Title: Antibiotic resistance
Author: Medicine Net

The argument is persuasive and this article gives a little bit of history of the antibiotic resistance bacteria.  The microbes are living organisms that reproduce, thrive, and spread quickly and efficiently. Microbes include bacteria (e.g., Staphylococcus aureus, which causes some staph infection), viruses (e.g., influenza, which causes the flu), fungi (e.g., Candida albicans, which causes some yeast infections), and parasites (e.g., Plasmodium falciparum, which causes malaria).
Antimicrobial is a general term given to medicines that kill or slow the growth of microbes.But when the microbes get resisted to the antibiotic they reproduce and is impossible to kill it. There are data in this article which has pictures that shows the bacteria are grown and what people do to increases the antibiotic resistance bacteria. Author of this article shows the history of how antibiotics were made. It sates that "In 1928 while working with Staphylococcus bacteria, Scottish scientist Alexander Fleming noticed that a type of mold growing by accident on a laboratory plate was protected from, and even repelled, the bacteria. The active substance, which Fleming called penicillin, was literally an antibiotic-it killed living organisms. It also states the problem with the antibiotics,
After more than 70 years of widespread use, evolution of disease-causing microbes also has resulted in many antimicrobials losing their effectiveness. As microbes evolve, they adapt to their environments. If something stops them from growing and spreading-such as an antimicrobial-they evolve new mechanisms to resist the antimicrobials by changing their genetic structure. Changing the genetic structure ensures that the offspring of the resistant microbes also are resistant. Antimicrobial resistance makes it harder to eliminate infections from the body. As a result of a microbe's ability to survive in the presence of antimicrobials, some infectious diseases are now more difficult to treat than they were just a few decades ago. In fact, antimicrobials have helped people so effectively that humans are hurting the protective value of medicines through overuse and misuse. More prudent use of antimicrobials will help to slow the development of resistance.
This is not the primary text but the information on this text is relevant and useful. I didn't know There are differences between this article and the other article because this article explain the history while the other articles explains the consequences and careless mistakes of people. The critical question could be answered by this article but also many question can be brought up because the history can't always be true. It is always interpreted.
