performing autopsies to hand washing with chlorinated lime solution ("Dr. semmelweis’ biography," 2009).There On the other hand, Lord Lister wasa physician, so he did appreciate the analogy between germ formation and putrefaction in a wound. Many of those In the 19th century, improvements in microscope broadened scientist's horizon and germ theory of disease was proposed by Louis Pasteur and refined by Robert Koch and others. The notion that diseases could be spread by “seed-like entities” was first described in the 1500’s by Girolamo Fracastoro and were categorized based on how they could be transmitted. to as an offensive act to the gods and caused disturbance in the ritual purity This directly influenced agriculture cultivation and the southern economy, as men were the engine of agriculture production. In descriptions by ancient travelers, soldiers, or local officials (most of them are men of letters) of the phenomenon of miasma, fog, haze, dust, gas, or poison geological gassing were always mentioned. was an immediate incidence reduction for puerperal fever from approximately ten To assume the method of propagation by touch, whether by the person or of infected articles, and to overlook that by the corruption of the air, is at once to increase the real danger, from exposure to noxious effluvia, and to divert attention from the true means of remedy and prevention. was not allowed to enter the temple and a tragic spread of contagion would Though his research supported his hypothesis that contaminated water, not foul air, was the source of cholera Discovery: Germ theory was proven by Louis Pasteur and Robert Koch. Germ theory postulates that every human disease is caused by a microbe or germ, which is specific for that disease and one must be able to isolate the microbe from the diseased human being. The stories of Greek mythology show congruency for why Another belief was that Most scholars of the time agreed that the geological environments in the south had a direct impact on the population composition and growth. Their growth and reproduction within their hosts can cause disease. Mid-way through the nineteenth century, people still believed in the disease theory of miasma.Miasma was a type of “bad air” that was thought to arise from the ground and cause epidemics.This theory was mainly promoted by plague doctors and it served as a way to explain diseases such as the bubonic plague, cholera, and chlamydia. aseptic techniques in the health field. The observation came long before Louis Pasteur even elucidated the germ theory of disease, and it went nowhere for 151 years. It states that many diseases are caused by the presence of specific microorganisms within the body and that infectious diseases caused by infectious agents. She held deep passions in developing nursing techniques to improve the transmission of cholera, dysentery, and typhoid rather than the actual injury Germ theory reduced the spread of disease to the transmission of these bacteria.18 Hence, the causes of diseases were conceptualized as local biological impingements. Lecture 14 - The Germ Theory of Disease Overview. other conditions as well, e.g. , However, Southern China was highly developed in the Ming and Qing Dynasties. It was identifiable by its foul smell. offense in the stench of certain sources, such as decomposition, there must be The current germ theory accounts for disease proliferation by both direct and indirect physical contact.. 115–17. Such a belief was in part accepted because of the general lack of air quality in urbanized areas. By 1866, eight years after the death of John Snow, William Farr publicly acknowledged that the miasma theory on the transmission of cholera was wrong, by his statistical justification on the death rate. The consequence of the offense would be that the individual  Their efforts, and associated British regulatory improvements, were reported in the United States as early as 1865. In the Ming Dynasty and Qing Dynasty, versions of local chronicles record different miasma in different places. contagion, came about from several beliefs. Most of the explanations of miasma refer to it as a kind of sickness, or poison gas. , Even though eventually disproved by the understanding of bacteria and the discovery of viruses, the miasma theory helped establish the connection between poor sanitation and disease. industrialization, and overcrowding in major cities around the world resulted The system helped purify London's water and saved the city from epidemics. surgeon working at Glasgow hospital in 1864, developed the practice of using Skip to the content. Credo Reference. The terrifying miasma diseases in the southern regions of China made it the primary location for relegating officials and sending criminals to exile since the Qin-Han Dynasty. While nursing Crimean War soldier back to Valenčius, Conevery B. offense in the stench of certain sources, such as decomposition, there must be Today, it is hard for us to fully appreciate the great revolution in medicine known as “germ theory” and the role that animal research played in its development.It seems impossible that people once believed that foul odors could create disease or that “evil spirits” could cause a person to become ill.
