branch of science is the invention of antibiotics. An antibiotic is a substance produced by one organism that can destroy another. The term literally means “against life.” One of the earliest discovered and widely used antibiotics is Penicillin. Penicillin is collected from the Penicillium mold. Alexander Fleming is known for discovering this antibiotic. In 1901‚ he went to St. Mary Hospital to study medicine. In 1914‚ during World War I‚ Alexander Fleming joined the British Royal Army Medical

Scottish biologist and pharmacologist. He was born at Lochfield near Darvel in Ayrshire‚ Scotland on August 6th‚ 1881. In 1999‚ the Times magazine named Fleming one of the 100 Most Important People of the 20th Century for his discovery of penicillin. While penicillin is widely cited as one of the most important discoveries of the 20th century‚ uncertainty over whether or not Alexander Fleming actually discovered it caused many to question his 1945 Nobel Prize for Medicine. Critics questioned the novelty

This report by Wright‚ Seiple‚ and Meyers discusses mainly the history of antibiotics as well as its link to future discoveries. Each section in the report examines different points throughout the essay: 1) The authors suggest chemical synthesis as the key to the development of the first antibiotic. All antibiotics discovered by humans have been categorised into one of the following: natural products (manufactured directly by bacteria)‚ semisynthetic antibacterials (manufactured by chemical synthesis

Ampicillin‚ a beta-lactam semi-synthetic aminopenicillin‚ acts as a bactericidal agent against microorganisms by inhibiting cell wall synthesis during active multiplication Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin binding proteins (PBPs); which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls‚ thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes

Amoxicillin is an antibiotic in the penicillin class that destroys bacteria. The mechanism of action of amoxicillin involves inhibition of bacterial cell wall synthesis. Therefore‚ it is valuable in destroying actively growing and cell wall synthesizing bacteria. Lysis of bacteria causes a lack of bacterial cell wall leading to death. Amoxicillin is used to treat several forms of infections of the nose‚ ear‚ skin‚ urinary tract‚ or throat and other infections caused by bacteria‚ such as bronchitis

There were eight antibiotics used for this experiment; chloramphenicol (C)‚ erythromycin (E)‚ fusidic acid (FC)‚ oxacillin (OX)‚ novobiocin (NO)‚ penicillin G (PG)‚ streptomycin (S)‚ and tetracycline (T). The mode of action of Chloramphenicol is the inhibition of protein synthesis. Chloramphenicol irreversibly binds to a receptor sit on the 50S subunit of the ribosome on the bacteria that inhibits the enzyme peptidyl transferase. This inhibition results to the prevention of the transfer of amino

The studies from “You Decide: What Can We Do About Antibiotic-Resistance Bacteria”‚ show how antibiotics affect bacteria over time. From 1995 to 1998 the resistance of penicillin by the bacteria known as Streptococcus Pneumoniae increased consistently. If patients continue to become resistant to the antibiotics being prescribed then the antibiotics could become extinct in the sense that they would no longer be valuable for

Methicillin-resistant Staphylococcus aureus (MRSA) Jessica Heinen Autry Technology Center Introduction The full name of MRSA is meticillin-resistant staphylococcus aureus. Staphylococcus aureus (also known as staph) is a common type of bacteria. It is often carried on the skin and inside the nostrils and throat‚ and can cause mild infections of the skin such as boils and impetigo. If staph bacteria get into a break in the skin‚ they can cause life-threatening infections‚ such as
