Explain how the excessive or inapporopriate use of antibiotics poses health hazard for a human population.?

Answer 1

Antibiotics wipe out the beneficial bacterias in your digestive tract that are a huge part of your immune system.

Even though you haven’t had a written prescription for an antibiotic, chances are very high you have still taken significant amounts of antibiotics during the past few months. You see, animals (including cows, pigs and chickens) are fed antibiotics in order to keep them well and to promote growth. In fact, in North America, half of the antibiotics produced, over 20 million pounds each year, are fed to animals. Dairy products as well contain high levels of antibiotics.

Most of us are unfamiliar with the benefits of probiotics and the danger we put ourselves in when we fail to take advantage of those benefits. Probiotics are living organisms, also known as good bacteria or flora, that give great benefit when they colonize and flourish in the healthy intestine. These good bacteria are vital to your health and to the proper functioning of your intestinal tract. In fact, the healthy intestine contains approximately three pounds of good bacteria.

These benefit of probiotic or good bacteria strains is they function as a backup to your body’s immune system. Probiotics promote health by secreting antibiotic like substances, such as lactic acid, acetic acid, hydrogen peroxide and others. Though these probiotic substances are produced in tiny amounts, they have a wide range of benefits in activity against salmonella, pseudomonas, E. coli and other harmful food borne bacteria. When the intestine is flourishing with good bacteria, there is no room for harmful, disease causing strains of bacteria to implant in you and grow.

Answer 2

Antibiotics are made for particular bacteria. There are different kinds of antibiotic. They are classified also according to generation (strength ) and whta particular group of bacteria they react to. So if a patient is infected with a bacteria that is common (and maybe classified as susceptible type ) a first generation antibiotic can be prescribed BUT IT MUST BE TAKEN BY THE PATIENT FOR AT LEAST ONE WEEK (7 DAYS). This is sometimes the reason why resistant strains evolve. The patient will just take the anitbiotic for like 2days and after they feel okay, they won't take it as advised. They did not know that the bacteria just became in active (not killed ) and they will soon "learn" to defend themselves against the effects of antibiotic then later become immune. The doctor then will think that the patient did not respond well to the first generation antibiotic and jumps to the 2nd then the 3rd until the patient becomes so immune with these antibiotic, the bacteria becomes so strong.When this happens, we are making strains of bacteria non-curable. They will just continue to evolve. That is why docotrs are advised to prescribe properly and educate their patients on tkaing anitbiotics according to what is advised. hope this helps. God bless

Answer 3

The inappropriate and/or excessive use of antibiotics causes virus' to mutate and become immune to known antibiotics. This is why the drug companies are constantly looking for new antibiotics. Having the disease become immune to the cure is certainly a BIG health hazard for the human population.

Answer 4

Bacteria is gaining immunity to our antibiotics. When a person takes an antibiotic, it kills off most of the "problem". However, there's a little thing called evolution! Through the magic of genetic mutation, some of the "problem" develops a resistance to the medicine.

Answer 5

Even when used properly, antibiotics can sometimes wipe out the beneficial bacteria in the body, leaving your child vulnerable to deadly attack from the resistant and harmful ones. And because of overuse, many bacteria have become resistant to even our most powerful antibiotics – which poses a HUGE danger to your child if he becomes infected with one of these resistant strains.

Answer 6

The system gets used to antibiotics and they become less and less effective. Then when a serious infection strikes, the antibiotic doesn't work.
