In her Ted Talk‚ Maryn McKenna illustrates the danger that humanity was in before the rise of antibiotics‚ and the future risks that will arise if further intervention on antibiotic resistance is not done. She describes that in the past‚ before penicillin was discovered by Alexander Fleming‚ infections were the primary cause of death and most people did not live past the age of forty.

believe that the discovery of the fist antibiotic‚ penicillin played a crucial role in the history of mankind.

key: injecting penicillin into infected mice. Fleming’s initial work was reported in 1929 in the British Journal of Experimental Pathology‚ but it would remain in relative obscurity for a decade. By 1932‚ Fleming had abandoned his work on penicillin. He would have no further role in the subsequent development of this or any other antibiotic‚ aside from happily providing other researchers with samples of his mold. It is said that he lacked both the chemical expertise to purify penicillin and the conviction

ANTI-INFECTIVES Anti-infective agents are drugs that are designed to act selectively on foreign organisms that have invaded and infected the body of a human host. Ideally‚ these drugs would be toxic to the infecting organisms only and would have no effect on the host (or human) cells. OVERVIEW • Antimicrobial therapy (often termed “antibiotic therapy”) is the use of medications to treat infections caused by bacteria‚ viruses‚ and fungi. • Antimicrobial must use selective toxicity to kill

Lab Report: Antibiotic Evaluation by the Kirby-Bauer Method Introduction Chemical antimicrobial agents are chemical compounds capable of either inhibiting the growth of microorganisms or killing them outright. Those which are taken internally to alleviate the symptoms of or promote healing from disease are called chemotherapeutic drugs‚ and among these is a class of compounds called antibiotics. In order for a chemotherapeutic drug to be classed as an antibiotic‚ it must be produced by
