How do bacteria strains like pneumonia become immune to antibiotics?
They become immune by mutating and blocking certain receptors on the bacteria's surface, which would normally be where the antibiotics would attach to.
Why are antibiotics not given unless a serious infection?
Bacteria can become immune to antibiotics and the antibiotics will not work in the future when you need them. They only work against bacteria and cold and flu are caused by viruses.
What will happen to bacteria if antibiotics are over used?
The bacteria will become immune to the antibiotics.
Why would antibiotic dosages be decreased?
To not use too much so that the bacteria can become immune to the antibiotics and become superbacteria.
Can you identify a possible risk of overuse of antibiotics?
bacteria and fungi will become immune to them, causing infections such as MRSA.
Why won't som antibiotics cure bacterial?
One possible reason could be that the bacteria has some how become resistant to the antibiotics used to fight it. If you take a certain antibiotic often, your body will start to become immune to its effects. Then when that antibiotic is needed to fight a bacteria, your body no longer registers the antibiotics as a way of killing the bacteria.
What are bacteria diseases immune to antibiotics?
because antibiotics such as penciline have immunity to defend the bacterial attacks
Do antibiotics cause bacteria to become resistant?
Yes, over use of antibiotics can cause bacteria to become resistant.
Why does mutant bacteria survive in hospital environments?
Hospitals are rich with antibiotics. These will kill most bacteria, but those that survive often become resistant. At a hospital bacteria can become resistant to a variety of antibiotics and can pass from one patient to another, many of whom already have weakened immune systems. It is a good example (for the bacteria anyway) of "what doesn't kill you only makes you stronger."
Why might a physician be likely to develop bacteria that are resistant to all antibiotics?
The bacteria may have grown in an environment where it is introduced to the antibiotics therefore making it immune to the drugs.
How antibiotics predispose animal for disease?
Antibiotics not only kill bad bacteria, they kill good bacteria, antibotics cannot know the difference, killing the good bacteria hurts the immune system.
Explain how the process of natural selection results in populations of bacteria that are not harmed by antibiotics?
The process of natural selection results in populations of bacteria that are not harmed by antibiotics because bacteria that are born with mutations that make them immune to antibiotics will be the ones to survive and reproduce.
