Where has antibiotic resistant bacteria came from?
Some bacteria in a species have traits that are different from others in that group. When using antibiotics, you are selecting for the ones that are resistant against that antibiotic. This has been called the survival of the fittest. Any time the environment changes, the animals in that environment will adapt to the change or die. This one reason that antibiotics should be used carefully and only for a good reason.
What antibiotic is good for strep throat?
Strep is resistant to antibiotics.
What is urine culture and sensitivity?
Urine culture is when a doctor orders a urine specimen to be evaluated in a lab to determine exactly what kind of bacteria are living in it and causing problems. "Culture" means to grow, and they literally grow the bacteria so that they can test different antibiotics on it. Some antibiotics may kill the bacteria, and some antibiotics have no effect on the bacteria. This is the "sensitivity" part. If a bacteria is sensitive to an antibiotic, it would be a good choice for treatment of the infection. If it is not sensitive, the it is resistant to the antibiotic and it won't produce a cure.
Can antibiotics cause resistance in bacteria?
A simple way to explain it is:When you have an infection and take antibiotics for it, the weaker bacteria are killed first, with the stronger ones surviving, or taking longer to destroy. So when you don't take the full round of antibiotics, the stronger bacteria are the ones left in your body, and they are the ones that will continue to multiply, resulting in a bacteria resistant to the antibiotic. This is why you should always take the full prescribed course of antibiotics.Also, when antibiotics are prescribed, the body's natural defense system (the good bacteria) are destroyed along with the bad bacteria. This is why you should always eat yogurt with active cultures or drink buttermilk while on antibiotics - the active cultures put the "good" bacteria back in the body.
What describes an antibiotic that is good for a human to take medicine?
The antibiotic kills or prevents the growth of harmful bacteria without causing side effects in the patient.
Why are some bacteria resistant to antibiotic drugs?
Bacteria can become resistant by many means. Antibiotics can affect several different parts of a bacterium such as cell wall synthesis (the penicillins affect this) or protein synthesis and several others. If for example an antibiotic affects cell wall synthesis by inhibiting an enzyme then if the bacteria mutates to overproduce that enzyme then it becomes resistant to that antibiotic at therapeutic concentrations. Or the bacteria could mutate so it does not need that exact enzyme any more and the antibiotic becomes useless. Some of the dangerous pathogens like methicillin resistant Staphylococcus aureus (MRSA) have acquired resistance to several antibiotics by selective mutation (otherwise known as evolution). Some bacteria are not so good at mutating or are less dangerous as pathogens so they cannot acquire resistance at all or as quickly.Other bacteria can produce spores which are very tough capsules which contain all the genes of a bacterial species but are not viable cells, the spores are highly resistant to antibiotics because they are very thick and do not carry out normal cellular functions so they are not affected by antibiotics. Anthrax and Clostridium dificille can form spores.Some bacteria like Listeria and in some cases Staphylococcus aureus can get inside the human cell like a virus and become resistant to the immune system and also to drugs because it is harder for drugs to get inside a human cell.
Can you cure a uti with penicilln 500MG?
Most likely no. Penicillin is essentially the oldest antibiotic on the market. Invented for mass usage around the 1942. Which translates to a very high risk that most bacteria will already have developed antibiotic resistance to the antibiotic penicillin. Thus, taking the antibiotic will probably do no good and can actually prolong the pain and the infection. I recommend you either talk to your doctor or find an antibiotic that is more effective and stronger. Yet, even then you still run the risk of have a UTI that is antibiotic resistant to the stronger medicine. For instance, I developed a UTI and the doctor tested my urine and said I had a UTI. Then she prescribed my antibiotics and I was still in pain three days later. My mom, who is a microbiologist, figured the bacteria strain I had was resistant to this drug. So she decided to test me again to see what antibiotics the bacteria was resistant to and what antibiotics the strain of bacteria was susceptible to. After a long painful week with alot of the azi analgesic pills that dye your urine red or orange, I finally received the drugs I needed and the pain began to subside after three day on the strong antibiotics. Anyways
What the abuse of antibiotic can do?
The abuse of antibiotics can have two effects. In the long term it can allow pathogens to become resistant over time. In the short term it can harm your body by removing good bacteria from your body which can have severe adverse effects on your health if done for too long.
Why should be antibiotics only taken by an advance of a qualified doctor?
This is a very good question. Most of the infections are viral infections and they do not need any antibiotic. Secondly most of the bacterial infections are mild and they also do not need antibiotic. Thirdly the dose, duration and selection of antibiotic needs a wise judgement. Which you can not decide. Forth reason is injudiciuos use of antibiotic can lead to emergence of antibiotics resistant bacteria. As you have in case of ndm 1 or superbug in your hand. This generation is responsible to the welfare of the coming generations. So in short the antibiotics should not be taken without the prescription of the qualified doctor.
How do you fight harmful microbes if antibiotics run out?
if you run out of antibiotics, and you still have harmful microbes in your body... GO BACK TO THE DOCTOR, the main reason antibiotic resistant bacteria develop is because patients don't stick to a good antibiotic dosage and frequency regiment, it is like giving your bronchitis a vaccination to the cure your doctor has administered to you, hope that answers your question
What are three properties an antibiotic should have?
It has few or no side effects in humans. it kills different types of harmful bacteria. It doesn't kill good bacteria.
How would you know an antibiotic is good for a human to take as a medicine?
The antibiotic is safe if it kills or prevents the growth of harmful bacteria without causing side effects in the patient.
