Paul Ehrlich (1854- 1915) was a German scientist who worked in field of immunology, hematology and chemotherapy. In 1891, medical micro-organism had discovered by scientist, such as streptococci and staphylococci, these two organisms caused of disease and they began to examine them by microscopes. Paul Ehrlich took a part as a worker in Robert Koch’s bacteriology lab, he searched for a chemical that could stain specific microbe and produce more visible microbe under the microscope. Then, he also stated that the chemical which they searched could not only stain but also destroy the microbes but not damage the patient’s body. This chemical is what they called the “Magic Bullets”.
Introduction Biotechnology is the use of biological systems or organisms to create products or perform processes that are beneficial to mankind. Broadly, this entails any form of manipulation to biological organisms and systems. Even though lab related biotechnology expanded in the late twentieth century, following the discovery of Deoxyribonucleic Acid (DNA) in 1953, much older biotechnological techniques and processes had already existed. These include beer production, biological pest control and domestication of plants and animals; including selective crop farming and breeding of livestock. Following the exponential growth in the field of biotechnology many societal, ethical and legal issues have emerged.
The germ theory of disease, also called the pathogenic theory of medicine, is a theory that proposes that microorganisms are the cause of many diseases. Although highly controversial when first proposed, the germ theory was validated in the late 19th century and is now a fundamental part of modern medicine and clinical microbiology leading to such important innovations as antibiotics and hygienic practices. According to Louis Pasteur, germs or microbes cause disease and these germs invade the body from the outside through air, water or the food that we take in. The human blood is sterile and can only be infected by outside microbes; these germs are monomorphic, that is, they have only one form and can be identified by species. Thus, specific diseases are caused by specific germs.
4. The discovery of what causes a disease was made by Louis Pasteur. Pasteur developed the Germ Theory, this states that a microorganism called the “Germ” can cause dangerous diseases. He discovered the germ in a food conversion, the germ was infecting the food and beverages causing people to get
He liked to fish and Sketch people portraits. H e his contributions to medicine or the study of medicine, Fermentation Pasteur’s first contribution to medicine was the study of microbes. During the1850’s, a wine manufacturer approached Pasteur. His company produced alcohol from beet sugar using Fermentation. The process was not always successful since alcohol
Chytridiomycosis and Its Effect on North American Anurans Barclay Culp General Seminar, Bio301A 4/5/16 Abstract: Infectious diseases are an issue for many higher level organisms. One such disease is chytridiomycosis caused by the fungus Batrachochytridium dendrobatidis. This review paper seeks to introduce the reader to this organism by giving some necessary background information on the organism. In addition, the paper will discuss the symptoms of chytridiomycosis in both larval and adult anurans infected with the fungus. Anurans native to North America will be the primary focus on the animals.
Third Generation Cephalosporin Cephalosporins are antimicrobial drugs that were first discovered in 1945 by Giuseppe Brotzu. Brotzu was a University of Cagliari professor and a Sardinia government official who worked to eradicate malaria. It was found that cultures of fungi called Cephalosporium acremonium, which came from sewage water, could inhibit the growth of other bacteria. Since then, many cephalosporin drugs have been formulated, among them the third generation cephalosporin, which has a broader spectrum of activity. Part 1: What Is Cephalosporin?
HISTORY The development of dentistry during the 19th century in combination with the germ theory of disease had a direct effect on the practice of dentistry. Irrigation in 19th century Literature from this period mostly contained numerous empirically based recommendations for a variety of rinsing agents and medicaments, such as pulp extirpation under a pool of oil of eucalyptus and cloves was advocated, the rationale being that these oils would penetrate the canal as the nerve was removed. Arsenic was introduced by Shearjashub Spooner et al (1836)4 to destroy the nerves of the teeth without causing pain. However, some cases of fatal consequences were reported due to the use of Arsenic and daily dressing with thorough canal irrigation was
Tuberculosis infection can now be confirmed using a new urine test developed by a group of researchers. The new urine test uses a type of dye on tiny molecular cages that contain a sugar type that coats tuberculosis bacteria. The researchers reported that the test can be used to diagnose anyone at any stage of the disease. Tuberculosis is a respiratory disease caused by the bacteria Mycobacterium tuberculosis. The disease primarily infects the lungs but as it progress, the infection can spread to other parts of the body.
These microscopic organisms include bacteria and archaea. Population evolution in microbial life refers to the change that occurs in the microscopic organism populations over a SC160 Basic Biology Assignment 08 period of time. Evolution of microbial life is used in science and research for researching and studying diseases caused by the evolving microorganisms. This information is used by scientists to research and develop with medications to fight these diseases. Population evolution and microbial life are presented in the following examples.
