For about 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II, they treated one of the biggest killers during wartime, infected wounds. It was the beginning of the antibiotic era. But just when antibiotics wer...
Major Factor Of Bacterial Resistance To Antibiotics
2,179 wordsResistance Is Futile: The Dilemma of Antibiotic-Resistance Has man pinned the arm behind the back of Mother Nature Have humans finally won this terrible pathogenic onslaught Apparently not the Era of Epidemics has risen once again, and it looks as if humans are being bumped off the top of the food chain.

1,629 wordsHorror movies graphically reveal the ravages of killer plagues and flesh-eating bacteria, but behind this Hollywood hype is a story of real immanent danger. Antibiotic resistant strains of staph and strep are putting the lives and health of people at risk. When first discovered, about 75 years ago, antibiotics were touted as a miracle cure, which they literally were. Infections that were fatal before the turn of the century were turned into mere inconveniences over the last 75 or so years. But w...
Bacteria For Drug Resistance
1,790 wordsSince antibiotics, such as penicillin, became widely available in the 1940's, they have been called miracle drugs. They have been able to eliminate bacteria without significantly harming the other cells of the host. Now with each passing year, bacteria that are immune to antibiotics have become more and more common. This turn of events presents us with an alarming problem. Strains of bacteria that are resistant to all prescribed antibiotics are beginning to appear. As a result, diseases such as ...

Bacteria are everywhere: in water and soil and in the bodies of humans and other animals. The majority of bacteria dont have the ability to cause disease, but that doesnt mean that they are totally harmless. The problem arises when disease causing bacteria interact, and are frequently in contact with the commensal, or harmless bacteria. They serve as reservoirs for ...
Late Antibiotic Resistance
2,489 wordsANTIMICROBIAL RESISTANCE AND JUDICIOUS USE OF ANTIBIOTICS Antibiotics Antibiotics are chemical substances, many of them derived from microorganisms that suppress the growth of other organisms and sometimes kill them. In clinical practice, the antibiotics are used to treat bacteriologically proven infections and also in the prophylaxis of certain diseases. They are sometimes used in the blind or empiric therapy of presumed infection. A different principle governs the selection of antibiotics for ...
Bacterial Resistance To Many Antibiotics
4,163 wordsDuring 1997, an event doctors had been fearing finally occurred. In three geographically separate patients, an often deadly bacterium, Staphylococcus aureus, responded poorly to a once reliable antidote– the antibiotic vancomycin. Fortunately, in those patients, the bacteria remained susceptible to other drugs and was eradicated. But the appearance of S. aureus not readily cleared by vancomycin foreshadows trouble. Worldwide, many strains of S. aureus are already resistant to all antibioti...
Spread Of Antibiotic Resistance
221 wordsAntibiotic Antibiotic Resistance Antibiotic Resistance Antibiotic resistance occurs when bacteria that cause infection are not killed by the antibiotics taken to stop the infection. The bacteria survive and continue to multiply causing more harm. Widespread use of antibiotics promotes the spread of antibiotic resistance. The Centers for Disease Control and Prevention (CDC) estimates that about 100 million courses of antibiotics are provided by office-based doctors each year. Approximately half o...
407 wordsAntibiotic Resistance Darwin's theory Antibiotic Resistance Essay, Research Paper Darwin's theory of evolution can be explained like this; the environment acts as a selective agent, weeding out organisms less able to survive. Darwin described natural selection as a process in which organisms become better adapted to their environment. The organisms that evolved with beneficial variations are more likely to survive and reproduce, they pass on the favorable genetic material. Over time, the genetic...
