies vaccine have been produced and used for the past 138 years counting from pastor's invention of the first first rabies vaccine 3 years after his successful rabies experiment the pasture Institute named after him was inaugurated the institute's goal was to research and test vaccines for various diseases The Institute was named after him as resounding Applause for his lifelong dedication to humanity to this day The pastour Institute has presence in over 100 countries worldwide and countless vaccines have originated from here let's give final round of applause for the outstanding contributions of this exceptional scientist see you in future videos honoring more scientists if you like our video please give us thumbs up and subscribe to our Channel thank you goodbye
