What are the relative causes for antibiotic resistance?

Question

(a) overprescription of antibiotics (by doctors)?
(b) noncompliant use (by patients)?
(c) inadequate period of treatment (by reduced precriptions)?

Please discuss and weigh each.

Answer 1

(a) overprescription can cause unnecessary usage of antibiotics that the body will build up a tolerance to and render them useless

(b) once patients stop taking antibiotics when they start feeling better instead of completing the cycle, the infection or virus still remains in the system and can mutate into a different strain

(c) is a result of b.

Answer 2

It is a fact that, for a given antibiotic, there are different rates of resistance by country. Based on my experience as a clinical trials statistician, I propose the following: Number one, with over 75% of the reasons for resistance: over prescription by doctors. Not all their fault. Patients go from one doctor to the next, so their antibiotic history is not totally compiled. Also, due to allergic reactions there just aren't that many choices available. I would say number two is noncompliance, it is true patients fail to take the meds for the full time as prescribed, since these are not pain killers, patients tend to mismanage this area, 20%. Reduced prescriptions? Not from what I have seen, but I'll give it a 5% as there may be cases where a subject needs more than what is prescribed, or is given an inadequate does due to their weight.

All of the above ..Though some people clearly need to be treated with antibiotics.. many people are concerned about the inappropriate use of this medication. Many consumers/clients/patients have an expectation that when they're ill.. antibiotics are the answer. They put pressure on the doctors to prescribe them... Most of the time the illness is viral.. and antibiotics are not the answer. This large burden of antibiotics is certainly selecting resistant bacteria.

The increased prevalence of antibiotic resistance is an outcome of evolution.. A population of organisms... bacteria included, develope the ability to withstand an antibiotic's attack on a microbe.... When a person takes an antibiotic the drug kills the defenseless bacteria.. leaving behind or selecting/choosing in those that can resist it... These so called renegade bacteria then multiply.. increasing their numbers a millions in a day becoming the predominant microorganism...

inadequate period of treatment.........Though bacterial antibiotic resistance is a natural occcurance.. societal factors also contribute to the problem... These factors include increased infection transmission.... coupled with inappropriate antibiotic use...Patients using antibiotics and not completing a course..eg. stopping when they feel better..and then ofcourse many practitioners prescribe shorter periods of treatments aswell...3 day courses or a one day course.... Kind regards AMF

It mostly depends on the person and their metabolism. I for example can take a certain prescription for a about three days before I have already built up a resistance, while my sister has been taking a prescription for about 4 months and it still effects her the same as the first day.

Over prescription might cause a resistance, but mostly would just cause more side effects, or in extreme cases, an overdose, resulting in minor to major damage, and maybe even death.

Non compliant use would be about the same, but only if they increase the amount of prescription taken, and even then, it could still take a while before resistance is built up.

By reducing prescriptions you can actually reduce the amount of time to build a resistance, if a resistance is possible.

Most of the the possibility of building a resistance results from the person Immune system AND metabolism.

I hope this answers your question.

Answer 5

Probably the reason(s) for antibiotic resistance is the overexposure of this antibiotic, there are some cases I heard about that having too much antibiotics could cause them to disbursed and mistaken other cells as a germ or a virus and the body has no choice but be defensive. Another reason could probably be tolerance, if you believe the theory of evolution, this predicament occurs very rarely to most people. But then again i'm not very sure nor accurate in this information, my recommendation is talk to your doctor about antibiotic resistance.

Answer 6

All of the above are causes of antibiotic resistance, There is one more reason why antibiotics don't work to add to your list: consumers are using antibiotics everyday: antibacterial wipes and soaps are used regularly at homes and offices where there is no reason to use them. By using too much antibacterial products, the normal flora of the skin dies. Normal flora of the skin is the first line of defense for the body. Think of normal flora as a bunch of bacteria that kill other bacteria or keep their population under control, a relationship like cats and mice.
The other thing is that we all consume a large amount of antibiotics through our food. Unless you are growing your own vegetables and chickens and cattle, every thing you by from store has antibiotics in it.

Answer 7

2 reasons, symptom relief does not equal cure and it encourages bacteria to become resistant

Answer 8

Too much given to animals which we then eat.

Answer 9

to me its not really important but i know that
OLIVE LEAF EXTRACT IS THE BEST, THE SAFEST & THE MOST NATURAL PLUS IT PROTECTS FROM INFECTIONS, PARASITES & VIRUSES its the lifesaver of the 21st century!!
