The statistic for the Pennsylvania Hospital was 24%; Massachusetts General, 26%. Microorganisms are said to have been first directly observed in the 1670s by Anton van Leeuwenhoek, an early pioneer in microbiology, considered "the Father of Microbiology". He found out that germs were everywhere. He attended Quaker schools, where, among other things, he learned to speak fluent French and German (which were two of the major medical languages of that time). Later, researchers discovered that this public well had been dug only three feet from an old cesspit, which had begun to leak fecal bacteria. The Louis Pasteur germ theory came into being when the French chemist showed processes such as putrefaction and fermentation … LISTER'S RESEARCHES. Both a biography of Joseph Lister and an overview of nineteenth century understanding of germ theory and antiseptics. Bit by bit, this missionary zeal began to have an effect in England, Ireland, and Scotland. One of his books written in 1646 contains a chapter in Latin, which reads in translation "Concerning the wonderful structure of things in nature, investigated by Microscope", stating "who would believe that vinegar and milk abound with an innumerable multitude of worms." To accept his proposal would have meant accepting the fecal-oral method transmission of disease, which they dismissed.[31]. [20], A basic form of contagion theory dates back to medicine in the medieval Islamic world, where it was proposed by Persian physician Ibn Sina (known as Avicenna in Europe) in The Canon of Medicine (1025), which later became the most authoritative medical textbook in Europe up until the 16th century. Joseph Lister and the use of antiseptics Until the acceptance of germ theory in the 1860s, surgeons did not take any precautions to protect open wounds from infection. It is regarded as one of the founding events of the science of epidemiology. Few major advancements in the field of surgery can be considered as important as the work of Dr. Lister—the application of germ cell theory to the surgical arena. A Brief Summary of Louis Pasteur’s Germ Theory of Disease. Even though the germ theory of disease pioneered by Girolamo Fracastoro had not yet achieved full development or widespread currency, Snow demonstrated a clear understanding of germ theory in his writings. Its opening was originally under a nearby house, which had been rebuilt farther away after a fire. Lister’s ability to demonstrate his theory through bacteria cultures viewed through a microscope was unconvincing to other doctors. Basic forms of germ theory were proposed in the late Middle Ages by physicians including Ibn Sina in 1025,[2] Ibn Khatima and Ibn al-Khatib in the 14th century,[3] Girolamo Fracastoro in 1546, and expanded upon by Marcus von Plenciz in 1762. When finally accepted, this germ-theory stuff revolutionized not only surgery, but all of medicine. This action has been commonly credited as ending the outbreak, but Snow observed that the epidemic may have already been in rapid decline.[29]. Investigating further, Semmelweis made the connection between puerperal fever and examinations of delivering women by doctors, and further realized that these physicians had usually come directly from autopsies. He noted the presence of "little worms" or "animalcules" in the blood and concluded that the disease was caused by microorganisms. In summary, a body of evidence that satisfies Koch's postulates is sufficient but not necessary to establish causation. He exposed freshly boiled broth to air in vessels that contained a filter to stop all particles passing through to the growth medium, and even with no filter at all, with air being admitted via a long tortuous tube that would not pass dust particles. The theory posited that diseases were the product of environmental factors such as contaminated water, foul air, and poor hygienic conditions. I hope everybody enjoyed and learned from this little lesson. The figures in Paris were worse—60% of patients with amputations died; in Zurich, 46%; in Glasgow, 34%. West Ham, Newham, Greater London, England, United Kingdom Joseph Lister is the surgeon who introduced new principles of cleanliness which transformed surgical practice in the late 1800s. Often disturbing—particularly some of the descriptions of surgery—but fascinating. 110-17. Kircher defined the invisible organisms found in decaying bodies, meat, milk, and secretions as "worms". Snow's 1849 recommendation that water be "filtered and boiled before it is used" is one of the first practical applications of germ theory in the area of public health and is the antecedent to the modern boil-water advisory. should treat patients with those types of problems. The English, Joseph Lister, German Robert Koch and French chemist Louis Pasteur are credited with the development of the germ theory of disease. Snow later used a dot map to illustrate the cluster of cholera cases around the pump. [9], In Antiquity, the Greek historian Thucydides (c. 460 – c. 400 BC) was the first person to write, in his account of the plague of Athens, that diseases could spread from an infected person to others. The most powerful evidence in support of Lister came in the form of a book Koch wrote 2 years later, in which he linked six different kinds of surgical infection to six specific bacteria. In 1762, the Austrian physician Marcus Antonius von Plenciz (1705–1786) published a book titled Opera medico-physica. The cultured microorganism should cause disease when introduced into a healthy organism. In England, no one knew that much about microscopy. “An Address on the Antiseptic System of Treatment in Surgery” was a description of a new way of doing operations that he first presented in Glasgow, Scotland, where he … Recent stuff #29 Yelling, cursing are less likely to break out in operating rooms when…. ... Joseph lister. Germ Theory and Its Applications to Medicine & On the Antiseptic Principle of [sic.in] the Practice of Surgery: Louis Pasteur and Joseph Lister. His father developed better microscopes so he would have known about science which would have helped his career In surgery/doctors. This led Lister to recognize the role of bacteria entering wounds from the air; and, therefore, he developed the antiseptic treatment of wounds (with carbolic aci… A surgeon was not required to wash his hands before seeing a patient; in the absence of any theory of bacterial infection, such practices were not considered necessar… This work was later extended by Robert Koch in the 1880s. His studies with the microscope led him to the belief, which he was possibly the first to hold, that disease and putrefaction (decay) were caused by the presence of invisible living bodies. He graduated from the University of London in 1852 and began a surgical career in