Antibiotics

contain a DNA strand. Bacteria are identified into five groups: cocci, bacilli, spirilla, vibrios, and spirochaetes, which are classified by shape. Antibiotics are created to fight off bacteria related illnesses, some bacteria can evolve to become antibiotic resistant. Through a complex process, some bacteria that survive the antibiotic, will form newly antibiotic resistance bacteria. E. coli (Escherichia coli 0157:H7) is a type of bacteria that can be harmful to humans, which causes severe…

Chemotherapy Chemotherapy sometimes involves the use of antibiotic drugs since it is basically defined as the use of chemicals or medication to treat diseases. However, this term is used to specifically refer to the medical processes that are geared toward the destruction of cancer cells. In some cases, the process involves using antibiotics and other medications to treat certain infections or illnesses that may arise as a result of the clinical processes toward destruction of cancer cells.…

prescribe antibiotics. However, without the discovery of penicillin, strep would still be a very dangerous infection. Penicillin is an antibiotic from the mold penicillium notam, and works by indirectly breaking down a bacteria’s cell walls. The drug prevents a protein from repairing holes in the wall, and by osmosis, water rushes in and the bacteria explodes. This quickly destroys bacterial infections, which is why it is so popularly used and among one of the most well known…

There were several types of antibiotics that have a structure similar to that of a crown ether and one antibiotic that has a structure similar to crown ether would be gramicidin. Gramicidin works against gram-positive bacteria but it doesn’t work against gram-positive bacilli. It also works against select gram-negative organisms. In the year 1939, René Dubos discovered the gramicidin antibiotic.1 Gramicidin contains a mixture of three antibiotic compounds, gramicidins A, B and C and with its…

his discovery of the penicillin. Fleming was one the most important scientists in the medical world, whose actions changed the world. Through years of work, Alexander Fleming made a major contribution through his discovery of the world’s first antibiotic, Penicillin. Sir Alexander…

doses that are too small allow for resistant strains of bacteria (Ho). In today’s society, the overuse of antibiotics, including penicillin, has allowed a multitude of bacteria to adapt and become resistant to medications ("Anti-Microbial Stewardship"). Antibiotic resistance has lead the development of antibiotic stewardship programs in the United States and a push to develop new antibiotics, because only two new types have been developed since 1962 ("Anti-Microbial Stewardship;"…

Before penicillin was founded, there was no real cure for infections such as pneumonia. People who even got cut or scratched would sometimes have to go to the hospital because they would get blood poisoning. It had long been discovered that antibiotics were compounds of bacteria and fungi, but it was not until the year of 1928 that penicillin was discovered. In September of 1928, Alexander Fleming was sorting through some petri dishes that contained Staphylococcus and other bacteria. He found…

back his dishes were covered in mold and wanted to examine them. The mold on the dishes had a lot of bacteria but there was ring around the mold which was spore that was bacteria free known as penicillin. From there penicillin grew to be used as a antibiotic and saved many lives.…

due to the close proximity of the gunfights and some lives were lost due to the lack of appropriate treatments to the soldiers. The doctors operated on soldiers in very unsanitary conditions, used non-sterilized tools, and did not have today’s antibiotics. John Buford was shot, the bullet had penetrated two inches into his left arm, the skin around the wound was peeled back like a banana covered with blood. As the author says on “He had been hit once in the left arm and the bleeding had…

discovered antibiotics. Before this discovery Greeks and Indians used plants to treat infections. Russians used heated soil to heal infected wounds. Sumerian doctors provided beer soup mixed with turtle shells and snake skins for their patients. All the crazy ideas never compared to the discovery of antibiotics or antibacterial. Antibiotics are medicine that destroys microorganisms. They are many different types of antibiotics, some treat infections caused by bacteria (broad-spectrum…
