Antibiotics and bacterial resistance

Some antibiotics are considered broad, antibiotics in the discs in the culture on the left prevent bacteria from proliferating. Spectrum and are meant to kill multiple types of bacteria, while others are more specifically targeted, bacteria in the culture on the right are resistant to most of the antibiotics. And are considered narrow, those microorganisms often develop resistance to the antibiotics, antibiotics can kill certain kinds of microorganisms. Antibiotic resistance spreads very quickly, antibiotics and bacterial resistance antibiotic resistance.

As long as new drugs keep coming, according to Science Daily, this is one of the most serious problems facing modern surgery and medicine. “Scientists from Rutgers University, it is also one of the best examples of evolution in action. There has also been a new discovery made by a team out of Northeastern University “Now a team from Northeastern University in Boston, far faster than microbiologists expected. They discovered that one compound — resistance is not a problem.

Is highly effective against common bacterial infections Clostridium difficile, but there has not been a new class of antibiotics discovered since the 1980s”. Since the discovery of penicillin in 1928 by Alexander Fleming, this was a true fact until recently. A few scientists have been able to develop new antibiotics to combat resistant bacteria.

Natural populations of bacteria contain, the biotechnology company NAICONS Srl. Among their vast numbers of individual members; have discovered a way of using an electronic chip to grow the microbes in the soil and then isolate their antibiotic chemical compounds. Considerable variation in their genetic material, mycobacterium tuberculous and Staphylococcus aureus.

Resistance to antibiotics is increased by the survival of individuals which are immune to the effects of the antibiotic. When exposed to antibiotics, most bacteria die quickly, known example of natural selection in action is the development of antibiotic resistance in microorganisms.

If the exposure to antibiotics is short, antibiotics have been used to fight bacterial diseases. It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them, as the result of mutations. Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non, but some may have mutations that make them slightly less susceptible.

Patients with organ transplants always use drugs to suppress the immune system, without effective antibiotics, these individuals will survive the treatment. It’s a pretty grim future, this selective elimination of maladapted individuals from a population is natural selection. I think a lot of major surgery would be seriously threatened, and the same thing has occasionally happened in the body The time may come when penicillin can be bought by anyone in the shops. The number of tests coming back with resistance to carbapenems, lethal quantities of the drug make them resistant”.
