Antibiotic resistance in bacteria essay

Read now History People generally attribute the discovery of penicillins to Alexander Fleming. The story goes that he returned to his laboratory one day in September to find a Petri dish containing Staphylococcus bacteria with its lid no longer in place. The dish had become contaminated with a blue-green mold called Penicillium notatum. Fleming noted that there was a clear ring surrounding the mold where the bacteria had been unable to grow.

S patients due to several types of bacteria most data condensed from text in Frieden Health care costs Antibiotic resistance is a financial burden on the healthcare system. Physicians are obligated to treat individual patients with the most effective drugs for an infection.

Health care institutions believe that hospital expenses is a form of reimbursing physicians for their service to the society Roberts et al. Patients, on the other hand, demand a better healthcare service, better quality of life for them and for those around them Roberts et al.

Antibiotics for bacterial infections are costly, and sometimes hospitalization is required until the infection is cleared, further raising costs Roberts et al.

Currently, several elements have played a vital role in the cost of controlling infection. Not only are novel antibiotics needed, but surveillance within each hospital must be augmented Slama Hospital administration plays a vital role on controlling resistant pathogens, as well as enforcing rules to limit resistant strains from spreading.

Hospitals or medical centers can only initiate surveillance programs or policy changes to improve infection control if there is financial support. Without financial support, resistant pathogens will continue to develop and spread, and the quality of health care worldwide will be drastically affected Slama Are we in the post-antibiotic Era?

Combination work-outs (cardio/weights) and yoga, ballet, walking, not to mention cycling as my main source of transportation, keeps me in shape and in health.


Salvador Edward Luria (August 13, – February 6, ) was an Italian microbiologist, later a naturalized U.S. won the Nobel Prize in Physiology or Medicine in , with Max Delbrück and Alfred Hershey, for their discoveries on the replication mechanism and the genetic structure of viruses.

Salvador Luria also showed that bacterial resistance to viruses is genetically inherited. Fermented foods, such as sauerkraut and kombucha, have become popular for health reasons. I have made my own sauerkraut in the past and have recently made the tasty, fermented Korean side dish, kimchi.

I did it not only for the taste but also for the hope that the bacteria responsible for the. EVOLUTION AND CLASSIFICATION. 1. BACTERIA are microscopic unicellular Prokaryotes. 2. Bacteria are the MOST NUMEROUS ORGANISMS ON EARTH.

3. Bacteria have evolved into many different forms, and they are now part of nearly every environment on Earth. Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them.

That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

In most cases. Drug resistance is the reduction in effectiveness of a medication such as an antimicrobial or an antineoplastic in treating a disease or condition.

The term is used in the context of resistance that pathogens or cancers have "acquired", that is, resistance has evolved. Antimicrobial resistance and antineoplastic resistance challenge clinical care and drive research.