Edinburgh. [12][13], The Roman statesman Marcus Terentius Varro (116–27 BC) wrote, in his Rerum rusticarum libri III (Three Books on Agriculture, 36 BC): "Precautions must also be taken in the neighborhood of swamps […] because there are bred certain minute creatures which cannot be seen by the eyes, which float in the air and enter the body through the mouth and nose and there cause serious diseases. The microorganism must be found in abundance in all organisms suffering from the disease, but should not be found in healthy organisms. Using carbolic acid – only 6 of 40 patients (15%) had died. Noninfection may be due to such factors as general health and proper immune functioning; acquired immunity from previous exposure or vaccination; or genetic immunity, as with the resistance to malaria conferred by possessing at least one sickle cell allele. It is considered as the cornerstone of modern medicine and clinical microbiology. Instead of merely striding into an operating room, amputating a leg within a minute or two, and then, maybe, washing their hands, surgeons were now being asked/told to 1) change their clothes, 2) spray their hands and instruments with carbolic acid and 3) spray the wound repeatedly, and 4) and finally apply a complicated dressing and more. Find out about the life of Joseph Lister. Joseph Lister the Father of Modern Antisepsis (1860s) Despite previous discoveries to the contrary, a prevailing belief persisted that wound infection was due to tissue exposed to stinking "miasma" in air, and it was still considered unnecessary for a surgeon to wash his hands before seeing a patient. [4][N 1] A transitional period began in the late 1850s with the work of Louis Pasteur. In 1861, Lister observed that 45 to 50 percent of amputation patients died from sepsis. This greatly revolutionized the approach towards the study of infectious diseases as well as the treatment methods. Can J Surg. By talking to local residents, he identified the source of the outbreak as the public water pump on Broad Street (now Broadwick Street). Lister was determined to spread his doctrine. no infection! This is a part of the why and the where the term ‘internist’ came from, in that if any surgeon tried to do anything to the abdomen and chest, their/that patient would most assuredly die and so only non-surgeons (so-called internists) should treat patients with those types of problems. Despite this evidence, he and his theories were rejected by most of the contemporary medical establishment. Many surgeons simply expected germs to live in wounds; others claimed that germs (the bacteria) appeared in wounds only after the infection had started. Although the development of the germ theory of disease in the latter half of the nineteenth century marks a major revolution in medical science, comparable to the discoveries of Galileo in astronomy or Darwin in biology, it cannot be reduced to the heroic efforts of a single researcher or group of researchers. The word "bacteria" didn't exist yet, so he called these microscopic living organisms "animalcules", meaning "little animals". Lister knew that the injury would become 1) infected and that the only cure would be 2) amputation, an operation with a 3) mortality rate of about 45%. Print. Lister looked for a subject with a wound he could spray with this carbolic acid. For the morbid matter of cholera having the property of reproducing its own kind, must necessarily have some sort of structure, most likely that of a cell. And so, with the except for laudable pus, the appearance of any other kind of infection meant a very likely death; >45% mortality with this type of pus/infection. [8], The Mosaic Law contains the earliest sentiment of contagion in the spread of disease, standing in contrast with classical medical tradition and the Hippocratic writings. certain diseases are caused by the invasion of the body by microorganisms, organisms too small to be seen except through a microscope. 1. It was not possible for a surgeon to into the abdomen nor the chest because the infection and death rates were extremely high (bordering on 100%). One exception was Joseph Lister, a British surgeon who had read Pasteur’s reports to the Academie des Sciences, and consequently sought to reduce the morbidity and mortality in his practice. 5 Apr - short biography, births, deaths and events on date of Lister's birth. Lecture 14 - The Germ Theory of Disease Overview. However, Koch abandoned the universalist requirement of the first postulate altogether when he discovered asymptomatic carriers of cholera[35] and, later, of typhoid fever. Pasteur first looked at normal wine under his microscope and saw yeast, And when he looked at the putrefied wine, he also saw rod-shaped structures. Joseph Lister read Pasteur’s work on fermentation and questioned whether micro-organisms might cause infections in wounds in the same way that it ruined wine and decided to experiment with using one of Pasteur’s proposed techniques, that of exposing the wound to chemicals.

In the 1870s, Joseph Lister was instrumental in developing practical applications of the germ theory of disease with respect to sanitation in medical settings and aseptic surgical techniques—partly through the use of carbolic acid (phenol) as an antiseptic. These postulates grew out of his seminal work with anthrax using purified cultures of the pathogen that had been isolated from diseased animals. More meticulous surgery was then being performed, the importance of laboratory work was becoming more evident, and striking information from France and Germany began to emerge: In 1876, the German Robert Koch was the first to identify a specific bacterium as the cause of a disease—anthrax. The microorganism must be isolated from a diseased organism and grown in pure. - … The third postulate specifies "should", not "must", because as Koch himself proved in regard to both tuberculosis and cholera,[34] not all organisms exposed to an infectious agent will acquire the infection. Dr. Joseph Lister Joseph Lister, a surgeon, took germ theory a step further and developed a means of sterilizing wounds and medical instruments using carbolic acid. Ultimately, Lister published a comparison of amputations done with and without carbolic acid. This, of course, made the surgery a horrible experience for the patient. [15] In his On the Different Types of Fever (c. AD 175), Galen speculated that plagues were spread by "certain seeds of plague", which were present in the air. Italian physician Francesco Redi provided early evidence against spontaneous generation. Asserting that puerperal fever was a contagious disease and that matter from autopsies were implicated in its development, Semmelweis made doctors wash their hands with chlorinated lime water before examining pregnant women.
