Explain why the work of Robert Koch was so Important? (7 Marks) Koch discovered and developed what Pasteur did not. Using Germ theory, he discovered the germ that caused Anthrax, a disease that affected animals as well as people. This was a phenomenal breakthrough as this was the first time that a specific germ had been identified, this then 100% proved Pasteur’s theory, which then left a wide door open for many more scientists to investigate and discover other specific bacterial germs that were damaging to the human body. The reason this makes Koch so important is because if he hadn’t investigated Anthrax using Pasteur’s theory, the germ theory may never have caught on leaving people to believe false theories for much longer.
In the short article “Why evolution should be taught in public schools” by Laura H. Kahn, author states that in order to understand true science knowledge children in schools should be taught evolution of plants, animals and humans. In the beginning of her passage she gives example of previous science case that had to go through many struggles before it was accepted and approved. “In the nineteenth century, the prevailing dogma was "spontaneous generation." It did nothing to prepare scientists and physicians to develop effective strategies against the infectious diseases that were killing untold numbers of people. Louis Pasteur, the French chemist who developed the rabies vaccine, was instrumental in disproving spontaneous generation and replacing it with the germ theory of disease.
Bioterrorism is more of a threat because it cannot be traced. Anyone in our country could be pain off to release a lethal contagious agent to the public, and the effects will be
His first experiments were on rats where he found large differences in the strength and length of the NMR signals given off by the cancerous and healthy tissues. This work solidified his ideas of the MR Body Scanner. With much criticism from other scientists, in 1971 Damadian filed for a patent for his idea of NMR for detecting cancer. Herman Carr created one dimensional MR images. Then scientist Paul Lauterbur developed a way to make MR images in two dimensional and three dimensional using gradients.
TOXIC SHOCK SYNDROME 3 Toxic Shock Syndrome was first discovered around twenty years ago. It was quickly linked to the use of super absorbent tampons which were consequently taken off the market. One theory states that the tampons were creating small cuts in the vagina which allowed the bacteria to sneak in. Another theory says that while using tampons the blood stays stagnant. This is a perfect breeding ground for the bacteria.
Microbiology in the News: Poop Pills Elaine Altman Breckinridge School of Nursing Microbiology Anu Gupta December 20, 2014 Microbiology in the News: Poop Pills Shawn Mulligan, 53, of Calgary, Canada, is among the first patients to test prototype poop pills to cure the recurrent intestinal infections caused by Clostridium difficile also known as C. diff. Even though the idea was distasteful when he thought about it, the results were quick and was life changing for him. Shawn was one of the first people suffering from a terrible gut infection caused by the germ C. diff, to get better using fecal transplants. The fecal transplants can be delivered through nose tubes, colonoscopies or enemas, but he was one of the first to have it transplanted through poop
Drug manufacturers test medications on animals after they have been injected with viruses and diseases to see if the medications work on the animals. There are many companies who use animal research to test their products; unfortunately these organizations do not look for alternatives besides animal testing. If these atrocious acts were committed outside laboratories, they would be felonies. But animals suffer and die every day in laboratories with little or no protection from cruelty. It is immoral to
It reminded Hippocrates of a crab because of its ability to dig in and take hold (Mukherjee , p. 47 ). Even more interesting was how scientists have been trying to cure cancer since the BC time period. When Mukherjee discusses the age of cancer, he refers to the ancient discoveries of Imhotep in 2625 BC. Mukherjee talks about the surprising
The participants were never told what disease they were suffering from or of its seriousness. They were informed that they were being treated for bad blood which was a lie. They were even pleased because participating in the study assured them of free medical care, free meals etc. The experiment was brought to the notice of the media in 1972. News anchor; Harry Reasoner described it as a test that “used human beings as laboratory animals in a long and inefficient study of how long it takes syphilis to kill someone.” Even as the Public Health Service was exposed, they remained impenitent and said that the black men volunteered themselves to be used as an experiment.
The Price of Beauty Is it worth killing animals for a mascara? Many companies to create a new mascara scientists test the chemicals on rabbits to see its reaction. The result is, hundreds of rabbits blind or dead due to the creation of ONE mascara. Alternatives have been created all over the world for animal testing on cosmetics, which are more accurate, since rabbits, dogs, cats, etc. don’t react the same way as us.
