Explain why the over-prescription of antibiotics can lead to antibiotic-resistant forms of bacteria. (MRSA) (D2)
As we know antibiotics helped us to destroy many of dangerous bacteria that made us ill because we have been used it in the way to create resistance. But after a long time, antibiotics have lost their effectiveness against some bacteria. An example is MRSA (methicillin-resistant staphylococcus aureus) which is a form of bacterial infection. Staphylococcus bacteria live on our skin and in our noses without causing any problem, but when this become resistant to antibiotics it can causes grave infections principally for people that are ill or weak. MRSA bacterium is resistant to many antibiotics such as methicillin, amoxicillin, penicillin and oxacillin. When these antibiotics do not kill the bacteria causing an infection, it becomes harder to get rid of the infection.
Antibiotic resistance is a main problem determined by over prescription of antibiotics and them being prescribed incorrectly. Wrong use of antibiotics can lead to increasing levels of illness and death, increasing period of patients to stay in hospital, increasing the number of patients to be injected with resistant bacteria and increasing difficulty in treating the infection that resistance to bacteria.
In recent years, the overuse of antibiotics had a major impact in antibiotic resistance because the antibiotics were used to treat minor illnesses which could be treated anyway, as examples for coughs, colds and pains; also used for infections but not finishing the course prescribed.
Bacteria become resistant to antibiotics when it changes in a way that eliminate the efficiency of drugs. Then the bacteria lives and continue to multiply producing more damage. This can happen in some ways: when bacteria develop the capacity to cancel out the antibiotic before doing damaging, some bacteria pump out the antibiotic and some of them can change the attack of antibiotic, so it cannot have an impact to the bacteria function.
Antibiotics are able to destroy many strains of bacteria, but if you are treated over-prescription, your immunity will decease and let the bacteria to multiplying it. Antibiotics used too often can kill the weak bacteria in the body but leave some of the resistant bacteria to grow and spread. The resistant bacteria can keep in the body causing infection to the same person or can be spread to other persons to make them sick with the bacteria that is difficult to be treated.
