The theory is that any time you use an antibacterial agent, you can only kill 99.99% of the bacteria, while the remaining 0.01% may be bacteria more resistant than the original. When those few remaining bacteria multiply, they may be more difficult to destroy.
Give fewer antibiotics to humans and animals. Ensure that when antibiotics are given, they are used in sufficiently high dosages and for long enough to kill as many bacteria as possible.
I'm not sure if you could specify? I just learned about antibiotics in biology this year (I'm a sophomore) and I can tell you something though: do not give antibiotics to your animals to promote growth. It is sorta like taking antibiotics when you're sick. They help you, but can be deadly. It goes the same for animals too. Antibiotics can be deadly because there are such things that may exist in our bodies called MUTANT BACTERIA STRAINS. These strains will not respond to antibiotics when the other bacteria die off. MUTANT BACTERIA STRAINS will stay alive. and worse, multiply. And then you have a whole swarm of mutant bacteria strains in your body that can't be taken away with antibiotics. So when you give certain livestock antibiotics to promote growth, you're risking possession of mutant bacteria in your body when you eat their meat. The animal may have mutant bacteria strains already and you don't know it. So when you eat the animal, you're risking getting these bacteria strains. Sorry if that didn't help, but you may have learned something vital instead.
Most normal antibiotics won't work on MRSA. get your doctor to give you a round of Vancomycin. That'll do it.
Because the most resistant bacteria will be the last to die. If you stop the course before every bacterium is dead the resistant survivors will multiply and be much harder to kill next time.Plus eventually new totally resistant strains would develop somewhere in the world and that might mean the end of the human race.So EVERYONE, EVERYWHERE, EVERY TIME must finish the prescribed course.---Dramatic, but true.Every time someone doesn't finish their course, they risk creating increasingly-resistant strains of the same bacteria.At best, you don't clear the infection and have to take a second course of antibiotics.At worse, you find yourself with an infection that you can't clear.For the sake of a couple of days extra effort, just finish the prescribed course.
Antibiotics kill bacteria by recognising the antibodies secreted by the bacteria, then attach themselves to the bacteria and give out a signal calling for white blood cells (phagocytes) to eat up the bacteria. Viruses do not secrete the antibodies recognised by antibiotics as they do not resemble proper cells, therefore antibiotics cannot recognise viruses and thus they cannot be digested by phagocytes.
antibiotics should not be over used because antibiotics taken unnecessarily may kill the beneficial bacteria in the body.
Frequent use of antibiotics can cause bacterial resistance. When bacteria are exposed to an antibiotic more than once, it can start to become immune to it. Antibiotics can also cause birth defects and other health problems. Soap and hot water works just as effectively.
I think they made medicine for stomachs from the helpful digesting helper bacteria in pills.
Using antibiotics when ineffective or unnecessary enables the mutation and spread of antibiotic-resistant bacterial strains, since the bacteria will get small and/or a short duration of doses of the medicine, too short to kill the bacteria, but able to make them get used to the "poison" and no longer killed by it. That is why you are told by medical professionals that you should always take all antibiotics prescribed even when you start feeling better, because it takes the full amount of medicine to be sure the bacteria have been killed. You are also told not to skip doses for the same reason. Do not pressure your physician to prescribe antibiotics for a cold. Antibiotics are not a direct treatment of viruses that cause colds and flu, they have no affect on any viruses. They are only prescribed with viral illness if there has been a secondary bacterial pneumonia or other bacterial infection develop. If you take antibiotics when unnecessary, you also contribute to the production of more antibiotic-resistant bacteria. It is coincidental when people say that they know that the antibiotics they took for a cold or flu virus made them feel better. It is a matter of time, not medicine. Often people do not seek physician exam until they have had a cold for 5-7 days...and then within 3 days of starting the antibiotics, they begin to feel better and attribute it to the antibiotics. But it is not due to the medicine, it is due to the time it took your body to rid the virus, which is in 7 to 10 days from the start of symptoms. Just wait for at least 10 days to give your body a chance to heal your virus before pressuring for unneeded antibiotics. Antibiotics are not innocuous. They have toxicities and side effects. This means that antibiotics not only do no good in a viral infection, they can actually harm the patient. This is at odds with a fundamental precept of medicine: "First, do no harm."
Antibiotic resistance results from misusing antibiotics. Antibiotics should only be used to treat bacterial infections. Many industrial farmers will give healthy animals a daily dose of low level antibiotics to stimulate growth. These daily doses help to create antibiotic resistant super bugs.
Antibiotics. A major contributor to ulcers is the helicobacter pylori bacteria.
You should never give antibiotics to any patient - cat, dog, human - without a prescription. The reason is that antibiotics only work for certain types of bacteria - if you use them for diseases that cannot be treated with that type of antibiotics, the medication will do more harm than good. It will not cure the disease, but the patient can experience unwanted side effects. In addition, misuse of antibiotics contributes to creating resistant bacteria that can cause very problematic diseases. Your vet will tell you what type of antibiotics, if any, your cat needs, and if leftover medication from your dog will do.
