What is an anti-microorganism?
Antimicrobial resistance is similar to antibiotic resistance. Microbes evolve to survive exposure to both antimicrobials and antibiotics when such products are used excessively or inappropriately.
Why do researchers need to constantly develop new types of antibiotics?
Because people (including doctors) keep using antibiotics for inappropriate purposes, including treatment of the common cold, which is a virus. Viruses are not affected by antibiotics. Constant exposure to antibiotics in the environment has resulted in mutations of bacteria so that they are antibiotic resistant. Thus, it is necessary to continue to develop new antibiotics to deal with these new super-bacteria. It should be said that the drug companies themselves are largely responsible for this, as they constantly lobby to allow antibiotics to be used unnecessarily, such as in treatment of poultry and other animals that are to be slaughtered for meat. This saves money, but it also releases huge amounts of drugs into the environment. (See above for results) The pharmaceutical giants thus get richer in two ways: selling the old drugs and developing and marketing new ones.
The rate at which a rock in a streambed dissolves would not be increased by?
Reduce the rocks exposure
What is the problem with antibiotic resistance?
There has been, and still is a lot of abuse, in the direction of excess prescription, or necessary prescription of antibiotics. This gives an open door to bacteria to develop an immunity to many antibiotics, just to the point where certain infections, such as staphylococcus, streptococcus and other potentially mortal infections , becoming completely untreatable by the usual antibiotics, and in certain cases, by any antibiotic. Certain types of staphylococcus in particular are potentially mortal, especially those of a hospital origin, being immune to all known antibiotics. Although many doctors now are aware of the dangers of excessive usage of antibiotics, it is, unfortunately, a bit late in certain cases.
Certain bacteria produce a chemical that makes them resistant to penicillin since these bacteria reproduce asexually they usually produce offspring that?
survive exposure to penicillin
Why is it important to know which species of bacteria are susceptible to which antibiotics?
If bacteria are susceptible to antibiotics, exposure to antibiotics will lead to the death or weakening of the bacteria.
Why should't doctores over prescribe antibiotics?
Because the organisms that the antibiotics kill (to make you better) evolve resistance to the antibiotics when they are exposed to them. This means that the more the exposure (prescribing) the faster resistance develops. Antibiotics should therefore ONLY be used when really needed and taken EXACTLY as they are meant to. Stopping a dose of antibiotics before a full course of treatment is worse than over prescribing.
Why are antibiotics less effective now than they once were?
Unfortunately, antibiotics are less effective today than they once were. Over the years, many bacteria have become resistant to antibiotic. Antibiotic resistance results when some bacteria are able to survive in the presence of an antibiotic. CREDITS FROM: NORTH CAROLINE 8TH GRADE PRENTICE HALL SCIENCE EXPLORER
What treatment is the most appropriate for aerosole exposure?

What are the benefits of Spotify Promotion?
• Increased Exposure • Increased Exposure • Improved Discoverability • Boost in Fanbase • Increased Credibility Overall, playlist promotion can be a valuable tool for musicians looking to increase their exposure and reach new listeners on Spotify.
What is the effect of longer exposure to ultraviolet light?
Prolonged exposure to ultraviolet light can have a number of effects on bacteria. For example, the exposure can lead to mutations in the bacteria's DNA or complete eradication of the bacteria, giving UV light antibacterial properties.
What does overdose of antibiotics do?
antibiotics are save thing and very benefit for our body because it would fight against bacterial infections as we know there are very benefical but it also effect our body if we take overdose.... we should avoide this thing and consulation with docter about your disease if a person taking overdose it would effect on their lungs, he face difficulties in breathing, high blood pressure
How has the WNBA changed?
Yes. Rule changes, talent changes, attendance changes, exposure changes.
How do you catch conjunctivitis?
From exposure to a person who already has trachoma or from exposure to clamydia trachomatis bacteria.
What is one advantage of restricting the use of antibiotics?
The germ causing the infection can become resistant ("immune") to the antibiotic, then it will basically make it useless in the fight against that germ.
Why do scientists have to find a new antibiotic to kill bacteria?
After releasing enough of one type of antibiotic onto some bacteria, given enough time the bacteria will adapt, and even change to be unaffected by the given antibiotic. The only way to inhibit the bacteria then is find a new, better antibiotic, after which, given enough time and exposure, the bacteria will get used to this antibiotic, so there is again a need for a new one.
